Impulsive force and Impulse of a force
(i) Impulsive Force
An impulsive force is a very great force acting for a very short time
on a body, so that the change in the position of the body during the time
the force acts on it may be neglected.
(e.g.) The blow of a hammer, the collision of two billiard balls etc.
(ii) Impulse of a force
The impulse J of a constant force F
acting for a time t is defined as the product
of the force and time.
(i.e) Impulse = Force×time
J=F×t
The impulse of force F acting over a time interval t
is defined by the integral,
J=F∫dt (0 to t)
When a variable force acting
for a short interval of time, then the impulse can be measured as,
J = F average×dt
