Potential and Kinetic Energy

Front

What is potential energy?

Back

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

Front

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 speed at which it is moving.

Front

What is the formula for kinetic energy?

Back

The formula for kinetic energy (KE) is KE = 1/2 mv², where m is mass and v is velocity.

Front

What factors affect potential energy?

Back

Potential energy is affected by the height of an object above a reference point and the mass of the object.

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the potential energy an object has due to its height above the ground, calculated as PE = mgh, where m is mass, g is acceleration due to gravity, and h is height.

Front

How does energy transform between potential and kinetic?

Back

Energy transforms from potential to kinetic when an object moves from a higher position to a lower position, such as a rock falling from a cliff.

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

Give an example of potential energy in everyday life.

Back

An example of potential energy is a stretched rubber band, which has stored energy that can be released when it is let go.

Front

Give an example of kinetic energy in everyday life.

Back

An example of kinetic energy is a moving car, which has energy due to its motion.

Front

What happens to kinetic energy as speed increases?

Back

As speed increases, kinetic energy increases exponentially because it is proportional to the square of the speed.
