physics Flashcards
The relationship between the spring force magnitude and displacement magnitude
directly proportional relationship whether in compression or in stretching from the equilibrium point where spring force is always in the opposite direction of the displacement
the relationship between the spring force and the external force
equal to each other
equilibrium spring point
where the spring is nor compressed or stretched
the spring force points towards
equilibrium point
Hooke’s law
fs = -k(x-xi) if we assumed that the equilibrium is xi=0
then
fs=-kx
the k sign
positive
the negative sign in HOOKE’S law
K is always positive, yet the sign to indicate that the spring force is always opposite to the displacement.
Hooke’s law limits
when the spring exceeds the elastic limits then it wount try to go back to equilibrium, since Hooke’s law is based on that information then it is not valid at this case
N\m
the amount of force needed to compress or to stretch the spring for 1 meter. which is the spring force unit
restoring force
the force that tries to get the spring to the equilibrium position which is the spring force
adding weight
adding weight to a spring will only shift the equilibrium position
spring work done law
memories it
spring work done sign
always negative to the displacement
the spring mass is
massless
