"If two balls, of different weight where put on the same incline, would they roll down together? Explain using Newtons laws." I tried it, and as I thought, the heavy one went faster, but why? A=F/m ...but force is said to be "mass x gravity (9.8N) x sin (the angle)" but divided by mass and its just gravity x sin angle....so they roll together? I'm confused. Please help me ASAP!
