Question

6. When a constant force is applied to a body moving with the constant acceleration, is the power
of the force constant? If not, how would force have to vary with speed for power to be
constant​

Answer 1

Answer:

If body is moving with constant acceleration, according to F= ma , the net force on the body is constant. Now Power: Power, P= F.v. In one dimension, P=Fv. As F is constant and because of acceleration v is not constant power will not be constant
