What are the main energy stores?

Thermal (internal) Kinetic Gravitational potential Elastic potential Chemical Magnetic Electrostatic Nuclear

How is energy transferred between stores?

Heating Mechanical work Electrical work Radiation (light, infrared, etc.)

What is power?

Power is the rate at which energy is transferred.

What is specific heat capacity?

Specific heat capacity is the energy needed to raise the temperature of 1 kg of a substance by 1°C (or 1 K). Unit: J/kg°C

Describe the specific heat capacity practical.

Measure the mass of a block. Insert a heater and thermometer. Record the starting temperature. Turn on the heater for a known time. Measure the temperature increase. Calculate energy change

define renewable

infinite

What are renewable source

Solar Wind Hydroelectric Tidal Wave Geothermal Biofuel

define non-renewable

finite

What are non-renewable energy resources?

Coal Oil Natural gas Nuclear fuel

Describe the insulation practical.

Fill containers with hot water. Add different insulating materials. Measure the starting temperature. Leave for a fixed time. Measure the final temperature. Compare temperature decreases.

Why is insulation important in homes?

Insulation reduces energy transfer by heating.

whats the equation for kinetic energy

Ek = 0.5 x m x v (squared)
