I did a physics prac about Galileo's idea that horizontal velocity will not impact vertical velocity, which is to say that i rolled a ball from a ramp, off a table so it had initial velocity before it fell to the ground, then i dropped a ball from the same height and I measured the time it took for them to reach the ground by using a strobe like and a camera. I don't know how to write a hypothesis for my report, can any one help or suggest what I should write?
Thanks guys
