17
Q

What is elastic deformation?

A

It can go back to its original shape and length after the force has been removed. They’re called elastic.

18
Q

What is inelastic deformation?

A

If the force doesn’t return to its original shape after the force has been removed

19
Q

How do you work out force?

A

Spring constant x extension

20
Q
