Physics is the study of matter and energy. This branch of science comes with its own specific vocabulary. Do you remember these physics words from high school?

# A positively charged particle.

A proton is a positively charged particle. An electron is a negatively charged particle.

# Light but no heat.

Luminescence is the emission of light but not heat. The word has Latin roots.

# A stability of forces.

Equilibrium is the stability of physical forces. The universe is always seeking a state of equilibrium.

# The process of bending light.

Refraction is the process of bending light. In physics, light bends around objects.

# A rate of increase.

Acceleration is a rate of increase. In physics, this refers to velocity.

# A basic unit of electricity.

An ampere is a basic unit of electric current. We laymen just cal them "amps."

# The smallest part of an element.

Atoms make up elements. Atoms are made of protons, neutrons and electrons.

# A rod that helps a wheel rotate.

An axle is a component of wheel movement. Axles are rods, poles and/or shafts.

# A unit of heat.

A calorie is a unit of heat. One calorie raises the temperature of one gram of water one degree Celsius.

# An electrical path.

A circuit is a path that allows the flow of electricity. Break the circuit and the flow of electricity stops.

# A physical attribute conveyed by light.

Color is a physical attribute determined by light. Light can be emitted, transmitted or reflected.

# To transmit.

Conduct is another word for transmit. Iron conducts heat.

# Retention of certain qualities.

Conservation is a retention of certain qualities. In physics, these qualities may be physical or chemical.

# A transformation.

Conversion is a transformation or change. For example, glycogen may convert to glucose.

# A physical resistance to motion.

Drag is a physical resistance to motion. Wind and fluids can cause drag.

Elasticity is the tendency of an object to return to its original shape. Rubber bands are elastic.

# A negatively charged particle.

An electron is a negatively charged particle. Electrons orbit atoms.

# The application of stress on an object.

Force is the application of stress on an object that causes motion. Force is a physical motion.

# The application of resistance.

Friction occurs when two objects meet. These two objects create resistance.

# A wheel with teeth.

A gear is a wheel with teeth. A rotating gear engages with another toothed object to create motion.

# The force of attraction.

Gravity is a force of attraction between everything in the universe. Degrees of gravity vary.

# A form of energy.

Heat is a form of energy. Heat is transferred via conduction, convection or radiation.

# A unit of frequency.

Hertz is a unit of frequency. It is also a car rental company, but that has nothing to do with physics.

# Wave displacement.

Amplitude is the displacement of a periodic wave. In physics, this often refers to oscillation or vibration.

# A collision between two or more objects.

An impact occurs when two or more objects collide. Used in physics, this word is a noun.

# Something at rest or lacking motion.

Something that is at rest is inert. Isaac Newton said that an object at rest would stay at rest.

# A level of energy.

Intensity is a measurable level of energy. Intensity may vary.

# A particle that is positive or negative.

An ion is a negatively or positively charged particle. The charge of the particle is electric.

# A force that opposes gravity.

Lift is a force that opposes gravity. This force is applied in aerodynamics.

# Having weight and occupying space.

Mass has weight and occupies space. The mass of an object can be measured.

# Having no electrical charge.

Something that has no electrical charge is neutral. Electrical charges may be positive or negative.

# A small object with mass.

A particle is a small object that has mass but limited dimensions. The mass of a particle is finite.

# The connection of at least two bodies.

A collision is a physical meeting of at least two bodies. In physics, energy is exchanged via collisions.
