How do you turn elastic energy into kinetic energy?
I need a way to calculate the elastic energy of a spring and a formula to find its kinetic energy as it returns to its original position after being stetched. Is there a way to find the rate (velocity) at which a spring contracts? Please show all workings, calculations, and formulas.
Answer:
Spring Potential Energy, U = (1/2)kx^2, where k is the spring constant and x is the displacement from rest position
U = KE, if we can assume no loss to friction.
KE = (1/2) mv^2, where m is the mass of the object attached at the end of the string, and v is its velocity
