The toy on a spring illustrated energy conversion among what different forms? the toy on a spring illustrated energy conversion among what different forms? kinetic energy, elastic potential energy, and thermal energy gravitational potential energy, kinetic energy, and thermal energy gravitational potential energy and thermal energy kinetic energy and elastic potential energy gravitational potential energy, kinetic energy, and elastic potential energy

The correct answer is:

between kinetic energy and elastic potential energy.

In fact, the total mechanical energy of the system is given by:

where

is the elastic potential energy, with k being the spring constant and x being the compression/stretching of the spring, and

is the kinetic energy, with m being the mass of the toy and v being its speed.

When the spring is compressed, the elastic potential energy U is maximum (since x is maximum), and the kinetic energy is zero(since the speed is zero). As the spring is released, the elastic potential energy U decreases (because x decreases), and the kinetic energy K increases (since the speed of the toy v increases).
