The MythBusters run tests and experiments to find out whether or not dropping a penny from the Empire State Building will embed itself in the concrete or kill a person.

Alpine skiiers face the forces of gravity, friction, wind and air resistance as they travel fast down hill on their skiis.

Beakman (as Galileo) does an experiment where he drops an eggplant and a piece of paper at the same time to see which lands first. The first go around, air resistance causes the paper to float down. He then wads it up and tries again to show they will fall at the same rate to the ground.

Beakman challenge: use a hammer to break a ruler without holding the ruler. When Lester tries the first time, the ruler flips off the table. Beakman lays two pieces of newspaper on the end of the ruler and now the ruler breaks. Beakman explains this is because of air resistance. Without the paper, the ruler didn't have much to resist but with the paper, it has to push that paper away too and since you hit it so fast with the hammer, it doesn't have time and it breaks.

Galileo explains to his student that, if two balls are dropped at the same height, they will both hit the ground at the same time, regardless of their weight.
