Question

is net force needed to keep a body moving uniform velocity

Answer 1

No, not needed.
For body to move uniformly net force MUST be zero.

Answer 2

Answer:

No , force is not needed to move the body with uniform velocity

Explanation:

According to Newton's first law of motionif a body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by a force.

This is also called the law of inertia
