T3L2 KE & PE

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or state. It has the potential to do work when released.

Front

At what point does a thrown ball have the most potential energy?

Back

At the highest point of its trajectory.

Front

What factors affect gravitational potential energy?

Back

Gravitational potential energy is affected by the height of the object above the ground and its mass.

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

Which object has elastic potential energy?

Back

A stretched bow.

Front

What is the formula for gravitational potential energy?

Back

Gravitational potential energy (GPE) = mass (m) × gravitational acceleration (g) × height (h).

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion, depending on its mass and speed.

Front

What is the relationship between mass and kinetic energy?

Back

Kinetic energy increases with the mass of the object and the square of its speed.

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 the difference between kinetic energy and potential energy?

Back

Kinetic energy is the energy of motion, while potential energy is stored energy based on position.
