# How can you prove that a collision is not elastic? ## How can you prove that a collision is not elastic?

If objects stick together, then collisions are perfectly inelastic. If objects don’t stick together we can determine the type of collision by comparing the initial kinetic energie with the final energy. If the kinetic energy of the collision is equal, it is considered elastic.

What are examples of perfectly inelastic collisions check all that apply?

Rain sticking on a Window: A rain drop sticking to the window indicates that both cars are stuck together after a collision. This makes it an inelastic collision. Two train cars tying together: Both cars are stuck together making it an inelastic collision.

### Which are examples of perfectly inelastic collisions quizlet?

Some examples of perfectly inelastic collisions are: A person catching a ball or a meteorite hitting the earth, and two clay balls colliding. Inelastic collisions can be described as two cars colliding, changing their form and then moving independently after the collision.

What is elastic and inelastic collision give example?

For instance, collisions between billiard balls can be almost elastic but still lose some energy. A bullet hitting a target would be less elastic if it was shot at a target that is covered. The target and bullet must have the same final velocity.

## What is elastic and inelastic in physics?

A perfectly elastic collision is one that does not result in any loss of kinetic energy. Inelastic collisions are those in which some of the kinetic energy is converted to another form of energy during the collision.

What does elastic mean in physics?

Elasticity is the ability of a deformed body to return to its original size and shape after the deformation forces have been removed. This ability allows a body to respond or behave elastically.

### Is Newton’s cradle a pendulum?

Newton’s cradle, or Newton’s balls, is a device that shows conservation of momentum. It is made from a series (usually five) of pendulums that are abutting each other. Two strings of equal length are used to attach each pendulum to the frame. They are angled away from one another.

Why is it called Newton’s cradle?

The device is named after 17th-century English scientist Sir Isaac Newton. The device is also known by the names Newton’s pendulum and Newton’s balls.

## Is Newton’s cradle infinite?

In such a situation, the balls would continue swinging forever. It’s impossible to create an ideal Newton’s cradle because friction is the only force that will stop things from moving. Although air resistance can cause some friction, the majority of friction is generated within the balls.
