Front

What is energy?

Back

Energy is the ability to do work or cause change. It exists in various forms, including kinetic, potential, thermal, chemical, and electrical.

Front

What are fossil fuels?

Back

Fossil fuels are natural substances formed from the remains of ancient plants and animals, primarily consisting of coal, oil, and natural gas.

Front

Which of the following is NOT a fossil fuel?

Back

Water is not a fossil fuel.

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the energy an object possesses due to its position in a gravitational field, typically related to its height.

Front

How can you increase gravitational potential energy?

Back

You can increase gravitational potential energy by raising the height of an object in a gravitational field.

Front

What is conduction?

Back

Conduction is the transfer of heat through a material without the movement of the material itself, typically occurring in solids.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases) caused by differences in temperature and density.

Front

What is radiation?

Back

Radiation is the transfer of energy through electromagnetic waves, such as light or heat, without the need for a medium.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion, depending on its mass and velocity.

Front

What is potential energy?

Back

Potential energy is the stored energy of an object due to its position or state, such as height or configuration.
