What is the relationship between potential energy and height?

Back

Potential energy increases with height because it is directly proportional to the height of the object above a reference point.

Front

What is the formula for calculating gravitational potential energy?

Back

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

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 principle of conservation of energy?

Back

The principle of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another.

How does mass affect kinetic energy?

Back

Kinetic energy increases with mass; it is calculated using the formula KE = 1/2 mv², where m is mass and v is velocity.
