This is an wind up toy. The wind up toy has a metal clip on its back that can be wound up. As the clip unwinds, it moves the legs and arms, causing the toy to move forward. How does this demonstrate transfer of energy?

• The winding of the clip is mechanical energy and as it is moving the toy, it causes additional mechanical energy.

• The winding of the clip is mechanical energy and the movement of the toy caues thermal energy

• The movement of the root is mechanical energy and the winding of the toy uses electrical energy

• As the clip moves it causes mechanical energy and the legs and arms move because of sound energy from the clip

A student placed a beaker on top of a hotplate. The arrow placed on the beaker demonstrates the movement of the liquid caused by the energy produced by the beaker. How does the energy produced by the beaker affect the movement of the substance.

• The decreased energy produced from the hotplate is causing the substance to move rapidly

• The increased energy produced from the beaker is causing the substance to move less rapidly.

• The increased energy produced from the hotplate is causing the substance to move rapidly

• The increased energy produced from the hotplate is circulating throughout the beaker causing the substance to heat up throughout
