Define Elastic Deformation

Deformation where an object returns to its original shape after the forces are removed.

2
New cards

What is the difference between elastic and plastic deformation?

Elastic is temporary (it springs back); plastic/inelastic is permanent (it stays squashed)

3
New cards

What is the equation for Hooke's Law?

F = ke (Force = spring constant * extension)

4
New cards

What does the 'Spring Constant' (k) represent?

It represents the stiffness of the material—the force required to stretch the object by one meter

5
New cards

How can you identify Hooke's Law on a graph?

By a straight line passing through the origin (the linear region).

6
New cards

What happens if you stretch a spring beyond its elastic limit?

It enters the region of inelastic deformation, meaning it will no longer return to its original shape.
