What is thermal energy?

Back

Thermal energy is the total kinetic energy of the particles in an object, which depends on its temperature and mass.

Front

What factors affect the total thermal energy in an object?

Back

The total thermal energy in an object depends on its temperature, mass, and specific heat.

Front

What is radiation in terms of energy transfer?

Back

Radiation is the transfer of energy through electromagnetic waves, allowing thermal energy to be transferred without the need for a medium.

Front

How does gravity affect a planet's orbit around the Sun?

Back

Gravity from the Sun pulls the planet towards it, causing the planet to speed up when it is closer to the Sun and slow down when it is farther away.

Front

What happens to an object in space without the influence of gravity?

Back

Without the influence of gravity, an object in space would move in a straight line at a constant speed.

Front

What is specific heat?

Back

Specific heat is the amount of heat required to raise the temperature of one gram of a substance by one degree Celsius.

Front

What is the difference between conduction, convection, and radiation?

Back

Conduction is heat transfer through direct contact, convection is heat transfer through fluid movement, and radiation is heat transfer through electromagnetic waves.

Front

What is an example of energy transfer by conduction?

Back

An example of conduction is when a metal spoon becomes warm after being placed in a hot soup.

Front

What is an example of energy transfer by convection?

Back

An example of convection is warm air rising above a heater, creating a circulation of warm air in the room.

Front

What is the role of the Sun in the Earth's climate?

Back

The Sun provides thermal energy that drives weather patterns and supports life on Earth.
