Grade 8 S1 Final Review

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or state. It has the potential to be converted into kinetic energy.

Front

What happens to energy when it changes types?

Back

Energy converts from one form to another, such as kinetic energy converting to potential energy or light energy.

Front

What is energy transfer?

Back

Energy transfer is the process of energy moving from one object to another.

Front

Is the statement 'The motor is transferring electrical energy to kinetic energy' true or false?

Back

False. The motor converts electrical energy into kinetic energy.

Front

Do only living things have energy?

Back

False. Energy exists in both living and non-living things.

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 the formula for kinetic energy?

Back

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

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 is an example of energy conversion?

Back

An example of energy conversion is a roller coaster, where potential energy at the top converts to kinetic energy as it descends.

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the potential energy held by an object because of its height above the ground.
