Question

Force acting on the particle moving with constant speed is _____

a) always zero b) need not be zero

c) always not zero d) cannot be concluded​

Answer 1

Answer:

If a particle has a constant velocity, it also has a constant momentum. Thus, if an object is moving with a constant momentum, the vector sum of the forces acting on it equals zero. If the net force on an object is not equal to zero, then the object will not move with a constant momentum (or velocity).

Answer 2

Answer:

Force acting on the particle moving with constant speed is _always zero____
