S8P2 Milestone Review

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases). Warm air or liquid rises, while cooler air or liquid sinks, creating a circulation pattern.

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the energy an object possesses due to its position in a gravitational field. The higher the object is positioned, the greater its potential energy.

Front

What is energy transformation?

Back

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

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials. It occurs when heat moves from a hotter object to a cooler one.

Front

What is radiation?

Back

Radiation is the transfer of energy through electromagnetic waves. It does not require a medium and can occur in a vacuum.

Front

What happens to warm air?

Back

Warm air rises because it is less dense than cooler air, which causes it to move upward.

Front

What happens to cool air?

Back

Cool air sinks because it is denser than warm air, leading to a downward movement.

Front

What is the relationship between height and gravitational potential energy?

Back

The gravitational potential energy of an object increases as its height above the ground increases.

Front

What is an example of energy transformation?

Back

An example of energy transformation is a battery converting chemical energy into electrical energy to power a device.

Front

What is the maximum potential energy of an object?

Back

The maximum potential energy of an object occurs at its highest point in a gravitational field.
