turning on a battery - operated light

a child going down a slide on a playground

using a gas power heater to warm a room

rubbing your hands together to warm them on a cold day

using a hand - crank generator to produce electric current

using the light in your room that is plugged into the wall

a boy shooting a rubber band across the classroom

using a dc electric motor

Explanation:

• Chemical potential energy transformed into radiant energy: A battery - operated light uses chemical energy (stored in the battery) and converts it to radiant energy (light).
• Gravitational potential energy transformed into kinetic energy: A child going down a slide has gravitational potential energy (due to height) which is converted to kinetic energy (motion).
• Elastic potential energy transformed into kinetic energy: A boy shooting a rubber band has elastic potential energy (stored in the stretched rubber band) which is converted to kinetic energy (motion of the rubber band).
• Chemical potential energy transformed into thermal energy: Using a gas power heater, the chemical energy in gas is converted to thermal energy (heat).
• Electrical energy transformed into radiant energy: Using the light in your room that is plugged into the wall, electrical energy is converted to radiant energy (light).
• Kinetic energy being transformed into thermal energy: Rubbing your hands together, the kinetic energy of hand - motion is converted to thermal energy (heat).
• Electrical energy transformed into kinetic energy: Using a dc electric motor, electrical energy is converted to kinetic energy (rotational motion of the motor).
• Kinetic energy transformed into electric energy: Using a hand - crank generator, the kinetic energy of cranking is converted to electric energy.
