Energy is something that is in motion for example kinetic means something in motion and its also an energy type. Potential energy is stored energy. Energy is the ability to do work. An object that has energy can perform work.

# data[].attributes.body
Work is something that uses effort and energy which uses time to make something. Work is applying a force to move or change something. Therefore, something that has energy can apply a force. For example, pushing or pulling an object is work.

It states that energy can not be created or destroyed. Total energy of an isolated system remains constant. Energy can change forms, but the total amount of energy remains the same. For example, an ice cube could melt to water. Either way the ice cube or water are the same amount.

# data[].attributes.body
Yes, energy can change. Energy can never be destroyed, but it can change forms. Energy can change from potential to kinetic like when a person is on a swing, when they go up it is potential and when they go down it is kinetic. Potential energy is stored energy and kinetic energy is energy in motion.

Energy can never by created or destroyed because of the law of conservation of energy. Total energy of an isolated system remains constant. When a lamp is turned on the light turns on and light energy is transferred from the electrical energy from the outlet the lamp is plugged into. Just because the lamp is turned off does not mean the light energy is gone, it is just changed back into electrical energy.

3. Can an object transfer more than one type of energy?

3. Can an object transfer more than one type of energy?

# data[].attributes.body
Yes, an object can transfer more than one type of energy. In the PhET lab you can see that the sun which is light energy can transfer to solar panels which transfer electrical energy and goes to heat up water that gives off thermal energy. Or when you flip a switch to turn on the light you transfer electrical energy from the outlet to the light which gives off light energy and also thermal energy.

Light energy from the sun is used to power food chains. The sun's light energy is used by plants to make food and build plant parts. Animals eat plants. Other animals eat the animals that eat the plants. Like a circle of life.

# data[].attributes.body
Energy stored within the bonds between the atoms of matter. The bonds between atoms in food and fuel store a lot of chemical energy.  When a person digests food, the bonds break and chemical energy is released. When fuel is burned, the bonds break and chemical energy is released.

Energy carried by light. It is visible to the human eye. It is electromagnetic radiation. Light energy is also called radiant energy.

# data[].attributes.body
Associated with temperature. Matter is made of atoms. Atoms are always vibrating. Atoms vibrate faster at higher temperatures. A hot object has more energy than a cold object.

# data[].attributes.body
Energy that is carried by sound waves. Sound waves moves when something vibrates and carries the sound. Sound energy can travel through all matter solid, liquid and gas. Sound waves travel longitudinal.

# data[].attributes.body
Energy that is carried by charged particles. Electricity is something that you use for a microwave or TV when it is plugged into a circuit and being used. Static Electricity is charged particles that are stored electrical energy and that is built up on an object. Current Electricity is charged particles that move from one place to another and are moving electrical energy.

Energy that an object has due to its motion or position. A hammer has mechanical energy because it moves to hammer a nail. Wind has mechanical energy because it is moving air.
