Hitting the net full on. Hitting the net and the ball carries on over it. Foot crossing the line when you hit the ball. Hitting the ball full on and it does not land in the field of play.
There's only one way stepping inside the tennis court before you actually hit the serve, but it only happens if you are in your swing and step in.
three kinds of faults are normal fault, reverse fault, and strike-slip fault.
fault
A symmetrical fault is a fault where all three phases are experiencing the same thing. This is also called a three phase fault, since all three phases are involved.
Tennis consists of the best of two out of three

It can bounce once, after the second bounce its a fault.
Look at the picture.
normal reverse strike-slip
Three phase fault is the most severe.
The three types are Line to ground faults line to line fault double line to ground fault three phase line to ground fault
In power engineering, specifically three-phase power, a symmetric, symmetrical or balanced fault is a fault which affects each of the three-phases equally.In power engineering, specifically three phase power, an asymmetricor unbalanced fault is a fault which does not affect each of the three phases equally.for these reasons thus symmetrical faults are more severe than the former.
