What is elastic limit?

Back

The elastic limit is the maximum extent to which a solid can be stretched without permanent deformation.

Front

What happens to an object when it exceeds its elastic limit?

Back

It undergoes permanent deformation.

Front

What is the relationship between speed and kinetic energy?

Back

Kinetic energy increases with the square of the speed.
