twice
no
Not up.
Test is!. A tennis ball is going to bounce higher.
Twice
I believe a basketball
When you throw the tennis ball, it flies for a distance before dropping down because when you throw the tennis ball, you use force, which is transferred to the tennis ball, which then converts to kinetic energy (movement energy), to allow the tennis ball to go far.
going to hit
tennis regulations include but are not limited to: foot faults - you cant step over the line before you serve the ball you cant touch the net until the point is over the ball cant bounce twice before you hit it no distracting the player during the point(yelling, etc)
If you mean by hitting the ball twice, then yes.
A volley in tennis is a shot that is hit before the ball bounces on the ground.
Sometime before 1480
