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 it can fall.

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

Where is potential energy at its minimum?

Back

Potential energy is at its minimum at point X.

Front

Where is kinetic energy at its maximum?

Back

Kinetic energy is at its maximum at point X.

Front

How do you calculate kinetic energy?

Back

Kinetic energy (KE) can be calculated using the formula: KE = 1/2 * mass * velocity^2.

Front

What is the kinetic energy of a cheetah with a mass of 47 kg running at 31 m/s?

Back

The kinetic energy is 22,583.5 J.

Front

Which point has the most potential energy?

Back

Point A has the most potential 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 relationship between potential and kinetic energy?

Back

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

Front

What is an example of potential energy?

Back

A stretched rubber band has potential energy because it can snap back to its original shape.
