5
Q
Elastic deformation
A
Object has been stretched but returns to its original length
6
Q
Inelastic deformation
A
Object has been stretched but does not return to its original length
7
Q
Extension
A
Difference between stretched and unstretched lengths
8
Q
Limit of proportionality
A

9
Q
Elastic potential energy
A
Energy stored in a stretched or compressed spring
10
Q
