Potential and Kinetic Energy Review

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.

Where is potential energy the greatest in a roller coaster?

Back

Potential energy is greatest at the highest points of the roller coaster.

Front

Where is kinetic energy the greatest in a roller coaster?

Back

Kinetic energy is greatest at the lowest points of the roller coaster, where the speed is highest.

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 relationship between potential and kinetic energy?

Back

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

Front

At which point on a ramp does a soap box derby car have maximum potential energy?

Back

At the top of the ramp.

Front

At which point on a ramp does a soap box derby car have maximum kinetic energy?

Back

At the bottom of the ramp.

Front

What is the formula for kinetic energy?

Back

Kinetic energy (KE) = 1/2 mv², where m is mass and v is velocity.

Front

What is the formula for potential energy?

Back

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