1. Collisions
Ms. Jeffrey- Physics

2. Collisions
An interaction between two objects that have made contact with each other
A force is applied to the two colliding objects
The forces are equal and opposite
Causes one object to slow down (lose momentum), and the other object to speed up (gain momentum)

3. Acceleration in a collision
The force during a collision is equal and opposite
If the masses of the objects in the collision are unequal, then the acceleration of the objects will be unequal
The smaller mass in the collision will have a greater acceleration
The larger mass in the collision will have a smaller acceleration

4. Momentum Collision Principle
During a collision, the total momentum before a collision is equal to the total momentum after the collision
The momentum lost by one object, is gained by the other object.
MOMENTUM IS CONSERVED
Momentum before collision = Momentum after collision
Initial momentum = final momentum
m1iv1i+ m2iv2i = m1fv1f + m2fv2f

5. Elastic and Inelastic Collisions
Momentum and energy is conserved
The two objects bounce off each other
Inelastic Collisions
Momentum is conserved, but energy is not
The two objects stick together, and move as one
