Question

Is a Force required to keep a body moving ?

Answer 1

According to Newton's First law, " If a body is in motion , it will remain in motion . No force required to keep a body moving."
we need a force to change the motion of a body . so if a body is at rest then we need a force to make body move.
we need a force to speed up or slow down a body.
but we don't need a force to keep the body moving with same constant velocity.
