Energy Flashcard 1

Front

What is the Law of Conservation of Energy?

Back

The Law of Conservation of Energy states that energy cannot be created or destroyed, only transformed from one form to another.

Front

Give an example of the Law of Conservation of Energy.

Back

The thermal energy in an oven is transformed into chemical energy in a cookie.

Front

What is thermal energy?

Back

Thermal energy is the energy that comes from the temperature of matter. It is the total kinetic energy of particles in an object.

Front

What is the unit of energy most commonly used worldwide?

Back

Joules (J) is the standard unit of energy used in most of the world.

Front

What is the difference between high power and low power systems?

Back

High power systems produce more energy in a shorter amount of time compared to low power systems.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object due to its motion.

Front

What is potential energy?

Back

Potential energy is the stored energy of an object based on its position or state.

Front

What is radiant energy?

Back

Radiant energy is the energy of electromagnetic waves, such as light.

Front

What is the formula for calculating kinetic energy?

Back

Kinetic energy (KE) = 1/2 mv², where m is mass and v is velocity.

Front

What is the formula for calculating potential energy?

Back

Potential energy (PE) = mgh, where m is mass, g is acceleration due to gravity, and h is height.
