Question

1. when a stretched string is released, the potential energy in the string is converted to ______. (1 point)

acceleration due to gravity
work
kinetic energy
gravitational energy

Explanation:

When a stretched string is released, the potential energy (stored due to deformation) is converted. Kinetic energy is the energy of motion. As the string moves (has motion) after release, potential energy transforms into kinetic energy. Acceleration due to gravity is a constant (\(g = 9.8\ m/s^{2}\) near Earth's surface) and not an energy form. Work is the transfer of energy, not the form energy converts to here. Gravitational energy depends on height in a gravitational field, which is not relevant for a stretched - released string.

Answer:

kinetic energy
