What is convection?

Back

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

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or state. It is greatest when an object is at a high position.

Front

What are insulators?

Back

Insulators are materials that do not conduct heat or electricity well. Examples include Styrofoam, wood, and rubber.

Front

What factors affect gravitational potential energy?

Back

Gravitational potential energy depends on the height and mass of an object.

Front

What is the unit of temperature commonly used in science?

Back

The Celsius (°C) and Fahrenheit (°F) scales are commonly used to measure temperature.

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, so it can occur in a vacuum.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion. It depends on the mass and speed of the object.

Front

What is the formula for gravitational potential energy?

Back

The formula for gravitational potential energy is PE = mgh, where PE is potential energy, m is mass, g is the acceleration due to gravity, and h is height.

Front

What is thermal energy?

Back

Thermal energy is the total energy of all the particles in an object, related to its temperature.
