Energy Transformations Review

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 heat energy.

Front

What type of energy is transformed when water is heated in an electric kettle?

Back

Electrical energy is transformed into heat energy.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion.

Front

What is potential energy?

Back

Potential energy is the stored energy of an object due to its position or state.

Front

What is elastic potential energy?

Back

Elastic potential energy is the energy stored in elastic materials as the result of their stretching or compressing.

Front

What happens to energy when gasoline is burned in a car engine?

Back

Chemical energy is converted into mechanical energy.

Front

What is the relationship between kinetic and potential energy in a skateboarder going down a hill?

Back

As the skateboarder descends, potential energy decreases while kinetic energy increases.

Front

What type of energy does a ceiling fan use to operate?

Back

A ceiling fan uses electrical energy to operate.

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 difference between mechanical energy and electrical energy?

Back

Mechanical energy is the sum of potential and kinetic energy in an object, while electrical energy is the energy caused by the movement of electrons.
