What is the difference between elastic and Inelastic Collisions?

Elastic collisions
Elastic and inelastic collisions are two classes of force. Elastic collisions are when there is no kinetic energy loosed in the event of the collision which causes the object to bounce, or fall back based on what the base is. Inelastic collisions are when all of the kinetic energy is lost which causes the object to splat, or stay on the ground.

This ball shows a good example of elastic energy. wszqs.png

Elastic collisions
A car collision is another good example of inelastic and elastic forces. In an inelastic car collision, two cars crash together, causing one of the cars to push the other in its direction. If it was an elastic collision, the cars would bounce away in two completely different directions. This picture is an example as an inelastic collision. If the cars crashed together and completely come to a stop; that would be also an example of an inelastic collision because the amount of force that is lost, is even with its collision.

Isaac Newton
Isaac Newton was a very good and resourceful physicist. He was born on Christmas day 1642, and died March 20th 1727. He was the master mind of all physics. One of his first theories was the 3 laws of motion:
First law: The velocity of a body remains constant unless the body is acted upon by an external force.
Second law: The acceleration of an object is parallel and proportional to force and is opposite to the mass.
Third law: For every action there is an equal and opposite reaction.
Isaac Newton tested a lot of theories to physics. We thank him today for all he has done. For example, newton's cradle, an apple falling on his head which leads to gravity, and the reflecting telescope in 1668.

Here is a website where you can test elastic and inelastic collisions.
When a carousel is spinning, think about putting weights on the sides of the carousel, and spin the carousel really fast. That is an example of gravity,and elastic forces, because the kinetic force is pulled through the weights causing it to go up. car.png this is a picture of a virtual carousel
