Impulse force time A powerful bat hitting a ball for a short time delivers a large impulse The Relationship The Principle of Impulse and Linear Momentum The crucial link is this The impulse acting on an object is equal to the change in its linear momentum This is a fundamental law in classical mechanics Mathematically its expressed as Impulse Change in Momentum This principle allows us to predict

tennis player swinging a racket to hit a ball a golfer using a club to hit a golf ball The longer the racket or club is in contact with the ball the greater the change in momentum and thus the farther the ball travels Engineering Designing safety features in vehicles like crumple zones The crumple zones increase the time interval over which the force acts in a collision reducing the impulse and therefore the change in momentum experienced by the passengers Everyday Life Pushing a shopping cart The longer you push it the greater the change in momentum and the speed at which it moves How to
