Newton's Three Laws: Skeleton
Emma Camp & Jonathan Henderson
Skeleton: Introduction

Skeleton is a winter sport similar to luge, in which a person rides a small sled on a frozen track, headfirst.
Skeleton originated in St. Moritz, Switzerland, as a spinoff to a popular British sport, Cresta.
The sport was named for the bony appearance of the sled.
Sledders travel at speeds of 75-85 mph. (33.5-38 m/s)

Newton's First Law
Newton's Second Law
Acceleration is produced when a force acts on mass. The greater the mass, the greater the amount of force needed.
In skeleton, sledders are able to reach up to 85 mph. They do this by pushing thier sled across a track, accelerating it. The greater the mass of the sled, the greater the amount of force required to push it.
f=ma
A skeleton sled has a mass of 40 kg. If the skeleton sledder accelerates it to 10 m/s, what is the amount of force he he used.
f=40 kg. x 15
f= 600 N
Newton's Third Law
For every action, there is an equal and opposite reaction.

The force of the sled and sledder on the ice creates an equal and opposite reaction from the ice, otherwise, the sled would fall through the ice.

An object at rest tends to stay at rest; an object in motion tends to stay in motion, unless an external force is applied to it.

Sledders begin the race by running, pushing the sled on the ice with them, they then jump on the sled, and ride it for the remainder of the race.
This shows Newton's First Law, because the sled does not move until the sledder pushes it. The sled will stay in motion until the friction of the ice slows it down.
