Energy

Conservation of Energy

• Energy can be created and destroyed.

• Energy can be transformed from one form to another.

• According to the Law of Conservation of Energy, energy cannot be created nor destroyed.

• Energy is only found in living organisms.

MATTER

• The physical substance that has mass and occupies space, made of atoms.

• A concept in physics that describes energy and its transformations.

• A type of chemical reaction that involves the rearrangement of atoms.

• A theoretical construct that explains the behavior of light.

Calorie

• A calorie (cal) tells you how much energy is needed to raise 1 gram of water 1°C, also called “small calorie”

• A calorie (cal) is a unit of weight measurement.

• A calorie (cal) is the amount of energy required to freeze 1 gram of water.

• A calorie (cal) is a measure of temperature.

MECHANICAL ENERGY

• Energy that an object has due to its motion or position; used to lift, move or hold objects.

• Energy stored in chemical bonds of molecules.

• Energy that is transferred through heat.

• Energy that is associated with the gravitational field.

Power

• The total energy consumed over a period of time

• The rate at which energy is used

• The maximum energy that can be consumed

• The energy required to perform work

Electrical Energy

• Energy carried by charged particles, also called electricity.

• A type of energy that cannot be converted into other forms.

• Energy that is stored in the nucleus of an atom.

• Energy produced by chemical reactions.

Light Energy

• Energy carried by sound waves

• Energy carried by light or electromagnetic radiation

• Energy stored in chemical bonds

• Energy produced by nuclear reactions

NUCLEAR ENERGY

• Energy that holds atoms together and can be released during nuclear reactions

• Energy derived from fossil fuels

• Energy produced by solar panels

• Energy generated by wind turbines

Energy Transformation

• The process of creating energy from nothing

• The conversion of energy from one form to another

• The storage of energy in batteries

• The measurement of energy in joules

WORK

• Applying a force to move or change something.

• A state of inactivity or rest.

• A type of energy that cannot be created or destroyed.

• The process of learning new skills.
