No freewill

Is this a homework assignment?

When I put my sims in free will mode they cheat on each other, go to bed at 2pm, wash up at 5am and order pizza for breakfast

Explain what you mean.

Well this is just my theory. If you could take the exact position/trajectory/speed/acceleration of a particle, you could calculate using some pretty basic maths where it will end up in a second's time. That particle must end up in the position you calculated, it would be against the laws of physics for it not to. If you did the same for 2 or 3 particles that are heading towards each other, you'd be able to use their values to calculate when/where they'd collide and how they'll continue moving after the collision. Then when you extrapolate that, we're nothing more than huge masses of particles that must also follow those same mathematical rules of physics. If you somehow knew the position/trajectory/speed/acceleration of all the particles that make up you and everything that affects you (pretty much the entire Earth and far beyond), then you could calculate using the same basic maths where they'll all end up in a second's/day's/year's time. Even if you were aware of this there'd be nothing you could do to change the outcome since to do so would mean to violate the laws of physics.

You'd need to define free will first, as there are different interpretations of what it means. I can't argue against something if I don't know what it is.
