The first difference would be the name, the second difference is the way the look.
In terms of functionality, I would not be worried about using Wrestling knee pads in volleyball, but there may be a difference when using volleyball knee bads while wrestling. Volleyball knee pads are designed to be flexible to allow a lot of movement, but you do not spend that much time on the floor as compared to wrestling.
there is no difference
A mini volleyball small and a volleyball is much bigger
volleyball uses a volleyball and basketball uses a basketball.
One is faster than the other!
outdoor volleyball is played by the beach. Inside volleyball is played by the gym.
The one big difference is that one is played inside and on court and is played outside on sand. Another difference is that you have 2 people playing rather than 6 on a regular game of volleyball inside!! And that's the difference between beach volleyball and indoor volleyball. Sources: I have played volleyball for 10 years!!
The difference between beach volleyball and sitting volleyball is that on the beach you do not sit to play volleyball where as obviously in sitting volleyball you would. Also I believe that usually disabled people play sitting volleyball. But I am quite sure that sitting volleyball could be played at the beach.
The surface you're playing on. (It's also different from beach volleyball!)
well flagrantly, beach volleyball is played on the beach and regular volleyball is played indoors such as in a gym
Hockey is played on ice and volleyball is not. Hockey is played with a puck and volleyball is played with a ball.
Beach volleyball has two players per team and doesn't rotate. Oh, and its in sand :)
The net of tennis is shorter then a net for volleyball.
