Because the ping pong ball is hollow
It is easier to move a ping pong ball than a bowling ball because the ping pong ball has far less mass than the bowling ball. Since force = mass times acceleration, it will take far less force to accelerate (and thus move) the ping pong ball.
The official ping pong ball is a hollow sphere made of plastic and 20 mm across. The mass is measured at 2.7 grams.
Mass is a measurement of space taken up. Since a marble is not hallow like a ping pong ball is, it has a greater mass.
A golf ball has a greater mass than a ping pong ball. It therefore contains more matter.
ping pong ball
The golf ball has more mass. Mass is proportional to weight (Newton's 2nd law) and the golf ball weighs more than the ping pong ball, thus the golf ball has more mass.
no , it cannot
It has no special name, it is a ping pong ball.
A golf ball will fly further than a ping pong ball. The low mass/weight of a ping pong ball makes it more susceptible to air friction. This greater drag on the ball slow it down sooner than the golf ball.
The ping pong ball is made from celluloid.
