Energy concepts Flashcards
1
Q
What is hookes law?
A
The extension of the spring is directly proportinal to the tension, provided the elastic limit is not exceeded
2
Q
What is the elastic limit?
A
Where the material does not reurn to its original shape when the load is removed.
3
Q
What happens when the elatic limit is exceeded?
A
Plastic deformation occurs (material does not return to original shape)
4
Q
What is elastic deformation?
A
Energy possessed by an object by virtue of its deformation
5
Q
What is dissipative force?
A
Forces which lead to a loss in mechanical energy in a system, e.g dynamic friction
