1
Q
What is a tensile force?
A
A forces that stretches a spring.
2
Q
What is a compressive force?
A
A force that compresses a spring.
3
Q
What is spring constant?
A
A measure of stiffness of a spring.
4
Q
What does a large spring constant mean?
A
More force is required to stretch it.
5
Q
What is the correlation between force and extension?
A
they are directly proportional to each other.
6
Q
What is the elastic limit?
A
The point where the spring would loose elasticity if it were stretched any further.
7
Q
What is hooks law?
A
force is proportional to extension.
8
Q
What is “k” in f=kx
A
force constant.
9
Q
What does a higher gradient mean on a force extension graph?
A
higher spring stiffness.
