1. Momentum and Impulse Theorem By Corina Bot

2. Momentum can be defined as "mass in motion." All objects have mass  if an object is moving, then it has momentum  it has its mass in motion. Examples: air bags in automobiles. Air bags are used in automobiles because they are able to minimize the affect of the force on an object involved in a collision. Air bags accomplish this by extending the time required to stop the momentum of the driver and passenger.

3. A car is traveling at a velocity of 20 m/s on a straight road. Mass of the car is 1300 kg. A motorcycle passes the car at a speed of 40 m/s. The motorcycle with its rider has a mass of 370kg. Which one has a higher momentum? Why ? For the car: For the motorcycle and rider: The car has more momentum than the motorcycle even though its velocity is half.

4. Impulse = Change in momentum When a force is applied to a rigid body it changes the momentum of that body. www.sciencemuseum.org.uk http://www.salk.edu/ Momentum examples video
