What is kinetic energy?

Back

Kinetic energy is the energy that 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 stored energy of an object due to its position or state, commonly associated with gravitational and elastic potential energy.

Front

At which point in a pendulum's swing is kinetic energy at its maximum?

Back

Kinetic energy is at its maximum at the lowest point of the swing.

Front

At which points in a pendulum's swing is potential energy at its maximum?

Back

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

Front

What is elastic potential energy?

Back

Elastic potential energy is the energy stored in elastic materials as the result of their stretching or compressing.

Front

What happens to kinetic energy as a pendulum swings upward?

Back

As a pendulum swings upward, kinetic energy is converted into potential energy.

Front

What happens to potential energy as a pendulum swings downward?

Back

As a pendulum swings downward, potential energy is converted into kinetic energy.

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 friction affect energy in a pendulum system?

Back

Friction dissipates energy as heat, reducing the total mechanical energy of the pendulum system over time.

Front

What is the formula for gravitational potential energy?

Back

Gravitational potential energy is calculated as PE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.
