Question

why do marble and the matchbox travel at different distances​

Answer 1

Answer:

The surface area of matchbox is more than the surface area of marble.As the frictional force acting on an object is directly proportional to it's surface area ,the matchbox lose it's velocity and covers less distance than the marble.On the other hand due to the spherical shape of marble, very less area of marble is in contact with ground and hence very less frictional force acts on it.therefore there is a difference between the distences covered by the marble and matchbox.
