  1. BOBSLEDDING

  2. Things you need • Two-man: minimum 384 pounds (170 kilograms) when empty, maximum 860 pounds (390 kilograms) with crew and equipment. • Two-woman: minimum 284 pounds (170 kilograms) when empty, maximum 750 pounds (340 kilograms) with crew and equipment • Four-man: minimum 463 pounds (210 kilograms) when empty, maximum 1,389 pounds (630 kilograms) with crew and equipment

  3. Rules/objectives • The whole point of the event is to run the track as fast as you can to beat the other teams times.

  4. How physics are involved

  5. How physics are involved: Friction • Something that is pulled against something else like gravitation pulling the bobsled being pulled to the surface of the ice. There's not much friction between smooth metal and ice, but even a tiny amount will slow the bobsled down. Each bobsled's runners scrape and scar the ice on the way down, so teams that race later in the day have more friction to overcome so they have a slower time.

  6. How physics are involved: acceleration • Acceleration is applied when the bobsled goes around a sharp turn or down a hill for the bobsleds speed to increase.

  7. How physics are involved: Gravity • Gravity is the force that pulls objects with mass toward the Earth which is why objects tend to accelerate while going down hill.
