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. For example, a rock at the top of a hill has potential energy because of its height.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion. The faster an object moves, the more kinetic energy it has.

Front

Which object has kinetic energy?

Back

A ball thrown across the yard has kinetic energy because it is in motion.

Front

What factors affect kinetic energy?

Back

Kinetic energy depends on two factors: speed and mass.

Front

How does speed affect kinetic energy?

Back

The faster an object moves, the more kinetic energy it has.

Front

What is the relationship between height and potential energy?

Back

The higher an object is positioned, the more potential energy it has due to gravity.

Front

Can potential energy be converted to kinetic energy?

Back

Yes, potential energy can be converted to kinetic energy. For example, when a rock rolls down a hill, its potential energy converts to kinetic energy.

Front

What happens to potential energy as an object falls?

Back

As an object falls, its potential energy decreases while its kinetic energy increases.

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 is the formula for 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.
