What is an Energy system?

In an Energy System, energy is TRANSFORMED from one form into another.

What three things make up an energy system?

1. INPUT 2. PROCESS 3. OUTPUT

What is POTENTIAL ENERGY?

POTENTIAL ENERGY is energy stored in an object.

What is KINETIC ENERGY?

Kinetic energy is the ENERGY OF MOTION.

What is Energy measured in?

Energy is measured in joules (J).

Give examples of Energy Systems?

1. Mechanical systems 2. Thermal systems 3. Electrical systems 4. Biological systems

Do moving object have Potential or Kinetic Energy?

kinetic energy

Give 3 forms of kinetic energy

1. Vibrational 2. Rotational 3. Translational

The amount of kinetic energy an object has depends on what 2 things?

The mass (m) of the object and the speed (v) of the object.

What is GRAVITATIONAL potential energy?

Gravitational potential energy is energy an object possesses because of its position in a gravitational field.

What is ELECTRICAL ENERGY?

Particles traveling through a wire to create an electric current is electrical energy.

What is THERMAL ENERGY?

The energy that comes from the temperature of the heated substance.

What happens in a THERMAL ENERGY SYSTEM?

Thermal energy is transferred from one object to another.

What is HEAT measured in?

Heat is measured in joules (J). This is because heat is a transfer of energy.

In which 3 ways does HEAT ENERGY TRANSFER happen?

Heat (energy transfer) occurs in three ways: 1. CONDUCTION 2. CONVECTION 3. RADIATION

What happens in CONDUCTION in HEAT?

During conduction, the objects must be touching each other for energy transfer to take place.
