Tennis court geometry question

[deleted-341360]

A fellow tennis player tells me I don't have to adjust my serve when playing on courts that have different slopes. I played on a level court for years and now suddenly I'm playing on courts that have a significant end-to-end slope of 1%. This means one end of a 78' court is over 9" higher than the other. When serving 'uphill', many of my serves hit the net because it feels like it's 4.5" higher (the net being hung at half the court length). When serving 'downhill', many serves go long. The question is whether there actually is an 'uphill' and 'downhill' in reality. Theoretically speaking, in reality, should my serve need any adjustment? Or am I just having (as my buddy suggests) 'perception issues'? After all, my feet are matching the new slope as I stand to serve. Thanks for any help with this!

Hi Shangster,

It sounds like your tennis question isn't related to a K-12 science fair project. These forums are specifically for K-12 students, parents, and teachers working on science fair projects, so a different set of online forums would be better able to help you.
