Forces
Here are some forces that can act on a
climber while on a vertical cliff side.

Here we can see the pull of the rope, or
tension, pulling away from the climber. The friction
force acting on the foot of the climber is caused by the
movement of the foot downward. Friction forces always
act in the opposite motion of direction. The push of the
cliff is also called the normal force which acts in the
direction perpendicular to the surface of the cliff.
Finally the pull of gravity is caused by the acceleration of
gravity multiplied by the weight of the climber.
When a climber falls, they receive a Shock
Force.
