Forces and Energy - Coggle Diagram

- - - - what?
        
        when a force is applied to an object off-centre, so the object turns about a point that is called the pivot
      - when force is applied at a perpendicular distance furthest away from the pivot, the turning effect ↑
      - when force is applied at a perpendicular distance closest away from the pivot, the turning effect ↓
  - - - gravitational force
      - magnetic force
    - - friction
- - - - stored due to an object's height from a reference point (aka the ground) in a gravity field
      - amount depends on...
        
        mass (larger mass = larger GPE)
        
        vertical height (larger VH = larger GPE)
        
        gravitational field strength (larger GFS = larger GPE)
    - - energy stored in an elastic material (eg ruber band/spring) when it is stretche/compressed
      - the greater the amount of extension/compression, the greater the ampount of EPE stored in the object
    - - when energy is stored in chemical bonds
      - eg. food, fuels like batteries/petrol
  - - - speed: faster = more KE
      - mass: larger mass = more KE
  - - - total amount of energy before and after the change reamins exactly the same (amount of energy has been conserved)
    - - energy cannot be created or destroyed
      - energy can only be converted from one form to another
- - - - surfaces can be of any state
- - - - pressure ↑ when area of contact ↓
      - pressure ↓ when area of contact ↑
    - - pressure ↑ when force ↑
      - pressure ↓ when force ↓
- - - - thus, object will remain at rest / move with a constant speed in a straight line
    - - Thus, the object will undergo an acceleration (i.e. a change in speed and/or direction of motion
