One thing I enjoy as a new physics student is using formulas. I have been playing with the fundamental formulas in terms of units rather than their names. That is instead of a=v/t m/s/s=(m/s)/s or v=at m/s=(m/s/s) x s m/s=m/s Simple maths yea, but when im getting to the bigger formulas im having trouble, perhaps they just dont work the way i am thinking but if someone could enlighten me that would be great.. S=(1/2)at^2 m=(1/2)x(m/s^2)x(s^2) m=(1/2)x(m) why do i get m = half m? v^2 = 2as m^2/s^2 = 2(m/s/s) x m m^2/s^2 = 2 x m^2/s^2 m/s = 2 x m/s again, there is a x2 factor there. am i just thinking about this too much?
