Kinetic energy of a snowball will increase as it <span>rolls across the lawn and gains mass. We already know that Kinetic energy is directly proportional to speed. We can express kinetic energy by the formula
Kinetic energy = 1/2 mv^2
Now as the mass increases and the velocity remains constant, the kinetic energy of the snowball is bound to increase. I hope the explanation has helped you.</span>
What would most likely reduce the bias present in Elias' experimental design would be to not ask just the members of his high school team to be the subjects because they represent a very specific group of people. It would be much better to use a random group of people and have them do the same thing.
