Which factor affects gravitational potential energy but not elastic potential energy?

• spring constant

• velocity

• distance

• mass

Which factor affects elastic potential energy but not gravitational potential energy?

• spring constant

• acceleration due to gravity

• distance from a given position

• amount of matter in the object

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 lower the spring constant, the greater the gravitational potential energy.

• The higher the spring constant, the greater the elastic potential energy.

• The lower the spring constant, the greater the elastic potential energy.
