Work, KE, GPE, and Heat Review

Front

What is Kinetic Energy?

Back

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

Front

What is Gravitational Potential Energy?

Back

Gravitational Potential Energy is the energy stored in an object due to its height above the ground, calculated as GPE = mgh, where m is mass, g is acceleration due to gravity, and h is height.

Front

What is Mechanical Energy?

Back

Mechanical Energy is the sum of potential energy and kinetic energy in a system.

Front

What is Work in physics?

Back

Work is done when a force causes an object to move, calculated as Work = Force x Distance.

Front

What is the formula for calculating Work?

Back

Work = Force x Distance (W = F x d) where W is work, F is force, and d is distance.

Front

What is Thermal Energy?

Back

Thermal Energy is the energy that comes from the temperature of matter, often associated with heat transfer.

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

At which point of a roller coaster is the potential energy greatest?

Back

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

Front

At which point of a roller coaster is the kinetic energy greatest?

Back

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

Front

What is the relationship between potential energy and height?

Back

Potential energy increases with height; the higher an object is, the more potential energy it has.
