Energy Unit Study Guide (SOL 5.2)

Vocabulary flashcards covering forms of energy, energy transformations, work, and the law of conservation of energy based on SOL 5.2.

Energy

The ability to do work or to cause change.

Potential Energy

Energy that is stored.

Kinetic Energy

Energy being used.

Motion (Mechanical Energy)

Energy involved in movement; examples include a bicycle moving, a person running, or a windmill turning.

Light (Radiant Energy)

Energy from light sources such as the sun, fire, stars, and light bulbs.

Sound

Vibrations that can be heard.

Electrical Energy

Energy where wires and batteries turn electrical energy into other forms; natural forms include lightning and static electricity.

Magnetic Fields

Magnetic force fields created around magnetic objects such as electromagnets.

Heat (Thermal Energy)

Thermal energy associated with heat; examples include an oven, hair dryer, or toaster.

Chemical Energy

Energy stored in chemical bonds; examples include digesting food, gas in a car, or burning wood for heat.

Work

A force acting upon an object, causing that object to move in the direction of the force.

Conservation of Energy

The law stating that energy can change forms but cannot be created or destroyed.

Solar Power Transformation

The transformation of light energy into electricity using solar panels.

Hydroelectric Power Transformation

The transformation of mechanical energy from water into electricity using dams.

Wind Energy Transformation

The transformation of mechanical energy from wind into electricity using wind turbines.

Steam Engine Transformation

The conversion of thermal energy into mechanical energy.

Energy Transformation

The process where energy changes from one form to another to do work.
