Ir probably goes down faster if its heavier. If the ball was as light as a balloon, would it go faster? OF course not. So, a heavy ball would go MUCH faster down a hill.
Yes, among other variables.
No, it does not.
there are no slow moving photons, they move at speed of light.
Yes, it does. Although it does depend on what material the ball is made of, for the most part, yes. If you rolled a 5 pound ball made of rubber, with a circumference of 6 inches, it would go less far on a flat plane than a 5 pound rubber ball with 12 inches of circumference.:)*correct me if I'm wrong guys*Visit my website at www.freewebs.com/thebladeoffate
chlorine not the answer
Yes, it is normal; a great surface area improve the speed of dissolution.
The size of a ball does affect how fast it rolls. Surface also play a major role in how fast a ball will move.
if there are hole you will fall and lost your speed but on the straight surface you will get more speed
no
this project will not work for a science fair project i tried
Yes, that is true because of kinetic energy, If something is heavy and you roll it down fast, then kinetic energy builds up.All other things being equal the mass of the ball has no effect on its acceleration. A fact discovered by Galileo.
Temperature and surface area
The fast ball sport is baseball, a fast ball is basically when a pitcher just throws the ball staight at the strike zone.
fast ball
The ball speeds up as it travels to the ground as gravity pulls it down to make it go fast.

10 meters per second due to gravity
I am assuming you are talking about tennis. On a grass surface, the ball will bounce fast. On clay courts, the ball will bounce slower than on grass. On a hard court, the speed of the ball bounce will be in between clay and grass.
