Answer 1

Answer:

Explanation:

This is because at  first the body remains in a state of rest. In order to break its state of rest, a larger force is required to bring the body under a state of motion. When the body moves, the body acquires linear momentum. The linear momentum allows it to gain a force there it is easier to move the body once it is in motion.
