Energy Transformations, KE and PE

Front

What is energy transformation?

Back

Energy transformation is the process of changing energy from one form to another.

Front

What type of energy conversion occurs when gasoline is used in a car?

Back

Chemical energy is converted to mechanical energy.

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or state.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion.

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

Where is potential energy highest in a roller coaster?

Back

Potential energy is highest at the highest point of the roller coaster.

Front

Where is kinetic energy highest in a roller coaster?

Back

Kinetic energy is highest at the lowest point of the roller coaster.

Front

What is an example of energy transformation in a light bulb?

Back

In a light bulb, electrical energy is transformed into light and thermal energy.

Front

What is the relationship between potential energy and height?

Back

Potential energy increases with height; the higher an object is, the more potential energy it has.
