forces and elasticity Flashcards
(5 cards)
1
Q
What happens when forces are applied to materials?
A
Stretching, compressing, or bending transfers energy.
2
Q
What is an elastic material?
A
An elastic material returns to its original length or shape when forces are removed.
3
Q
What is an inelastic material?
A
An inelastic material doesn’t return to its original shape when forces are removed.
4
Q
How is extension related to force in inelastic materials?
A
Extension is directly proportional to force until a certain limit is reached.
5
Q
What is the elastic limit?
A
The elastic limit is the limit of proportionality, beyond which the material may not return to its original shape.
