brotoWhoa somebody took a euclidian geometry class
shreddinthegnarrAlso, when you try to measure acceleration at an instant in time, you can't. The change in time at an instant is 0 therefore any rate is undefined. So when you're running or in a car, an infinite of undefined accelerations make up your acceleration.
SpssThink about 2 points. Practically, you could never get them to meet, because that would require infinite precision. also theoretically, if you did have the precision, they would never actually touch since they have no volume. There is nothing in a point- its only a marker of somewhere between here and there.
RJ_ResWhat if you had a pre-existing line and picked two points on it? I would say that they would meet then, since their position is defined by the line, which connects them.
SpssGood point (no pun intended) but you still have the same problem as the point and the plane; they will meet (per se) but they are both made of nothing so what is there to actually meet?
