Potential and Kinetic Energy

Front

What is the definition of potential energy?

Back

Potential energy is the energy stored in an object due to its position or configuration.

Front

What is the definition of kinetic energy?

Back

Kinetic energy is the energy of an object due to its motion.

Front

How is potential energy calculated for an object at height?

Back

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.

Front

How is kinetic energy calculated?

Back

Kinetic energy (KE) is calculated using the formula KE = 1/2 mv², where m is mass and v is velocity.

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

At what point on a roller coaster is potential energy greatest?

Back

Potential energy is greatest at the highest point of the roller coaster.

Front

At what point on a roller coaster is kinetic energy greatest?

Back

Kinetic energy is greatest at the lowest point of the roller coaster.

Front

What is the relationship between kinetic energy and speed?

Back

Kinetic energy increases with the square of the speed; if speed doubles, kinetic energy increases by a factor of four.

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.

Front

How does mass affect potential energy?

Back

Potential energy is directly proportional to mass; as mass increases, potential energy increases.
