What is average speed?

Back

Average speed is the total distance traveled divided by the total time taken. It is measured in meters per second (m/s).

How do you calculate average speed?

Back

Average speed = Total distance / Total time.

What happens to a liquid when thermal energy is removed?

Back

The atoms in the liquid lose kinetic energy, causing it to freeze and change to a solid.

What does the Theory of the Conservation of Energy state?

Back

Energy can never be created nor destroyed; it can only change its form from one type to another.

What is Newton's 1st Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net external force.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object due to its motion, calculated as KE = 1/2 mv², where m is mass and v is velocity.

What is potential energy?

Back

Potential energy is the stored energy of an object due to its position or state, such as gravitational potential energy.

Front

What is the formula for calculating gravitational potential energy?

Back

Gravitational potential energy (PE) = mgh, where m is mass, g is acceleration due to gravity, and h is height.

Front

What is thermal energy?

Back

Thermal energy is the total kinetic energy of particles in a substance, related to its temperature.
