What is a transformer? explain how a transformer works including specific details

Transformers are bots that "transform" into cars and giant mega robots. Im personally not a big fan of transformers but it is called transformers because it can transform into other non-living objects. 

 We will use formula for the orbital velocity of Venus, which is v = 35.02 km/s. 
    An average distance to the Sun ( In kilometers ) is:
    R = 0.723 * 149,579,871 km= 108,150,260 km.
    Than we will calculate the orbital period ( T ).
    v = 2 π R / T
    T = 2 π R / v
    T = 2 * 3.14 * 108,150,260 km / 126,072 km/s
    T = 5389.75 s ≈ 224.5 days
    The orbital period of Venus is approximately 224.5 days.
