Momentum Flashcards
Momentum equation
Mass X velocity
Conservation of momentum
In a close system the total momentum before an event is equal to the total momentum after the event.
Examples of momentum with collisions
Objects will either collide and move in opposite directions - elastic collision
Or collide and move in same direction together - in elastic
What happens if objects are moving in same direction together
Combined mass and velocity
Tips for full makes
Consider motion before and after and state velocities of each object and the direction each object moves. State whether elastic or inelasric - elastic - KE is same before and after, in elastic- two objects stick together
Describe energy transfers if KE not conserved
