Read the passage below and answer the question <br><br>
In considering the effect of force on motion, linear momentum is very important. This can be understood from the following examples:<br><br>
1. We know that a much greater force is required to push a truck than a car to bring them to the same speed in the same time. Similarly a greater opposing force is needed to stop a heavy body than a light body in the same time, when they are moving with the same speed. Thus the mass of a body is an important parameter that determines the effect of force in its motion.<br>
2. Speed is another parameter to consider. A bullet fired from a gun can easily pierce through a target like human tissue, before it stops, resulting in grave injury. The same bullet thrown at a moderate speed can be easily stopped. Thus for a given mass, greater is the speed, greater is the opposing force needed to stop the body in a certain time. <br><br>
