Conservation of Energy

Front

What is the definition of Kinetic Energy?

Back

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

Front

What is the definition of Potential Energy?

Back

Potential Energy is the stored energy of an object due to its position or state, commonly gravitational potential energy, calculated as PE = mgh, where m is mass, g is acceleration due to gravity, and h is height.

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 Kinetic Energy?

Back

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

Front

How do you calculate Potential Energy?

Back

Potential Energy (PE) is calculated using the formula PE = mgh, where m is the mass, g is the acceleration due to gravity, and h is the height above a reference point.

What happens to energy at the highest point of a roller coaster?

Back

At the highest point of a roller coaster, gravitational potential energy is at its maximum, while kinetic energy is at its minimum.

Front

What happens to energy at the lowest point of a roller coaster?

Back

At the lowest point of a roller coaster, kinetic energy is at its maximum, while gravitational potential energy is at its minimum.

Front

What is an example of Kinetic Energy in everyday life?

Back

An example of Kinetic Energy is a moving car, where the energy is due to its motion.

Front

What is an example of Potential Energy in everyday life?

Back

An example of Potential Energy is a book on a shelf, where the energy is stored due to its height above the ground.

Front

What is the relationship between Kinetic and Potential Energy in a closed system?

Back

In a closed system, the total energy remains constant; as potential energy decreases, kinetic energy increases, and vice versa.
