Energy Transformations Flashcard

Front

What is energy transformation?

Back

Energy transformation is the process of changing energy from one form to another, such as converting electrical energy into light energy.

What type of energy does a light bulb convert electrical energy into?

Back

A light bulb converts electrical energy into light and heat energy.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state, such as a roller coaster at the top of a hill.

Front

What type of energy transformation occurs when gasoline is burned in a car engine?

Back

Chemical energy is converted into mechanical energy.

Front

What energy transformation occurs when a plant uses sunlight?

Back

Light energy is transformed into chemical energy during photosynthesis.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion, such as a moving car or a rolling ball.

Front

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

Back

As a roller coaster moves up, potential energy increases; as it moves down, potential energy decreases and kinetic energy increases.

Front

What is sound energy?

Back

Sound energy is a form of energy produced by vibrating objects, which creates sound waves.

Front

What is the formula for calculating kinetic energy?

Back

Kinetic energy (KE) = 1/2 mv², where m is mass and v is velocity.

Front

What is thermal energy?

Back

Thermal energy is the total energy of all the particles in an object, often felt as heat.
