What is gravitational potential energy?

Back

Gravitational potential energy is the energy an object possesses due to its position in a gravitational field, typically measured relative to a reference point.

What is the law of conservation of energy?

Back

The law of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another.

What is absolute zero?

Back

Absolute zero is the theoretical temperature at which a system has minimal thermal energy, defined as 0 Kelvin or -273.15 degrees Celsius.

What is a thermal insulator?

Back

A thermal insulator is a material that resists the transfer of heat, preventing heat flow between objects.

What is kinetic energy?

Back

Kinetic energy is the energy of an object due to its motion, calculated as 1/2 mv², where m is mass and v is velocity.

Front

What is the relationship between temperature and kinetic energy?

Back

Temperature is a measure of the average kinetic energy of the particles in a substance; as temperature increases, the kinetic energy of the particles also increases.

What is thermal equilibrium?

Back

Thermal equilibrium is the state in which two objects in contact with each other reach the same temperature, resulting in no net heat transfer between them.

What is conduction?

Back

Conduction is the process of heat transfer through direct contact between materials, where heat moves from the hotter object to the cooler one.
