प्रश्न
Give reasons for the following A horse and a dog are running with the same speed. Which one of them has more kinetic energy than the other.
उत्तर
A horse has more mass than a dog. As both are running with the same speed.
M1 of the horse is greater than M2 of dog
∴ K.E. of the horse is more than K.E. of dog
