Mkuu soma hapa utapata mwanga kidogo,pia fungua hiyo link kwa maelezo zaidi ya kitaalam,hapa nimeweka kipande kidogo cha maelezo kutoka kwenye website husika:
Are you asking why the car accelerates faster than the bike at the same speed?
It's because the car's engine has a lot more power than the legs of the biker. The car is likely to have over 100 horse power while the biker doesn't have even 1. Not to mention the torque difference.The car is easily 100x more powerful than the biker.
