5.3 - forces and elasticity Flashcards
1
Q
Explain the relationship between the force applied and the extension of an
elastic object.
A
directly proportional until the limit of proportionality is exceeded
2
Q
What is meant by an inelastic (plastic)
deformation?
A
● A deformation which results in the
object being permanently stretched
● The object doesn’t return to its original
shape when the force is removed
3
Q
What type of energy is stored in a spring
when it is stretched?
A
Elastic potential energy.
4
Q
What can extension be replaced with in
the equation for spring force?
A
Compression.
5
Q
What is meant by an elastic deformation?
A
object returns to original shape after being stretched
