Forces and Elasticity Flashcards
1
Q
What happens when you stretch a spring?
A
You have done work on the spring
2
Q
What does “work” mean?
A
To transfer energy
3
Q
Using the definition of work what has happened to the spring once one have stretched it?
A
Transferred energy to the spring a stored the energy as elastic potential energy
4
Q
What is Hooke’s Law?
A
The extension of an object is directly proportional to the force applied, provided the limit of proportionality is not exceeded
5
Q
What is direction proportion?
A
You double the force you, double the extension
6
Q
What is the formula for force?
A
F = k x e force = spring constant x extension
7
Q
What is spring constant measured in?
A
N/m
