What is elastic potential energy?

• The energy an object possesses due to its motion.

• The energy stored in an object due to its position in a gravitational field.

• The energy stored in an object due to its temporary deformation.

• The energy released during a chemical reaction.

What is the correct formula for elastic potential energy?

• PE_e = mgh

• PE_e = 1/2 mv^2

• PE_e = 1/2 kx^2

• PE_e = Fd

What does the spring constant (k) of a spring measure?

• The mass of the spring.

• The amount of force required to compress or expand the spring per unit length.

• The maximum displacement the spring can undergo.

• The speed at which the spring returns to its equilibrium position.
