Detailed Solution

The above statement is true.
Force is defined as the rate of change of momentum With respect to the time of any moving object.
Numerically, F=m×dvdt
Where F denotes force of an object having mass m moving with velocity v.
So if the object is moving with a constant velocity then it changes position with respect to time i.e. displacement in the position of the object. Constant velocity means
dvdt=0
So, F=0.
Therefore without any force the body is displaced..
