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. 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 its velocity.

Front

How is potential energy converted to kinetic energy on a roller coaster?

Back

As a roller coaster climbs to the top of a hill, it gains potential energy. When it descends, that potential energy is converted into kinetic energy.

Front

Where is potential energy highest on a roller coaster?

Back

Potential energy is highest at the top of a big hill.

Front

What happens to kinetic energy as an object speeds up?

Back

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

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

If a 12 kg skateboard is rolling at 5 m/s, how much kinetic energy does it have?

Back

150 J (Joules) of kinetic energy.

Front

What type of energy is associated with an object at rest?

Back

Potential energy is associated with an object at rest due to its position.

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 gravitational force.

Front

Can potential energy be converted into other forms of energy?

Back

Yes, potential energy can be converted into kinetic energy, thermal energy, and other forms of energy.
