Which one falls to the earth faster: a feather or a bowling ball? Neither.


Brian Cox explains why two falling objects will reach the earth in the same time where they fall in a vacuum chamber. Basically, any two falling objects will fall at the same rate with g as the acceleration.

You can easily explain this if you know the formula h= 1/2 gt^2. H is the height of drop, t is time, and g is the gravitational acceleration. Nowhere does it show it is dependent of mass.

You see the feather falling slower due to the friction with air, but for two random big enough objects you will see that they fall at the same rate. Nice work physics 😀
