forces and elacsticity Flashcards
1
Q
what is the extension?
A
the increase of length from the original
2
Q
what is the elastic limit?
A
When an object does not return to its original length when the force is removed. In this instance, the relationship between force and extension changes from being linear to being non-linear.
3
Q
what is hooke’s law?
A
the extension of a spring is directly proportional to the force applied, as long as the limit of proportionality (elastic limit) is not exceeded
4
Q
what is the hooke’s law equation?
A
force applied, F (N) = spring constant, k (N/m) x extension, e (m) - (obvs this equation can be rearranged)
5
Q
the stiffer the sping is…
A
the greater the spring constant
