What is the definition of gravitational energy?

• Gravitational energy is not a type of energy.

• Gravitational energy creates heat to warm up the surface of the Earth.

• Gravitational energy is the energy an object has because of its position above a surface.

• Gravitational energy is the energy an object does not have because of its position below the surface.

What is the definition of light energy?

• Light energy is the energy that is visible to the human eye.

• Light energy is the energy that can only be seen in complete darkness.
• Light energy is the energy produced by sound waves.
• Light energy is the energy stored in chemical bonds.

What is the definition of nuclear energy?

• Nuclear energy is the energy generated by wind turbines.
• Nuclear energy is the energy harnessed from solar power.
• Nuclear energy is the energy stored in the centre of the particles that make up matter.

• Nuclear energy is the energy produced by chemical reactions.

What is the definition of potential energy?

• Potential energy is the energy of motion. It is being used the whole time.

• Potential energy is the energy released during a chemical reaction.
• Potential energy is the energy associated with thermal motion.
• Potential energy is the energy an object has because of its position or condition. It has not been used yet.

What is the definition of thermal energy?

• Thermal energy looks like a thermos full of soup.

• Thermal is another term for heat energy.

• Thermal energy is the potential energy of an object due to its position.
• Thermal is another term for cold energy.

What is the definition of elastic energy?

• Elastic energy is the energy caused by the stretching or pushing together of some materials.

• Elastic energy is the energy caused by the squishing or snapping together of some materials.

• Elastics are not forms of energy, they are only used to make a ponytail.

• Elastic energy is the energy produced by heat.

What is the definition of kinetic energy?

• Kinetic energy of not moving. When an object is not moving, it has kinetic energy.

• Kinetic energy is a game you play where you join different pieces together.

• Kinetic energy is the energy that has potential. When an object creates heat it has kinetic energy.

• Kinetic energy is the energy of movement. When an object is moving, it has kinetic energy.

What is the definition of electrical energy?

• Electrical energy only works the best to create darkness.

• Electrical energy is the energy of charged particles.

• Electrical energy is the energy of only charged batteries.

• Electrical energy has the same definition as chemical energy.

What is mechanical energy?

• Mechanical energy (kinetic energy or potential energy) is the energy of either an object in motion or the energy that is stored in objects by their position.

• Mechanical energy is a machine.

• Mechanical energy (kinetic or thermal energy) is the energy of an object in motion or stored by their position.

• Mechanical energy is the energy that can be streched or pulled.

What is sound energy?

• Sound energy is the same a light energy.

• Sound energy is the energy that happens when objects do not vibrate. Objects that do not vibrate make lower and higher sounds.

• Sound energy is the energy that happens when objects vibrate. Objects that vibrate slowly have lower sounds, and objects that vibrate faster have higher sounds.

• Sound energy is about vibrations, but only in musical instruments.
