Mechanical energy Conservation of Energy

Front

What is mechanical energy?

Back

Mechanical energy is the sum of potential energy and kinetic energy in an object, representing the energy associated with its motion and position.

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 type of energy is transferred through electromagnetic waves?

Back

Radiant energy is the energy transferred through electromagnetic waves such as visible light, ultraviolet light, or X-rays.

Front

When does an object have the greatest potential energy?

Back

An object has the greatest potential energy when it is at its highest point relative to the ground.

Front

What factors affect potential energy?

Back

Potential energy is affected by the height of an object above the ground and its mass.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object due to its motion, calculated as 1/2 mv², where m is mass and v is velocity.

Front

At which point in a swing is kinetic energy highest?

Back

Kinetic energy is highest at the lowest point of the swing.

Front

What happens to energy during a roller coaster ride?

Back

Energy is transformed between potential and kinetic energy, but the total energy remains constant.

Front

What is the relationship between height and potential energy?

Back

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

Front

What is an example of energy transformation?

Back

When a roller coaster climbs a hill, kinetic energy is transformed into potential energy.
