S8P2 Energy

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or state. For example, a rock at the top of a hill has potential energy because of its height.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion. The faster an object moves, the more kinetic energy it has.

Front

What happens to potential energy as an object falls?

Back

As an object falls, its potential energy is converted into kinetic energy.

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 transformation occurs when a fan is turned on?

Back

When a fan is turned on, electrical energy is transformed into mechanical energy.

Front

How does a hot air balloon rise?

Back

A hot air balloon rises by converting chemical energy (from burning fuel) into thermal energy, which heats the air inside the balloon, creating lift.

Front

What is an example of energy transformation in a waterfall?

Back

In a waterfall, potential energy is transformed into kinetic energy as the water falls.

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the energy an object possesses because of its height above the ground and the gravitational force acting on it.

Front

What is an example of kinetic energy?

Back

A moving car is an example of kinetic energy, as it is in motion and has the ability to do work.

Front

What is thermal energy?

Back

Thermal energy is the energy that comes from the temperature of matter. It is the total kinetic energy of particles in a substance.
