It depends on many factors. How will the tennis balls be propelled? Will you hit both with a racquet? Will you shoot them from a potato cannon?
Tennis ball
Tennis ball, its heavier.
It depends. If a tennis balls are hit with the same amount of force, then the dry tennis ball will travel faster and farther. However, if the two tennis balls begin traveling at the same speed, then the dry tennis ball will slow down more rapidly than the wet tennis ball. The reason is the added mass of water. It would take more force to make the wet tennis ball fly as fast as the dry, but the added mass also requires more force to slow down the wet ball.
Probably.
The gas inside of a tennis ball will usually settle when frozen. In most cases this means that it will either freeze or cause the ball to shrink.
Technically, a frozen tennis ball will not bounce well because of the temperature. The elasticity is one of the factors in which a ball bounces and when things are colder, there isn't as much elasticity, so it will not bounce as well. Therefore, a dry ball (as long as it wasn't frozen in a container) will bounce better than a frozen one.
A tennis ball is fuzzy, has more drag, and falls slower. A soccer ball is smooth, has less drag, and falls faster.
Baseball
i think a football travels faster because you can throw a spiral and that goes faser
because the tennis has more bounce in it your welcome
golf is faster than both but tennis is faster than baseball
Yes, of course. The material a tennis ball is made out of is porrus. That is why tennis balls go flat.
