why no force is required to move an object with constant velocity?

Answer:
A body is to be moved with a constant velocity. So, its velocity should not change.
 
When velocity does not change, acceleration is zero.
 
Now, according to Newton's second law, F = ma
 
If there is no acceleration, then there is no force required, F = m×0 = 0
 
Hence, no force is required to move an object with constant velocity.
