Vedclass · Answer

(A) When a coil spring is compressed,an external force is applied to displace the spring from its equilibrium position.According to the work-energy theorem,the work done on the spring by the external force is stored within the spring in the form of elastic potential energy.The formula for elastic potential energy is $U = \frac{1}{2}kx^2$,where $k$ is the spring constant and $x$ is the displacement.As the spring is compressed,the displacement $x$ increases,which leads to an increase in the elastic potential energy stored in the spring.

When a coil spring is compressed,the work is done on the spring. The elastic potential energy:
