Hai Sindhuja


Nice doubt, how you get this doubt. Have you performed this experiment in your home. if yes answer my questions


1)What type of slope

a) smooth surface

b) rough surface

2)What are the balls weights


3) How you are saying that, bowling ball rolls faster than tennis ( have you seen this practically)


4)what is the volume of the balls



In my imagination i am considering the bowing ball is solid and tennis ball is a hallow space ball.


These to are in circular shape, so moment of inertia place a key role


Moment of inertia:

The tendency of a body to resist angular acceleration, expressed as the sum of the products of the mass of each particle in the body and the square of its

perpendicular distance from the axis of rotation.

 Symbol: I

I = mr^2

The moment of inertia of different shapes


velocity, v, of the bowling ball is greater than that of the tennis ball; just because one is hollow and one is solid.

Thank you krishna. Actually my friend asked this question.he did it in a normal surface(neither too rough nor smooth) and the two balls are same size. The bowling ball is solid and smooth and tennis ball is soft and fuzzy.The volume of the two balls is same.

Because bowling balls are bigger than a tennis ball
