In which position does an object have maximum potential energy?

Back

An object has maximum potential energy at the highest point in its path.

Front

In which position does an object have maximum kinetic energy?

Back

An object has maximum kinetic energy at the lowest point in its path or when it is moving fastest.

What is the formula for calculating potential energy?

Back

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

How does energy transform between potential and kinetic energy?

Back

Energy transforms from potential to kinetic energy as an object falls, and from kinetic to potential energy as it rises.

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.
