Potential & Kinetic Energy Review Day 2

Front

What is kinetic energy?

Back

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

Front

What is potential energy?

Back

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

Front

What does the law of conservation of energy state?

Back

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

Front

At which point in a pendulum's swing is kinetic energy highest?

Back

Kinetic energy is highest at the lowest point of the swing.

Front

At which point in a pendulum's swing is potential energy highest?

Back

Potential energy is highest at the highest points of the swing.

Front

What happens to kinetic energy as an object rises?

Back

As an object rises, its kinetic energy decreases while its potential energy increases.

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

In the context of a diver jumping off a diving board, where is kinetic energy greatest?

Back

Kinetic energy is greatest just before the diver enters the water.

Front

In the context of a diver jumping off a diving board, where is potential energy greatest?

Back

Potential energy is greatest at the top of the diving board.

Front

What is the relationship between kinetic and potential energy in a closed system?

Back

In a closed system, the total mechanical energy (kinetic + potential) remains constant, demonstrating the conservation of energy.
