Question

(a) Joseph was pushing a car.On his observation found that it was easier to keep the car in moti with a smaller force than to start its motion. Explain why?​

Answer 1

Newton's laws states that 'what is in motion, stays in motion until a external force is applied', when a car is already moving, it's in motion already but to start a car, you need to apply some force to get it going, that force isn't required for a moving car.
