What is the potential energy of a stretched wire?
According to Hooke’s law, the force applied to stretch the spring is directly proportional to the amount of stretch. Where, P.E = elastic potential energy and it’s expressed in Joule….The video explains how a stretched rod is analogous to a stretched spring.

What happens if a spring is stretched beyond its limit of proportionality?
Limit of proportionality Once a material has gone past its elastic limit, its deformation is said to be inelastic. The higher the spring constant, the stiffer the spring. When an elastic object is stretched beyond its limit of proportionality, the object does not return to its original length when the force is removed.
What happens to the potential energy of the spring when it is compressed or stretched?
Solution : When a spring is compressed or stretched, potential energy energy of the spring increases in both the cases. This is because work is done by us in compression as well as stretching.
When a spring is compressed by 3 cm the potential energy stored in it is u?
Final potential energy is 2U. Hope it helps.
When you compress the string is potential energy?
When string is stretched x is -ve and during compression x=+ve. In either cases, work will be done by spring to restore itself to the original shape. Hence, this Potential Energy is the work done against its restoring force.
How can you prove that the potential energy of a stretched spring turns into kinetic energy when you release the spring?
When you release a spring the velocity increases, therefore the kinetic energy increases ke=1/2*mv^2 and the displacement decreases therefore the potential energy decreases pe=1/2*kx^2.
What is the best description of the energy stored in a stretched or compressed object?
Elastic potential energy is energy stored in objects that can be stretched or compressed.
Which describes how the spring constant affects?
Which describes how the spring constant affects the potential energy of an object for a given displacement from an equilibrium position? The higher the spring constant, the greater the gravitational potential energy. The higher the spring constant, the greater the elastic potential energy.
At what point does the ball have the greatest kinetic energy?
E. 19
At what position does the car have the greatest potential energy?
When the car is at the top of the hill it has the most potential energy. If it is sitting still, it has no kinetic energy. As the car begins to roll down the hill, it loses potential energy, but gains kinetic energy.
