A body, whose momentum is constant, must have constant
Force
Velocity
Acceleration
All of these
For a given mass P ∞ v. If the momentum is constant then it's velocity must have constant.
State the relation between force and acceleration. How much force acts on a body whose momentum is constant.
A body whose speed is constant
(a) must be accelerated
(b) might be accelerated
(c) has a constant velocity
(d) cannot be accelerated
Mark the correct statement(s) (1) If speed of a body is varying, its velocity must be varying and it must have non-zero acceleration.
(2) If velocity of a body is varying, its speed must be varying.
(3) A body moving with varying velocity may have constant speed.
(4) A body moving with varying speed may have constant velocity, if its direction of motion remains constant.
