Energy Vocabulary FLASH CARD VERSION - Savvas 2025

Energy

• The ability to do work or cause change.

• A measure of temperature.

• A type of force that acts on objects.

• A form of matter that can be seen.

Energy in Everyday Life

• Energy changes and conservation occur in everyday activities, like riding a bike, cooking food, and using a flashlight.

• Energy is only relevant in scientific experiments and not in daily life.

• Energy can be created and destroyed in everyday activities.

• Energy is only used when we are exercising or doing physical activities.

Speed and Kinetic Energy

• The speed of an object has no effect on its kinetic energy.

• The faster an object moves, the more kinetic energy it has.

• Kinetic energy is only dependent on mass, not speed.

• Kinetic energy decreases as speed increases.

Electromagnetic Radiation

• Energy that travels through space as waves

• A type of sound wave

• A form of mechanical energy

• Energy that requires a medium to travel

Height and Gravitational Potential Energy

• The height of an object does not affect its gravitational potential energy.

• The higher the object, the less potential energy it stores due to gravity.

• The height of an object affects its gravitational potential energy, with higher objects storing more potential energy due to gravity.

• Gravitational potential energy is only affected by the mass of the object, not its height.

Work-Energy Principle

• The work done on an object is equal to the change in its kinetic energy.

• The total energy of an isolated system remains constant over time.

• Work is defined as the force applied to an object multiplied by the distance it moves.

• Energy cannot be created or destroyed, only transformed from one form to another.

Law of Conservation of Energy

• Energy can be created and destroyed.

• The total amount of energy in a closed system remains constant.

• Energy can only be created, not destroyed.

• Energy can change forms but not be conserved.

Conservation of Energy

• Energy can be created and destroyed.

• Energy can only be transferred or transformed.

• Energy can be created but not destroyed.

• Energy is always lost in transformations.

Energy Conversion

• The process of changing one form of energy into another.

• The process of creating energy from nothing.

• The process of storing energy for future use.

• The process of measuring energy in different units.

Heat Loss in Energy Transfer

• Energy is always fully converted during transformations.

• Some energy is often lost as heat, which is less useful for doing work.

• Energy transformations do not involve any loss of energy.

• Heat loss increases the efficiency of energy transfer.
