Momentum - Coggle Diagram

- - - - this formula is derived from F=MA
- - - - example. what is the momentum of a 1000kg car moving east at 20 m/s
  - - - a 1500kg truck going 10 m/s hits a 1000kg car going 15 m's. what is the final momentum of the cars in which stick together after the collision.
  - - - you must add vectors in different directions using the component method. and trig :)
        
        a 16 kg grenade is rolled at 10 m/s and then explodes into 2 smaller pieces in which are flung 20 degrees ne at 10 m/s and the other is flung downwards 10 degrees at an unknown speed find the velocity.
- - - - open system
        
        External forces and mass both affect this while both of these are not contained.
        
        stove top as the stuff put on a stove top can be moved and energy leaves
      - Closed system
        
        a system in which energy is not contained but mass cannot leave
        
        a kettle is an example of a closed system as mass cannot leave while energy is able to vent out.
    - - A system in which external forced cannot act upon, energy is unable to leave while momentum is conserved
        
        the universe and a thermoflask are good examples
        
        both of these things contain everything while nothing on the outside affects it
      - m1v1+m2v2=mv
  - - - both momentum and energy is conserved
        
        when you throw an ball onto the ground and it bounces back up to your hand. there is no change in kinetic energy therefore it is elastic
    - - momentum is conserved but energy is not.
        
        when 2 cars hit each other and stick together henceforth becoming 1 object but still with the same momentum
        
        m1v1+m2v2=mv
- - - - IT IS VECTOR
        
        AND ALWAYS CONSERVED
  - - - the formula was derived from F=Ma to account for momentum and was tunred into F(change in t) = change in momentum
