New cards

what is Hookes law?

The extension of an elastic object is directly proportional to the force applied

2
New cards

What is extension?

Final length - original length

3
New cards

What is Elastic Limit?

A point at which the material will no longer behave elastically

4
New cards

What is Elastic Deformation?

When the object will return to its original shape when force is removed

5
New cards

What is inelastic deformation?

When an object will not return to its original shape once force is removed

6
New cards

What is the limit of proportionality?

The point after which force and extension are no longer proportional

7
New cards

What is Elastic Potential Energy?

The energy store pd in a stretched or compressed material

8
New cards

Tells you the amount of force needed per unit length to stretch or compress a material
