Question by shahabsy · May 07, 2014 at 07:32 PM · physicssimulationroll a ball

Hi guys, I need your opinion regarding physics simulations in unity.

My question is: Can we do real physics experiments in unity? like if we roll a silver ball on a wooden table in real life. and when it stops, measure the ball speed, distance and time etc. Then we setup the same scene in unity and do the same experiment , would both experiments results and measurements will be the same?

No it wouldn't be the same, the wooden table in real life could have any number of defects, grain lines, knots, etc that would affect how the silver ball would navigate down the table. Capturing every single attribute of the air, dust in the room, on the table etc would be nuts.

No.

Even if you could exactly model the real world conditions, Unity is doing a step-wise approximation. The real world is continuously integrated.
