What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or configuration. It is often associated with the height of an object above the ground.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion. It depends on the mass of the object and the speed at which it is moving.

Front

How does height affect potential energy?

Back

The higher an object is positioned, the greater its potential energy. This is because potential energy is directly proportional to height.

Front

What happens to potential energy as an object falls?

Back

As an object falls, its potential energy decreases while its kinetic energy increases.

Front

What is the formula for calculating potential energy?

Back

Potential Energy (PE) = mass (m) × gravitational acceleration (g) × height (h).

Front

What is the relationship between mass and potential energy?

Back

Potential energy increases with mass. A heavier object at the same height has more potential energy than a lighter object.

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the potential energy an object possesses due to its position in a gravitational field, typically related to its height above the ground.

Front

What is the significance of the highest point in a fall?

Back

At the highest point, an object has maximum potential energy and minimum kinetic energy.

Front

What is the significance of the lowest point in a fall?

Back

At the lowest point, an object has minimum potential energy and maximum kinetic energy.

Front

How does mass affect kinetic energy?

Back

Kinetic energy increases with mass. A heavier object moving at the same speed has more kinetic energy than a lighter object.
