Energy Transformation and Heat Transfer

Front

What is energy transformation?

Back

Energy transformation is the process of changing energy from one form to another, such as converting potential energy into kinetic energy.

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object possesses due to its motion. It depends on the mass and speed of the object.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state. For example, a ball held at a height has gravitational potential energy.

Front

What does the law of conservation of energy state?

Back

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

Front

How does speed affect kinetic energy?

Back

The faster an object moves, the more kinetic energy it has.

Front

What is heat transfer?

Back

Heat transfer is the movement of thermal energy from one object or substance to another, occurring through conduction, convection, or radiation.

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials, where faster-moving particles transfer energy to slower-moving particles.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases) caused by differences in temperature and density.

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves, such as infrared radiation from a heat source.

Front

What happens to potential energy when an object falls?

Back

As an object falls, its potential energy decreases while its kinetic energy increases, demonstrating energy transformation.
