Topic 5.5-5.6: Elasticity Flashcards
1
Q
What are the two different types of deformation
A
elastic and inelastic
2
Q
what is elastic deformation
A
when the force is released the object returns back to its original shape
3
Q
what is inelastic deformation
A
when the force is released the object doesnt return to its original position
4
Q
what is extension
A
the increase in length of a springwhen stretched
5
Q
What is hookes law
(give equation)
A
the force applied to an object is directly proportional to the extension of the object when it is being elastically deformed
F=ke
6
Q
What is the equation for elastic potential energy
A
Ek=1/2ke^2
7
Q
On a graph with force plotted against extension what is the gradient of the straight line equal to
A
the spring constant
8
