Energy Conversion and Conservation

Front

What is energy conversion?

Back

Energy conversion is the process of changing energy from one form to another, such as converting chemical energy in gasoline to mechanical energy in a car engine.

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

What type of energy is produced when gasoline is burned?

Back

Chemical energy is converted into mechanical energy.

Front

How does mass affect kinetic energy?

Back

Kinetic energy increases proportionally with the mass of an object.

Front

What is sound energy?

Back

Sound energy is the energy produced by vibrating particles, which can be detected by our ears.

Front

What is nuclear energy?

Back

Nuclear energy is the energy released during nuclear reactions, such as fusion in the sun.

Front

What happens to potential energy as a roller coaster goes downhill?

Back

Potential energy is converted into kinetic energy as the roller coaster descends.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion, dependent on its mass and velocity.

Front

What is an example of mechanical energy?

Back

Mechanical energy is the sum of potential and kinetic energy in an object, such as a moving car.

Front

What is the relationship between potential energy and height?

Back

Potential energy increases with height; the higher an object is, the more potential energy it has.
