The potential energy of a spring having a spring constant k stretched an amount x is
O k/(2x).
O (1/2) kx2.
O (1/2) kx.
O (1/2) k²x.
Gravitational potential energy of a particle, V, with respect to a reference point where the gravitational potential energy is zero is
calculated as:
O The product of mass, m, the velocity of the particle, v, and the height, h, above the reference point, as V- mvh.
O The product of mass, m, with the acceleration of gravity. g. divided by the height, h, above the reference point as V = mg/h.
O One half the product of mass, m, with the square of velocity, v as V,- (1/2)mv.
O The product of mass, m, the acceleration of gravity.8, and the height, h, above the reference point, as V, mgh.
