Conservation of Energy

What is the definition of Gravitational Potential Energy (GPE)?

Back

Gravitational Potential Energy (GPE) is the energy an object possesses due to its position in a gravitational field, calculated as GPE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.

Front

What is the definition of Kinetic Energy (KE)?

Back

Kinetic Energy (KE) is the energy an object has due to its motion, calculated as KE = 1/2 mv², where m is mass and v is velocity.

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

How do you calculate Total Mechanical Energy?

Back

Total Mechanical Energy is the sum of Gravitational Potential Energy (GPE) and Kinetic Energy (KE): Total Energy = GPE + KE.

Front

What happens to GPE as an object falls?

Back

As an object falls, its Gravitational Potential Energy (GPE) decreases while its Kinetic Energy (KE) increases, keeping the total mechanical energy constant.

Front

What is the relationship between GPE and height?

Back

Gravitational Potential Energy (GPE) is directly proportional to height; as height increases, GPE increases.

Front

What is the relationship between KE and speed?

Back

Kinetic Energy (KE) is proportional to the square of the speed; if speed doubles, KE increases by a factor of four.

Front

What is an example of energy transformation?

Back

An example of energy transformation is a roller coaster: as it climbs, kinetic energy is converted to gravitational potential energy, and as it descends, GPE is converted back to KE.

Front

What is the formula for calculating GPE?

Back

The formula for calculating Gravitational Potential Energy (GPE) is GPE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.

Front

What is the formula for calculating KE?

Back

The formula for calculating Kinetic Energy (KE) is KE = 1/2 mv², where m is mass and v is velocity.
