20.1 Energy Flashcard Env Sci BWHS

Front

What is kinetic energy?

Back

Kinetic energy is the energy of motion, which depends on the mass and velocity of an object.

Front

What type of energy is produced by vibrating objects?

Back

Sound energy is produced by vibrating objects and is a form of mechanical energy.

Front

What does the law of conservation of energy state?

Back

The law of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another.

Front

What is friction?

Back

Friction is the force that opposes the motion of two surfaces sliding against each other, often generating heat.

Front

What is electrical energy?

Back

Electrical energy is the energy caused by the movement of electrons through a conductor.

Front

What is mechanical energy?

Back

Mechanical energy is the sum of potential energy and kinetic energy in an object.

Front

What is thermal energy?

Back

Thermal energy is the total kinetic energy of particles in a substance, related to its temperature.

Front

What is the difference between potential energy and kinetic energy?

Back

Potential energy is stored energy based on an object's position, while kinetic energy is energy of motion.

Front

What is an example of energy transformation?

Back

An example of energy transformation is converting electrical energy into light energy in a light bulb.

Front

What is light energy?

Back

Light energy is a form of electromagnetic radiation that is visible to the human eye.
