Energy Review

Front

What is kinetic energy?

Back

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

Front

When is kinetic energy at its maximum on a roller coaster?

Back

Kinetic energy is at its maximum at the bottom of each hill.

Front

What is electrical energy?

Back

Electrical energy is the energy caused by the movement of electrons. It can be converted into other forms of energy.

Front

How is electrical energy transferred to thermal energy?

Back

Electrical energy can be converted to thermal energy through resistance in wires or appliances, causing them to heat up.

Front

What is solar energy?

Back

Solar energy is the energy from the sun that can be converted into other forms of energy, such as electrical energy.

Front

How is solar energy converted to electrical energy?

Back

Solar energy is converted to electrical energy using solar panels, which capture sunlight and convert it into electricity.

Front

What is a longitudinal wave?

Back

A longitudinal wave is a type of wave where the particles of the medium move parallel to the direction of the wave's travel.

Front

What is a transverse wave?

Back

A transverse wave is a type of wave where the particles of the medium move perpendicular to the direction of the wave's travel.

Front

What is the relationship between energy and motion?

Back

Energy is required to create motion; as an object moves, it possesses kinetic energy.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state. For example, a roller coaster at the top of a hill has potential energy.
