Energy Transformation

Front

What is energy transformation?

Back

Energy transformation is the process of changing energy from one form to another, such as from chemical energy to mechanical energy.

What type of energy transformation occurs when a hawk eats a mouse?

Back

The energy transformation is from chemical energy (in the mouse) to mechanical energy (used by the hawk to fly).

Where is kinetic energy the greatest in a system?

Back

Kinetic energy is greatest at the point of maximum speed or movement, often at the lowest point in a gravitational field.

Front

What energy transformation occurs when a car burns gasoline?

Back

The energy transformation is from chemical energy (in gasoline) to thermal energy (from combustion) to mechanical energy (movement of the car).

Front

What is an example of energy transformation from electrical to mechanical?

Back

An electric motor is an example of energy transformation from electrical energy to mechanical energy.

Front

What does a hairdryer convert?

Back

A hairdryer converts electrical energy into thermal energy.

Front

What is chemical energy?

Back

Chemical energy is the energy stored in the bonds of chemical compounds, like atoms and molecules.

Front

What is mechanical energy?

Back

Mechanical energy is the sum of potential energy and kinetic energy in an object that is used to do work.

Front

What is thermal energy?

Back

Thermal energy is the internal energy present in a system due to its temperature, which is a measure of the average kinetic energy of its particles.

Front

How does energy transformation relate to 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.
