a drop shot is a shot left very short, close to the net so that the receiver must approach the net to return it.
One of the major disadvantages in using a drop shot is that it is one of the hardest shots in tennis to master and do correctly. While playing in a match though the main disadvantage is if the player you are challenging is quick enough to get the drop shot and get a good angle which then it can be impossible to return the shot sometimes and then if the player retrieves the drop shot and the player returns the drop shot return the player who does the drop is very vulnerable for the next return.
It depends. A shot with backspin will drop a lot faster then a topspin or flat shot.
A high tennis shot is called a "lob"** By a "high tennis shot" I assume you mean a shot that YOU hit
