mass/ gravity /coefficients of friction

yuusaku

I've heard that putting some weight at the rear of a FWD would help, since most FWD weight distribution is usually light on the rear...

I personally have driven both FWD with(couple bags of sand) and without weight in trunk on snowy road...feels similar...

can anyone confirm this myth?

落雪﹐架車越重越好﹖定係越輕越好﹖

Everything else being equal (with identical weight balance, in particular), you want minimal mass, but maximum weight (b/c weight = downward force, which in turn provides friction -- which is grip).

In a typical everyday case, having less mass would make it easier to drive in snowy condition.

recall my physics11. (if i am right) force of friction = coefficient of friction x mass x gravity x cos(θ)
the greater the force of friction is, the faster your car can stop
sub in the numbers, then you will know the result

都要睇架車有几長同啲重量集中係架車边个部份喎！

Physics 11 is completely inadequate in accounting for real life situations because of all the assumptions it makes.

But I think it's good enough for what we're talking about here.
