- - - - Slope: (nothing!)
        
        Area bound by the line: change in velocity
        
        the slope for the distance over time graph gives us the velocity of the object we are anlaysing. While the slope of the velocity vs time graph gives us the acceleration of the object
        
        the area of the velocithy vs time graph is the displacement, while the area of the distance vs time graph is nothing
- - - - mu (sub) s: coefficient of static friction
    - - mu (sub) d: coefficient of static friction
- - - - This means it can have a negative or a positive value
      - If an object travelling to the right has positive momentum, an object travelling to the left (in the opposite direction) has a negative momentum
      - The negative or positive directions are defined by the observer on a case-by-case basis
      - The SI unit for momentum is kg m s−1
- - - - W: Work , F: force, s: displacement
  - - - GPE= (mass) (gravitational field strength) (change in height)
      - EE= 1/2 (elasticity constant) (change in position)^2
      - KE= 1/2 (mass)(velocity)^2
    - - .
        
        SITUATION: A SPRING IS BEING COMPRESSED IN ITS INITIAL STATE, THEN LAUNCHED TOWARDS THE AIR IN ITS FINAL STATE. (ASSUMING AIR RESISTANCE IS NOT NEGLIGIBLE)
        
        final state: measures the amount of energy during that point of time. In this case, 2 bars for GPE, 1 for KE, and 1 for Interesting Energy.
        
        .
        
        initial state: measures the amount of energy in this point of time, in this case, having 4 bars of elastic energy
      - it measures the amount of energy a system has
