Rolling sphere slows down becoz of friction........

DebjaniSutradhar: plz mark brainliest....
0411kaushik: its 3 mark question
DebjaniSutradhar: hmm
DebjaniSutradhar: ok let me explain then...
DebjaniSutradhar: wait..
DebjaniSutradhar: When you roll a ball on the ground, the electrons in the atoms on the surface of the ground push against the electrons in the atoms on the surface of your ball that is touching the ground. A rolling ball stops because the surface on which it rolls resists its motion. A rolling ball stops because of friction.

My friend, the truth is that nothing is absolutely smooth. Everything is someone rough on different levels. So ultimately when two rough edges get hooked together the kinetic energy breaks the hook of the static object for example a football moving on the ground. This is where friction comes in through the object (here the ball) continues to be in a state of motion, yet due to the kinetic energy lost in breaking the speed (or velocity) of the ball decreases. The continuous loss of the kinetic energy caused due to continuous reption of this book breaking process results to continuous decrease in the speed of the ball. Ultimately the ball comes to rest and stops.

In concise the friction and the loss of kinetic energy are the two factors responsible for this.

HOPE THIS HELPED!!
