Physics 1.1.5 Flashcards
1
Q
Energy in the Elastic Potential Energy Store of an object is defined as:
A
The Energy Stored in an Elastic object when Work is Done on the object.
2
Q
What happens to the EPE Store of a Spring when it is Stretched/ Compressed?
A
Work is Done on it, which results in Energy being Transferred to the EPE Store.
3
Q
What happens to the EPE Store of a Spring when it is Released?
A
Energy is Transferred away from its EPE Store.
4
Q
EPE = …
A
Spring Constant X Extension^2 /2
5
Q
What is the ‘Spring Constant’?
A
The stiffness of the Spring.
6
Q
Force = …
A
Spring Constant X Extension
7
Q
How do you work out the Extension of a Spring?
A
New Length - Original Length.
