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 the speed at which it is moving.

Front

What factors affect gravitational potential energy?

Back

Gravitational potential energy depends on the height of the object above the ground and its mass.

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 velocity.

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 an example of energy transformation from potential to kinetic energy?

Back

A swing moving back and forth transforms potential energy at its highest point to kinetic energy as it swings down.

Front

At which point is potential energy greatest on a swing?

Back

Potential energy is greatest at the highest points of the swing.

Front

What is the relationship between speed and kinetic energy?

Back

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

Front

Can an object have kinetic energy if it is not moving?

Back

No, an object must be in motion to have kinetic energy.

Front

What is the unit of energy?

Back

The unit of energy is the Joule (J).
