Theme 1: On the Move (Equations of Linear Motion (v = u + at (No distance)…

- - - - Resistance = 0N, Weight = 500N
      - R = 100N, W = 500N
      - R = 500N, W = 500N (Terminal Velocity)
- - - - Average speed = s/t
      - Affected by driver alertness
    - - Equations of Motion
      - Affected by road and car conditions
- - - - Solar panels absorb radiant energy from the sun and use it to heat water or produce electricity directly.
        
        Large area, solar panels are expensive, variable amounts of sunshine
    - - Steam comes from hot underground springs
    - - A river fills a lake behind a dam. Water flowing turns generators.
        
        Deep drilling is expensive and difficult
    - - Tides fill and empty a lake behind a dam. Water flowing to and fro turns generators.
        
        Risk of flooding, expensive, few areas suitable
    - - Generators driven by turbines
        
        Spoil landscape, large empty spaces required, noisy, winds vary
    - - Fuels are made from plant or animal matter; produce methane gas used in a thermal power station
        
        Environmental damage, huge areas of land needed to grow sufficient plants
      - Very concentrated source
    - - Generators driven by wave motion
        
        Difficult to build
  - - - Fules are burnt in a thermal power station
        
        Supplies are limited, pollution
      - Very concentrated source
    - - Fuels are used in a thermal power station.
      - Extremely concentrated source
      - Very dangerous waste, expensive to build and close down, high safety standards
