Potential vs. Kinetic Energy

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or configuration, often related to its height above the ground.

What is kinetic energy?

Back

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

How is potential energy calculated for an object at height?

Back

Potential energy (PE) is calculated using the formula PE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.

Front

What happens to potential energy as an object falls?

Back

As an object falls, its potential energy decreases while its kinetic energy increases, conserving the total mechanical energy.

What is the relationship between speed and kinetic energy?

Back

Kinetic energy is proportional to the square of the speed; if the speed doubles, the kinetic energy increases by a factor of four.

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.

What is an example of potential energy being converted to kinetic energy?

Back

An example is a roller coaster cart descending from a height; as it falls, its potential energy converts to kinetic energy.

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

At what point does a roller coaster cart have maximum kinetic energy?

Back

A roller coaster cart has maximum kinetic energy at the bottom of the highest hill.

Can kinetic energy be converted to potential energy?

Back

Yes, kinetic energy can be converted to potential energy, such as when an object is lifted against gravity.
