No Limits

Bungee jumping is what is considered an extreme sport. It is basically jumping off a platform with an elastic cord tied to the jumper. As the cord is stretched resistance slows the person before they reach the ground. Energy stored in the cord is reduced incrementally as the jumper is oscillated by the rebounding properties of the cord until they come to a state of equilibrium.

Hooke’s Law of Elasticity

One of the most useful physics laws that can be used to explain bungee jumping is Hooke’s Law of Elasticity. Robert Hooke was a British physicist from Great Britain. He lived during the 17th century and created a law that explained the restoring force of a spring.

Hooke’s Law of Elasticity can be expressed as F = -kx. In this formula F represents the amount of force required to restore elastic material to its position of initial equilibrium, k represents the spring constant, which is a constant force and x represents the distance between the fully stretched spring to the initial position of equilibrium.

Potential Energy

The principles of the bungee jumping sport rests in the potential energy that is stored in the spring or the elastic cord used in the sport. The potential energy of the cord can be expressed as U = .5kx^2. This formula will always produce a positive result, as opposed to the Hooke’s Law of Elasticity which has the potential to have oscillating results on both positive and negative sides of a graph.

Oscillation

Oscillation is another physical characteristic of the bungee jumping experience. Oscillation of the jumper can be expressed with the frequency formula: v = 1/(2 X pie) X the square root of (k/m). This formula can be graphed to demonstrate the position of the bungee jumper over time.

Mountain Climbing is a challenging sport that requires mental commitment , fitness, strength in your arm and legs that will allow you to handle the degree of difficulty that the climb demands. Mental commitment is crucial otherwise your strength is unchanneled. When you are faced with difficult obstacles you have two choices: give up or do it. Climbing enthusiast claim that the sense of achievement and satisfaction in reaching the top of a climb is terrific. You have challenged yourself and won and this is why these daredevils love it.

Rock Climbing began as a man’s sport. This has changed in recent years as ever increasing numbers of women have become involved. The first women climbers were involved in mountain climbing and rock climbing was a part of that. The major difference in mountain climbing and rock climbing is that the mountain climber is seeking the easy way to ascend to the top of the mountain while the rock climber is looking for the hardest way. However, sometimes rock climbing is the only way on certain sections of the climb. So, when women began to climb mountains, they naturally began to climb rocks as well.

Mountain Climbing Journals

Take a minute to give some consideration to your most recent mountain climbing experience. What sticks out in your mind? Now think about the first time you ever went mountain climbing. Undoubtedly, you remember few things about the geography, people you went with, particular mountain climbing routes and spectacular views. The experiences you’ve forgotten are lost to time. If you keep a mountain climbing journal, this won’t be the case.
