Bouncy Collision 1 A force sensor was set up behind both cars and a moving car had an elastic collision with a car at rest.
Bouncy Collision 2 A force sensor was set up behind both cars and both cars were given velocity and had an elastic collision.
Sticky Collision 1 A force sensor was set up behind both cars and a moving car had an inelastic collision with a car at rest.
Sticky Collision 2 A force sensor was set up behind both cars and both cars were given velocity and had an inelastic collision/
Explosion A force sensor was set up behind both cars, the cars were put together, and then the cars were driven apart from an internal force.

Types of Collisions
Bouncy/Elastic -- a collision in which there is no net loss in kinetic energy in the system as a result of the collision
Sticky/Inelastic -- a collision in which kinetic energy is not conserved due to the action of internal friction
Explosion -- an internal force drives the collision

Momentum
Definition |
|
Momentum can be defined as "mass in motion." All objects have mass; so if an object is moving, then it has momentum - it has its mass in motion.
Conservation of Momentum -- a principle in physics: the total linear momentum of a system of particles not acted upon by external forces is constant in magnitude and direction irrespective of any reactions among the parts of the system
Impulse |
|
Definition a force acting briefly on a body and producing a finite change of momentum.
