Front

What is gravitational force?

Back

Gravitational force is the attraction between two masses, which keeps celestial bodies in orbit.

Front

Define conduction in the context of heat transfer.

Back

Conduction is the transfer of heat through direct contact between materials.

Front

What is thermal equilibrium?

Back

Thermal equilibrium is the state in which two bodies reach the same temperature and no heat flows between them.

Front

What is an elliptical orbit?

Back

An elliptical orbit is an oval-shaped path that a celestial body follows around another body due to gravitational forces.

Front

What is the role of gravity in the motion of planets?

Back

Gravity keeps planets in orbit around the Sun and governs their motion in space.
