Energy Transformations

Front

What is energy transformation?

Back

Energy transformation is the process of changing energy from one form to another, such as converting electrical energy into 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

Give an example of energy transformation in a bicycle when using brakes.

Back

When Kai uses the brakes on his bicycle, kinetic energy is transformed into thermal energy due to friction.

Front

What type of energy is produced by a ringing cell phone?

Back

A ringing cell phone produces sound energy.

Front

What type of energy does a microwave oven primarily transform electrical energy into?

Back

A microwave oven primarily transforms electrical energy into thermal energy.

Front

What type of energy is NOT produced by a microwave oven?

Back

Solar energy is not produced by a microwave oven.

Front

What is mechanical energy?

Back

Mechanical energy is the sum of potential and kinetic energy in an object, which is used to do work.

Front

What is sound energy?

Back

Sound energy is a form of energy that is associated with the vibration of particles in a medium, such as air or water.

Front

What is an example of energy conversion from electrical to sound?

Back

An example is a speaker that converts electrical energy into sound energy.

Front

What is thermal energy?

Back

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