No force is required to move a body uniformly along a straight line. Comment.

Text Solution

Verified by Experts

The statement is true. When a body is moving uniformly along a straight line and there is no force of friction, acceleration//retardation of the body is zero i.e., `a=0` According to Newton's second law of motion, `F=ma=mxx0=0`
