For Es And Elasticity Flashcards
0
Q
How can forces be used
A
To stretch and shape objects
1
Q
Is it true that work done to an elastic object is stored as elastic potential energy
A
True
2
Q
What is an elastic objects
A
Any object that can go back to its original shape once stretched
3
Q
What has to be done to change an objects shape
A
Work done
4
Q
What happens to the potential energy when the force is removed
A
It is converted to kinetic energy
5
Q
What is hooked law
A
That the extension of a spring is directly proportional to the force applied
6
Q
What is the spring constant
A
Constant number multiplied by the extension
7
Q
What is the equation
A
F = k x e Force = spring constant x extension
8
Q
What happens when the object reaches the limit of proportionality
A
It doesn’t go back to its original shape
