Understanding Heat Energy

Front

What is heat energy?

Back

Heat energy is a form of energy that is transferred between objects due to a temperature difference. It makes things warmer.

Front

What happens when two objects rub against each other?

Back

When two objects rub against each other, they create friction, which can produce heat energy.

Front

What is friction?

Back

Friction is the resistance that one surface or object encounters when moving over another. It can generate heat.

Front

How does adding wheels to a board affect friction?

Back

Adding wheels reduces friction, allowing the board to slide more easily and faster.

Front

What happens to the temperature of an object when it produces more friction?

Back

The temperature of the object increases because more heat energy is produced.

Front

What is the effect of sunlight on temperature?

Back

Sunlight increases the temperature of objects exposed to it, as they absorb heat energy.

Front

What is a thermometer used for?

Back

A thermometer is used to measure the temperature of an object or environment.

Front

What does it mean if a thermometer shows a higher temperature?

Back

A higher temperature indicates that the object is warmer and has more heat energy.

Front

What can happen to metal tracks when a train passes over them?

Back

The metal tracks can become warmer due to the heat generated by the train's movement.

Front

What is the relationship between temperature and heat energy?

Back

Temperature is a measure of the average kinetic energy of particles in a substance, while heat energy is the energy transferred due to temperature differences.
