Potential vs. Kinetic Energy

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or height. It is the energy that 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 square of its speed.

Front

How is kinetic energy calculated?

Back

Kinetic energy (KE) is calculated using the formula: KE = 1/2 mv², where m is mass and v is speed.

Front

What happens to kinetic energy when speed doubles?

Back

When speed doubles, the kinetic energy quadruples.

Front

What is the relationship between mass and potential energy?

Back

Mass is directly proportional to potential energy; as mass increases, potential energy increases.

Front

What is the relationship between height and potential energy?

Back

Height is directly proportional to potential energy; as height increases, potential energy increases.

Front

Which object has the most potential energy: a ball at 3 meters, 2 meters, 1 meter, or on the ground?

Back

A ball held at 3 meters has the most potential energy.

Front

Where does a roller coaster cart have the greatest kinetic energy?

Back

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

Front

What type of graph represents the relationship between kinetic energy and speed?

Back

The relationship between kinetic energy and speed is represented by a parabolic graph.

Front

What is the formula for potential energy?

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.
