Question

A truck that is stopped on the road has to be pushed hard to get into motion.

When the truck is moving a little, it can be moved faster with a smaller /less

push. Why?​

Answer 1

Answer:

Because the force of pushing the truck is very less.

Answer 2

The energy needed to push an object which is in rest is required more as compared to moving object. This is the reason that a truck that is stopped on the road has to be pushes hard to get into motion whereas a truck already moving a little can be moved faster with a smaller/less push.
