Question

A horse has more kintic energy than a dog running at same speed why

Answer 1

We know that kinetic energy acquires for mass, velocity of a body.

Hence, here also horse weight is actually much than weight of dog, so it has more kinetic energy than dog even if they have same speed.

Answer 2

The answer of your question is given below :-

* Kinetic energy = ½mv²

Given = speed is same

Then, the value of kinetic energy will be different because of the difference in the mass of horse and dog ( from above formula ). Horse has more kinetic energy than a dog running at a same speed.

Hope it helps you
