Exam Review: Energy

Front

What does gravitational potential energy depend on?

Back

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

Front

What is the formula for calculating kinetic energy?

Back

Front

How effective is convection in heating a room compared to conduction?

Back

Convection is more effective because it circulates warm air throughout the room.

Front

How is energy conserved when a pendulum swings from its highest point to its lowest point?

Back

The potential energy is converted to kinetic energy at the lowest point.

Front

What is conduction in heat transfer?

Back

Conduction is the transfer of heat through direct contact between materials.

Front

Define kinetic energy.

Back

Kinetic energy is the energy an object possesses due to its motion.

Front

What is the formula for gravitational potential energy?

Back

Front

Explain the difference between conduction and convection.

Back

Conduction transfers heat through direct contact, while convection transfers heat through the movement of fluids.

Front

What is the principle of conservation of energy?

Back

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

Front

What factors affect the rate of heat transfer by conduction?

Back

The rate of heat transfer by conduction is affected by the material's thermal conductivity, temperature difference, and surface area.
