Investigating the relationship of projectile range and projectile motion using a ski jump.

Introduction

As we all know ski jumping is a worldwide sport in which athletes skate down a slope ramp, gaining speed that throws them in the air that makes them land some distance away. The distance travelled at the time when the jumper leaves the ramp, until he reaches the ground is known as the jump range. This interesting and challenging sport involves a lot of physics behind it. Kinetic energy, gravitational potential energy, motion, speed, height, time, distance and the athlete's ability to reduce air resistance to their body are all factors that determine the athlete's performance. This experiment represents a ski jumping slope through which we will investigate and demonstrate how physics can be used by ski jumpers to increase their range in the jump.

Aim: My aim of this experiment is to explore the relationship between the launch height and the range of the jump. I will use the my knowledge of physics knowing that gravitational potential energy can be converted into kinetic energy and using the equations ?Egrav = mg?h for gravitational potential energy and Ek = 1/2 mv2
