ive always been interested in calculations, so i wanna try to calculate watt but im stuck(adsbygoogle = window.adsbygoogle || []).push({});

bear in mind this is a pure hobby for me and i am far from a math genious

in this example i use a car

here is how far i have come

it accelerates from 22.2m/s to 33.3 m/s in 7 seconds

to calculate acceleration you do like this

highest speed-lowest/time 33.3-22.2=11.1 11.1/7 is almost 1.58

giving the car acceleration of 1.58m/s^2 so far so good

-----------------------------------------------------------

next is calculating work

work= mass*acceleration^2

so if the car is 1200kg(newton)

then we take 1200* (1.58*1.58) = 2996 joules (this is correct i hope)

--------------------------------------------------------------------------

and this is where i get stuck because the formulas i find state that watt=work/time

2996joules/7sec is obviously wrong.....

can anybody help me?

cheers/Johan
