Use the spaces below to take notes on the key concepts presented in this study.
Main idea #1: If something is moving, it has momentum. Impulse is change in momentum.
The product of mass and velocity
mass*velocity
vector because it has both magnitude and direction the product of the amount of force on an object and the time during which the force is applied
F*∆t
An impulse causes change in momentum
∆p
(p=momentum)
∆p=m∆v
F∆t=m∆v
Main idea #2: In an isolated system, momentum before a collision is equal to momentum after the collision. When one object exerts a force on a second object, the second one exerts a force on the first that’s equal in strength and opposite in direction. When you have an isolated system with no external forces, the initial total momentum of the objects before the collision equals the final total momentum of the objects after the collision. Because the forces must be equal and the time the objects are in contact is the same for each object, we know that the impulse each receives is also equal.
p (1b) + p (2b) = p (1a) + p (2a)
