Energy Transformations

Front

What is the Law of Conservation of Energy?

Back

The Law of Conservation of Energy states that energy cannot be created or destroyed, only transformed from one form to another.

Front

What are energy transformations?

Back

Energy transformations are changes from one form of energy to another, such as from chemical energy to electrical energy.

Front

What type of energy transformation occurs in a battery-operated device?

Back

In a battery-operated device, the energy transformation typically goes from chemical energy to electrical energy to sound energy.

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the energy an object possesses due to its height and mass.

Front

What factors affect gravitational potential energy?

Back

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

Front

When does an object have potential energy?

Back

An object has potential energy when it is at rest or not in motion, such as a swing at its highest point.

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 velocity.

Front

What is an example of energy transformation in nature?

Back

An example of energy transformation in nature is photosynthesis, where plants convert solar energy into chemical energy.

What happens to energy during a roller coaster ride?

Back

During a roller coaster ride, potential energy is converted to kinetic energy as the coaster descends.
