Answer:
Momentum
The quantity of motion possessed by a moving body is known as momentum of the
body. (1)
Momentum of an object of mass m moving with a velocity v.
Momentum, p = mv
Its SI unit is (1)
Force applied on an object of mass m moving with acceleration
a.
( Acceleration = Rate of
change of velocity )
(1)
Force applied on an object
is equal to the rate of change of momentum of the object.
(i) Momentum versus velocity graph when mass is fixed.
Momentum versus velocity
graph will be a straight line passing through the origin (If y = 0, then p = 0).
(1)
(ii) Momentum versus mass graph when velocity is constant.
p = mv
If velocity is constant, then
So, the momentum versus mass graph will be a straight line
passing through the origin (if m = 0. Then p = 0). (1)
