The process of transforming primary energy sources into secondary sources like electricity.

A device that converts heat energy into mechanical work, commonly found in vehicles.

The transition of a substance from solid to gas without passing through a liquid state.

A fluid movement caused by uneven heating, such as that between land and sea.

Environmental harm caused by excessive heat discharged from buildings or vehicles.

The three main methods of heat movement: conduction, convection, and radiation.

The transfer of heat through electromagnetic waves without needing a medium.

The most common secondary energy source utilized in homes, primarily electrical energy.

Constructed with gaps to accommodate metal expansion due to heat.

The process where cold water is pushed down, heated at the bottom, and rises in a cycle.

The total distance traveled divided by total time taken.

The displacement divided by the total time taken for the journey.

A force that causes an object to accelerate due to net force not being zero.

Forces acting on an object that are equal in size and opposite in direction, resulting in no movement.

The attraction between two bodies due to their mass and distance; responsible for weight on Earth.

The shortest distance from the initial to the final position with direction included.

A graphic representation of the forces acting on an object using arrows to show their direction and magnitude.

The SI unit of force; amount required to accelerate a 1 kg mass by 1 m/s².

The pulling force transmitted through a string, rope, or cable when it is pulled tight.

A push or pull acting upon an object, measured by magnitude and direction.
