Q. 145.0( 2 Votes )

We know that friction depends upon mass of the body when we roll down an iron ball and a football on the ground, which ball will travel more distance? Why?

Answer :

Mass of an iron ball is much greater than that of a football. As friction depends upon mass of the body, the frictional force on the iron ball must be greater than that of football and as friction force is an opposing force, the distance travelled by the football must be greater than that of the iron ball.
