I dont want to answer the question for u, cuz I will be doing the work and you will be getting class credit for it. That’s no way to expand your brain and problem solve yourself.

Hint: Everything should be a constant in the experiment…and ONLY one thing should be a variable.

ex: take a bike with the old bearing system..and then take that SAME bike with the new bearing system. The constant is the same bike, same bike rider, same everything…the only thing that chaged is the bearing.

The same should hold true for the test track..everything on that track should be a constant. Same distance..same starting point, same ending point…and dont forget the same stop-watch…haha

I hope that’s enough info for you to get your mind in the right direction…and figure the rest out. Good luck!

What good would someone telling you the answer do? If you are struggling, you need to talk to your teacher about it. There won’t always be someone around to give you answers so you should learn to take care of things on your own now.
