Potential Energy, Kinetic Energy, Mass, and Speed

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or configuration, which can be converted into kinetic energy.

Front

How can you increase the potential energy of an object?

Back

You can increase the potential energy of an object by raising it to a higher position.

Front

What type of energy is stored when a rubber band is stretched?

Back

The energy stored when a rubber band is stretched is called potential energy.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion, which depends on its mass and 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 is the relationship between mass and kinetic energy?

Back

Kinetic energy is directly proportional to the mass of the object; as mass increases, kinetic energy increases if speed remains constant.

Front

What is the relationship between speed and kinetic energy?

Back

Kinetic energy is proportional to the square of the speed; if speed doubles, kinetic energy increases by a factor of four.

Front

Which of the following is NOT an example of potential energy?

Back

Electricity is not an example of potential energy.

Front

What is the definition of energy?

Back

Energy is the ability to do work or cause change.

Front

What happens to potential energy as an object falls?

Back

As an object falls, its potential energy decreases while its kinetic energy increases.
