Rockets: Force and Motion

Author(s): Gregory L. Vogt, EdD

Equal Forces: Different Results

The same force exerted on different objects can produce different results. In this case the same force is applied to an elephant and a mouse. The mouse has less mass so it had less inertia. The mouse’s inertia is easier to overcome and it moves a greater distance than the elephant. Because of the elephant’s large inertia, it is harder to start moving, but also harder to stop once it gets going.
