The Circumference Of A Ball

The circumference of tennis ball is 21cm  

The tennis ball took 0.29 seconds to drop and the netball took 0.22 seconds to drop.

A basketball falls faster than a tennis ball because it has more air and it is bigger and the tennis has less air and it’s lighter so it takes longer to fall.

What I thought was going to happen was the netball was going to drop faster and the tennis ball will take longer to drop and I was right.
