What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials. For example, walking on hot sand transfers heat from the sand to your feet.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases). An example is boiling water, where hot water rises and cooler water sinks, creating a circular motion.

Front

What is radiation?

Back

Radiation is the transfer of energy through electromagnetic waves. An example is feeling the warmth of the sun on your skin.

Front

What is energy?

Back

Energy is the ability to do work or cause change. It exists in various forms, such as kinetic and potential energy.

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the energy an object possesses due to its position in a gravitational field. The higher the object, the more gravitational potential energy it has.

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 energy when you throw a ball into the air?

Back

As the ball rises, kinetic energy is converted into gravitational potential energy. At its highest point, the ball has the most gravitational potential energy.

Front

What is the relationship between kinetic and potential energy?

Back

Kinetic energy and potential energy can convert into each other. For example, when a ball is thrown up, kinetic energy decreases while potential energy increases.

Front

What is an example of energy transformation?

Back

An example of energy transformation is a roller coaster. As it climbs, kinetic energy is transformed into potential energy, and as it descends, potential energy is transformed back into kinetic energy.

Front

What is thermal energy?

Back

Thermal energy is the total energy of all the particles in an object, related to its temperature. It increases when heat is added.
