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 book on a shelf has potential energy because of its height.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion. For example, a moving skateboard has kinetic energy.

Front

What is the unit of measurement for energy?

Back

The unit of measurement for energy is Joule.

Front

At which point in a pendulum's swing is kinetic energy highest?

Back

Kinetic energy is highest at the lowest point of the swing.

Front

What factors affect potential energy?

Back

Potential energy depends on the height of an object and its mass.

Front

What factors affect kinetic energy?

Back

Kinetic energy depends on the mass of the object and the square of its velocity.

Front

How is potential energy converted to kinetic energy?

Back

Potential energy is converted to kinetic energy when an object falls or moves from a higher position to a lower position.

Front

What is the relationship between potential and kinetic energy in a roller coaster?

Back

In a roller coaster, potential energy is highest at the top of the hills, and kinetic energy is highest at the lowest points.

Front

Can an object have both potential and kinetic energy at the same time?

Back

Yes, an object can have both potential and kinetic energy at the same time, such as a swinging pendulum.

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the potential energy an object has due to its height above the ground.
