- - - - Unit : m/s^2
      - a is constant
        
        a= -g
      - Free-falling object
        
        acceleration due to gravity, g= 9.81 m/s^2
    - - Δx= x2 -x1
      - Unit :m
      - Differentiate x will get v, Integrate v will get x
    - - Differentiate v will get a , Integrate a will get v

        Velocity of object b relative to a = Velocity of object b- Velocity of object a
      - simple addition and subraction
        
        By using Pythagorean Theorem
- - - - Example: Torque
        
        T = F x r = (F)(r) sin θ
      - A × B = [(Ay)(Bz) - (Az)(By) ] i + [(Ax)(Bz) - (Az)(Bx)] j + [(Ax)(By) - (Ay)(Bx)] k
        
        Obtained by using determinant of matrix
      - A × B = AB sin θ
    - - Example : Work done
        
        W = F∙d = (F)(d) cos θ
      - A ∙ B =(Ax)(Bx) + (Ay)(By)+ (Az)(Bz)
      - A ∙ B = AB cos θ
- - - - acceleration
- - - - Resolve all vectors involved into x and y-components by using trigonometic functions (sine and cosine and tangent)
