Momentum
|
A vector quantity defined as the product of an object's mass and velocity.
|
|
Impulse
|
The product of the force and the time over which it acts on an object.
|
|
Difference between Momentum and Impulse.
|
Momentum is what the object has and Impulse is whats done to cause change.
|
|
Law of Conservation of Momentum.
|
The total momentum of all objects interacting with one another remains constant reguardless of the nature of the forces between them.
|
|
Perfectly inelastic collisions
|
Two objects stick together and move as one mass after the collision. Momentum is conserved but kinetic energy is not conserved.
|
|
Inelastic Collisions
|
Colliding objects bounce and move separately after the collision, but the total kinetic energy decreases in the collision.
|
|
Elastic Collisions
|
Two objects return to thier original shapes and move away from the collision separatly. Both momentum and KE are conserved.
|
|
Most types of collisions are?
|
Inelastic
|
