Level 1: Conservation of 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 ball held at a height has potential energy because of its position above the ground.

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 decreases while its kinetic energy increases, demonstrating the conservation of 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 is harnessed from the sun?

Back

The sun provides light and thermal energy that can be harnessed for solar power.

Front

How is work related to energy?

Back

Work transfers energy from one object to another. When work is done on an object, energy is transferred to that object.

Front

What type of energy do we get from food?

Back

We get chemical energy from the food we eat, which our bodies convert into usable energy.

Front

What happens to energy in a roller coaster as it goes downhill?

Back

As a roller coaster goes downhill, potential energy is converted into kinetic energy.

Front

What is an example of energy transformation?

Back

An example of energy transformation is a light bulb converting electrical energy into light and thermal energy.

Front

What is solar energy?

Back

Solar energy is the energy obtained from the sun's rays, which can be converted into thermal or electrical energy.
