Impulse is defined as the integral of a force acting on an
object, with respect to time. This means that impulse contains
the product of force and time. Impulse changes the
momentum of an object. As a result, a large force applied for
a short period of time can produce the same momentum
change as a small force applied for a long period of time. An
impulse can act on an object to change either its
linear momentum
,
angular momentum
,
or both.
In many real life problems involving impulse and momentum,
the impulse acting on a body consists of a large force acting
for a very short period of time – for example, a hammer strike,
or a collision between two bodies.

PRE-TEST
1. In a soccer game a player throws the ball in to play from the side line. She throws it in using her hands over her head. the ball starts from rest. The ball has a force acting in it for 0.10 seconds. On the way down the ball hits a player in the head at the same height it was thrown from. It makes contact for 0.005 seconds and comes to a rest upon contact. Which impulse is greater?
A. The throw's impulse is greater.B. The head impact's impulse is greater.C. The 2 impulses are equal.D. There is not enough information to answer the question.
2. A rocket weighing 0.3 Newtons exerts an upward thrusting force of 8 Newtons. The rocket motor fires for 0.16 seconds. Which impulse is greater during the rocket's engine firing, gravity's or the rocket motor's impulse?
3. Which has the greatest impulse?
