Dear student,
Impulse = Change in Momentum". In mathematical symbols, it can be written as:
or:
or:
ujwal reddy
THE DEFINITIONOF IMPULSE IS THE PRODUCT OF FORCE APPLIED AND THE TIME TAKEN
I=F*T
BUT F=ma
if the initial velocity pf the body is u and the final velocity of the body is v then acceleration a=v-u/t
therefore
F=m(v-u)/t
therefore substituting in the impulse equation
I=mv-mu
I=m(v-u)
THEREFORE IMPULSE IS NOTHING BUT CHANGE IN THE MOMENTUM OF THE BODY.................!!

Three identical balls are placed on a frictionless
horizontal surface touching each other. They stick to
each other because of adhesive. Another ball of same
radius and mass m is placed over the void created by
the three balls. Find the forces applied by the balls
kept on the floor to each other if the system remains
in equilibrium.
