What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or configuration. It is the energy that has the potential to be converted into kinetic energy.

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion. It depends on the mass of the object and the square of its velocity.

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.

What is a longitudinal wave?

Back

A longitudinal wave is a type of wave in which the particles of the medium move parallel to the direction of the wave's propagation.

What is the relationship between potential energy and height?

Back

Potential energy increases with height; the higher an object is positioned, the more potential energy it has due to gravitational force.

Front

What factors affect kinetic energy?

Back

Kinetic energy is affected by the mass of the object and its velocity. The formula for kinetic energy is KE = 1/2 mv².

How does energy transformation occur in a pendulum?

Back

In a pendulum, energy transforms between potential energy at the highest points and kinetic energy at the lowest point.

What is the formula for calculating potential energy?

Back

The formula for potential energy is PE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.
