Spring Potential Energy

The potential energy is the energy possessed by a body by virtue of its position or the energy held by the object due to its position relative to other objects, its force like stresses, charge, and other factors affecting the particles of the body. The potential energy is the measure of the net work done by or on the body. The spring potential energy is the potential energy stored due to the deformation of an elastic spring and this elasticity is due to the stretched spring. The elasticity is the ability of a solid-state matter to come back to its equilibrium position or original position after any kind of external force is acted on it. It is also known as Elastic potential energy. The potential energy here is caused due to the displacement of the spring from its equilibrium position to another position and this potential energy is equal to the net work done due to the stretching of the spring. It also resembles the same mechanics of the oscillation of a simple pendulum, where due to the external force, the object moves from its equilibrium position to its maximum ends and the periodic motion continues till it comes back to the equilibrium position to rest.

A box of mass m is pressed against (but is not attached to) an ideal spring of force constant k,
compressing the spring a distance x. After it is released, the box slides up a frictionless incline (as
shown above) and eventually stops.
If we repeat this experiment but instead use a spring having force constant 2k:
Choose as many as apply.
Just as it moves free of the spring, the speed of the box will be √2 times as great as before.
Just as it moves free of the spring, the kinetic energy of the box will be twice as great as before.
The box will go up the incline twice as high as before.
