Potential and Kinetic Energy

Front

What is the definition of kinetic energy?

Back

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

Front

What is potential energy?

Back

Potential energy is the stored energy of an object due to its position or state, such as height or configuration.

Front

Where is kinetic energy at its minimum?

Back

Kinetic energy is at its minimum when an object is at rest.

Front

What is an example of potential energy?

Back

A rock held at the top of a hill has potential energy due to its height.

Front

What is an example of kinetic energy?

Back

A car moving down the road has kinetic energy due to its motion.

Front

What is the relationship between potential energy and kinetic energy?

Back

Potential energy can be converted into kinetic energy and vice versa, depending on the object's motion and position.

Front

What is the formula for calculating kinetic energy?

Back

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

Front

What is the formula for calculating potential energy?

Back

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

Front

What is an example of an activity that demonstrates kinetic energy?

Back

A person running or a ball rolling down a hill demonstrates kinetic energy.

What is an example of an activity that demonstrates potential energy?

Back

A drawn bowstring or a water reservoir at a height demonstrates potential energy.
