Topic 4 End: Law of Conservation of Energy

Front

What is the Law of Conservation of Energy?

Back

The Law of Conservation of Energy states that energy cannot be created or destroyed, only transformed from one form to another.

Front

What is a Transverse Wave?

Back

A Transverse Wave is a type of wave where the disturbance moves perpendicular to the direction of energy flow.

Front

What is a Longitudinal Wave?

Back

A Longitudinal Wave is a type of wave where the disturbance moves parallel to the direction of energy flow.

Front

What is a Medium in the context of waves?

Back

A Medium is a material that moves energy from one substance to another.

Front

What is Kinetic Energy?

Back

Kinetic Energy is the energy an object possesses due to its motion, determined by its mass and speed.

Front

What is Gravitational Potential Energy?

Back

Gravitational Potential Energy is the energy an object possesses due to its position in a gravitational field, determined by its height and mass.

Front

What is an example of energy transformation?

Back

A battery causing a flashlight to shine is an example of energy transformation from chemical to electrical to light energy.

Front

What is Elastic Potential Energy?

Back

Elastic Potential Energy is the energy stored in elastic materials as the result of their stretching or compressing.

Front

How does energy transformation occur in a bow and arrow?

Back

When the bow is drawn, elastic potential energy is stored; when released, it transforms into kinetic energy of the arrow.

Front

What is the relationship between mass and energy?

Back

Mass is a factor in both kinetic energy (mass and speed) and gravitational potential energy (mass and height).
