Forces And Motion
Posted on 21-Mar-2021
Contrasting student and scientific views Student everyday experiences It is very difficult to tell with the naked eye if an object is accelerating for example, a ball flying through the air and so students do not tend to think of motion in terms of whether it is accelerated or not. Accelerated motion is also a difficult concept for students because it occurs when an object changes either speed or direction or both. Students are familiar with objects accelerating from rest or braking, for example a car speeding up or to a lesser extent slowing down at the traffic lights. However, it is much more difficult to determine if an object already moving is changing its speed unless the change is dramatic.

Students seldom identify a car turning a corner at constant speed as accelerating because their common understanding requires the object to be changing speed for it to be accelerating. These rules appear to work when students ignore friction and air resistance; friction and air resistance are generally not seen by students as involving forces. These ideas are also discussed in the focus idea Friction is a Force.

Research: Mitchell A common view that persists at this level is that a moving object must have a force acting on them in the direction of their motion. Some students also strongly believe that this force is being used up if the object is slowing down. Net force is a valuable construct that has no separate existence of its own, unlike the real forces acting on the object, i. When there is a net force on an object, it causes the object to accelerate in the direction of the net force; this is not the same as the direction of the motion unless the object is going in a straight line. Critical teaching ideas An object accelerates when its speed changes or its direction of motion changes or both. The net force on an object is the combined effect the sum of all the pushing and pulling forces actually acting on the object. If the forces pushing or pulling on an object are not balanced a net force acts then the object will accelerate in the direction of the net force.

These are each covered in greater detail in the sequence of teaching ideas introduced at the lower levels: A net force on an object changes its motion — the greater the net force, the greater the acceleration. More massive objects require bigger net forces to accelerate the same amount as less massive objects. It can be represented diagrammatically by an arrow drawn through the centre of the book directed downwards towards the Earth. Students need exposure to situations that require verbal explanations about the forces involved before they are exposed to quantitative work involving formulae. A simple mathematical relationship exists between the mass of an object m , the net force on the object f and its acceleration a. They can then be asked to identify all the actual forces and the net force on objects in a wide range of motion contexts. Some examples include: a ball rolling along a table; a ball that was rolling on a table but is now stopped; a ball thrown up in the air that is moving upwards or downwards ; a skateboard rider moving down a gently sloping path at a constant speed.

E Place a puck on air table and ask students to predict how they would keep it moving at a steady speed by pushing on it with a ruler. Most students are surprised that it is impossible to achieve a steady speed with this action and are intrigued as any amount of push with the ruler makes the puck keep 'running away from them'.

We state that the surroundings exert a force on the object studied. Under the influence of a force, an object will accelerate. The force laws allow us to calculate the force acting on a body from the properties of the body and its environment. The laws of motion are subsequently used to calculate the acceleration of the object under influence of the force.

Newton's Understanding Of Forces And Motion

In this course we will be discussing the laws of motion obtained by Newton. This is called Newtonian mechanics. It should be realized that Newtonian mechanics does not always provide correct answers. If the speed of the objects involved is an appreciable fraction of the speed of light, we must replace Newtonian mechanics by Einstein's special theory of relativity. For problems on the scale of atomic structure we must replace Newtonian mechanics by quantum mechanics. Newtons First Law All around us we observe that all moving objects will come eventually to rest, unless we apply a force to them.

In all these cases, friction will ultimately stop any moving object, unless the friction force is canceled by the force supplied by our legs, our engine, etc. If we reduce friction, the moving object will take longer to slow down, and the force needed to overcome the friction force will be less. In the limit of no friction, our object will keep moving with a constant velocity, and no force need to be applied. This conclusion is summarized in Newton's first law: " Consider a body on which no net force acts. If the body is at rest, it will remain at rest. If the body is moving with constant velocity, it will continue to do so.

Reference frames in which Newton's first law applies are called inertial reference frames. One way to test whether a reference frame is an inertial reference frame, is to put a test body at rest and arrange things so that no net force acts in it. If the reference frame is an inertial frame, the body will remain at rest; if the body does not remain at rest, the reference frame is not an inertial frame. If you put a bowling ball at rest on a merry-go-round, no identifiable forces act on the ball, but it does not remain at rest. Rotating reference frames are not inertial reference frames. Strictly speaking, the earth is therefore also not an inertial frame, however, only if we consider large scale motion such as wind and ocean current do we need to take into account the non inertial character of the rotating earth.

Force If we exert the same force on several objects with different mass, we will observe different accelerations. For example, one can throw a baseball significantly further and faster than a ball of similar size made of lead. Experiments have shown that the force is a vector. This can be shown by demonstrating that the force has a magnitude and a direction. Suppose, we apply a force of 3 N to our standard object mass 1 kg. The situation is illustrated in Figure 5. The total force is 5 N and is equal to the magnitude of the sum vector of the two forces if we assume that the direction of the force is equal to the direction of the acceleration.

For a given force, the resulting acceleration of a body with a mass twice that of the standard mass, is half that of the acceleration of the standard mass under the influence of the same force. The conclusions are summarized in Newton's second law:' where [Sigma]F is the vector sum of all forces acting on an object with mass m, and is the resulting acceleration note: the sum includes only external forces.

The ropes make angles as shown in Figure 5. With what force must Betty pull in order to keep the tire stationary? Since the tire is stationary, the net force on the tire must be zero. This also means that the net force along the x and y direction must be zero: Substituting the known values for FA, FC and [theta] in the first equation, we can calculate [phi]: Substituting this value for [phi] into the second equation we can calculate FB: Figure 5.

Force Diagram Sample Problem Newtons Third Law If a hammer exerts a force on a nail, the nail exerts an equal but oppositely directed force on the hammer. These two forces are equal in magnitude and oppositely directed: " Note: Since the two members of an action-reaction pair always act on different bodies, they can not cancel each other. Mass and Weight The mass of a body and the weight of a body are totally different properties. The mass m of a body is a scalar; its SI unit the kilogram. The mass of a body can be determined by comparing it to the standard kilogram. Mass is an intrinsic property of a body; it is the same on the earth's surface, in an orbiting satellite, on Mars, or in interstellar space. The weight of a body is a vector; its SI unit in the Newton. The weight of a body with mass m is defined as: where g is the free-fall acceleration at the location of the body.

Since the free-fall acceleration varies from point to point, the weight of an object depends on its location, and is therefore not an intrinsic property of a body. Measuring Mass The mass of a body can be determined via comparison with the standard mass. The equal-arm balance is designed for this purpose see Figure 5. The equal-arm balance is balanced if the force on the left equals the force on the right: Figure 5. Equal-Arm Balance. Measuring Weight The measurement of the weight of an object can be carried out using a spring scale see Figure 5. The spring scale uses a spring to measure the weight of the object.

There is a one-to-one relation between the stretch of the spring and the applied force responsible for the stretch. In general, spring scales are calibrated and show the mass of the object. However, it should be stressed that the mass of the object is obtained from the measured weight, and in this process it is assumed that the free-fall acceleration equals 9. Therefore, a spring scale will only indicate the correct mass if it is used at a location at which the free-fall acceleration is equal to that at the calibration site note: a spring scale will incorrectly determine the mass of an object if it is used on the moon, or in an accelerating elevator.

Spring Scale. Applications Sample Problem Figure 5. What are the tensions in these cords? The mass m experiences a gravitational force equal to mg. Since the mass is at rest, cord C must provide an opposing force equal to mg. Applying Newton's third law, we conclude that cord C exerts a force on the knot whose magnitude is equal to mg and pointed in the direction shown in Figure 5. Since the system is at rest, the net force on the knot must be equal to zero: This vector equation can be rewritten in terms of its components along the x-axis and y-axis, using the following information: Figure 5.

Mass m on an inclined plane. In order to determine the acceleration of the block we have to determine the total force acting on the block along the inclined plane. Two forces act on the block: the gravitational force exerted by the earth on the block, and a force, called the normal force exerted by the plane on the block see Figure 5. This force must be present since in its absence mass m will experience free fall instead of sliding motion. Since the normal force is normal to the inclined plane it does not have a component along it. The component of the gravitational force along the inclined plane is given by The acceleration produced by this force can be determined from Newton's second law Figure 5.
