Forces And Elasticity Flashcards
1
Q
What is an elastic object?
A
An object that goes back to its original shape free a force has been applied
2
Q
What is elastic potential energy?
A
Work is done to change the shape of an elastic object and this energy is stored as elastic potential energy
3
Q
What happens when the force is removed?
A
The object returns to its original shape as potential energy is conveyed to kinetic energy
4
Q
What does Hooke’s law state?
A
The extension of a spring is directly proportional to the force applied
5
Q
What is the equation for this?
A
F=k x e
6
Q
What is k?
A
The spring constant measured in N/m (found by gradient)
7
Q
What happens when a object is stretched beyond its elastic limit?
A
It no longer obeys hookes law and will not retain its original shape (limit of proportionality)
