A mountain climber faces challenges such as extreme weather conditions, difficult terrain, physical exhaustion, and the risk of avalanches or falling. These obstacles can make crossing between peaks dangerous and require careful planning and skill to navigate safely.

What forces act on a climber?

When climbing, a climber experiences forces such as gravity, friction between their body and the rock face, tension in the rope, and air resistance. These forces affect the climber's ability to ascend or descend safely.


A 900 Newton mountain climber scales a 100 meter cliff How much work is done by the mountain climber how long did this take in minutes if the climber used 88 watts of power?

The work done by the mountain climber is given by the formula: Work = Force x Distance = 900 N x 100 m = 90,000 Joules. To find the time taken in minutes if the climber used 88 watts of power, you use the formula: Power = Work / Time. Rearranging this, Time = Work / Power = 90,000 J / 88 W ≈ 1023 seconds ≈ 17 minutes.


Why does a rope climber pull downward on the rope to move upward?

The climber is actually pulling downwards on the rope. S/he is trying to pull the rope down or out of the ceiling but cannot do so. If you think of the climber just hanging there the rope has a tension upwards to counter the weight of the climber. If you are to move up then equilibrium must be broken and the net force on the climber must be up so the rope pulls the climber upwards. Of course, this pull is to do with action and reaction but the effect is the same.


What are the differences between a stair stepper and a stair climber, and which one is more effective for cardiovascular fitness?

A stair stepper mimics the motion of climbing stairs with pedals, while a stair climber has rotating steps that simulate climbing. Both are effective for cardiovascular fitness, but a stair climber may provide a more intense workout due to the rotating steps engaging more muscles.


What type of energy does a climber have falling down a cliff?

The climber has potential energy while falling down a cliff. As the climber is at a height, this potential energy is converted into kinetic energy as they fall due to gravity.
