Question

The symbol and formula for momentum is
(A) m, pv
(B) p, ma
(C) p, mv
(D) M, mv

Answer 1

Hint: The momentum of a body depends upon its mass and velocity. Hence the body which has higher mass or velocity will have greater value of momentum. The momentum has the same direction as velocity since it directly depends on velocity. Momentum can also be described as a type of speed or force of a moving object.

Formula used:
p=mv
where, p is the momentum
m is the mass
v is the velocity

Complete step by step solution:
The momentum of a body depends upon its mass and velocity. Hence the body which has higher mass or velocity will have greater value of momentum. Thus momentum of a particle may be explained as the product of the mass of the body and its velocity.
According to Newton’s second law of motion force is proportional to the acceleration. Or otherwise, change in momentum is equal to impulse. Where impulse is the product of force and time. For a rigid body the total momentum of the body will be the sum of individual moments of particles. Since, velocity is a vector quantity the momentum is also a vector quantity. That is, which have both magnitude as well as direction. The momentum has the same direction as velocity since it directly depends on velocity. Momentum can also be described as a type of speed or force of a moving object. Whereas, the inertia is the tendency of an object to move on. Thus all the moving objects will have a momentum. The momentum of a body depends upon its mass and velocity. Hence the body which has higher mass or velocity will have greater value of momentum. Thus momentum of a particle may be explained as the product of its mass and velocity.

So, the correct answer is “Option C”.

Note: The momentum of a body depends upon its mass and velocity. Hence the body which has higher mass or velocity will have greater value of momentum. Thus momentum of a particle may be explained as the product of the mass of the body and its velocity. For a rigid body the total momentum of the body will be the sum of individual moments of particles.
