Hooke's Law and Elastic Potential Energy

Which of the following is a true statement regarding springs?

• The higher the value of the spring constant, the stiffer the spring.  

• In Hooke's law, the force exerted by the spring acts in the same direction as displacement.  

• Springs are designed to provide unpredictable variations in force.  

• The force exerted by a spring has a quadratic relationship with the displacement form equilibrium.

Elastic Potential Energy is _____________________________________.

• the ability of a material to return to its original shape after it has been stretched or deformed.

• potential energy that is stored due to the deformation of an elastic object, such as a stretched spring.

• energy stored in the bonds of chemical compounds. Chemical energy is released during chemical reactions.

• the energy contained within a system that is responsible for its temperature.

• the flow of thermal energy.
