Question

Which of the following is an example of a net force? A. A 10 kg box of books has inertia. B. A car travels at a constant velocity of 10 m/s. C. Friction pushes against an object, slowing it down. D. A car in motion will tend to stay in motion, while a car at rest will tend to stay at rest.

Answer 1

I think the correct answer from the choices would be that a car in motion will tend to stay in motion, while a car at rest will tend to stay at rest. Net force is the sum of all of the forces that are acting on an object. So, if the sum of the forces is zero then the object is at rest while if it is a value, then it is moving.
