forces and elasticity Flashcards
what has to happen to change a shape of an stationary object only?
more than one force has to be applied
what is elastic deformation?
it can go back to its original shape and length after the force is gone
what is inelastic deformation?
when its original shape has been changed due to forces it cant go back
whats the equation to work out force?
force= spring constant x extension
what is stored in a elastic object stretched or compressed?
elastic potential energy store
whats the relationship between work done and elastic potential energy?
the work done is equal to the elastic potential energy stored
what equipment is used in the experiment between force and extension?
a clamp stand, 2 bosses, 2 clamps, meter ruler and weights
what does the pointer attached to the spring indicate?
the unstretched length of the spring
how do calculate the extension made by adding weights?
for each reading you subtract the stretched length from the unstreched length
what is the extension produced by 1 newton weight
4 because if its a newton weight you times by 4
