Question

A body is acted upon by a constant force, then it will have a uniform

• A. speed
• B. velocity
• C. momentum
• D. accleration

Answer 1

Answer: (D)

accleration

Let a constant force $F$ acts on the object.Then its acceleration will be a constant $i.e.$ $\frac{F}{m}$.We cannot say that the body will have uniform momentum,velocity,speed.Momentum will change as $F=\frac{dP}{dt}$,and hence velocity and speed changes.
