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.
Pulling downward on the rope generates friction between the rope and the climber's hands, allowing the climber to push against the rope and move upward. This technique is known as "prussiking" or "ascending" and is commonly used in rope climbing situations to ascend a fixed rope efficiently.

What if the ribs pull upward and downward?
If the ribs pull upward, it can help expand the chest cavity for inhalation. If they pull downward, it can assist in compressing the chest cavity for exhalation. Both movements are important for breathing efficiently.
When a rockets lifts off the ground the net force is in an upward direction Is the upward pushing force greater or lesser than the downward pull of gravity?
When a rocket lifts off the ground, the upward pushing force (from the engines) is greater than the downward pull of gravity, allowing the rocket to overcome gravity and lift off into the air.
When a rocket lifts off the ground the net force is in upward direction. Is the upward pushing force greater or lesser than the downward pull of gravity.?
Greater
What happen when the downward pull of gravity on an object is equal to the upward force of water?
When the downward pull of gravity on an object is equal to the upward force of water (buoyancy), the object will float at a certain level in the water. This is known as the object being in equilibrium, where the forces are balanced and there is no net force acting on the object.
Can you pull the gravity upward to make material move?
The Newtons theory of Gravitational Forces would apply. ---------------------------------------------------------------- However you cannot change the downward direction of gravity on Earth. Everything is being pulled towards the centre of the Earth. It is true, however that the gravitational pull is strongest at the Earth's surface, and the pull is less atop a mountain or down a deep shaft of a mine.

What is upward pull?
ITS LIKE WHEN THERE IS A STICK STUCK DOWNWARD INTO THE GROUND AND YOU WANT TO TAKE IT OUT. YOU WILL PULL IT UPWARD. Sorry for capitalisation.. Hope this helped, :D

Is the upward pushing force greater or lesser than the downward pull of gravity?
The force on you, if you are stationary, exactly balances gravity.

less than three y.o pull pinna down and back

Why do falling objects move faster than objects going upward?
Falling objects are accelerated by gravity, while objects moving upward are being decelerated by gravity. Gravity pulls objects downward, increasing their speed, while it opposes the motion of objects moving upward, decreasing their speed.
How do you make a Lego car move without pushing it?
Blow on it. Pull it with a string. Place it on a downward slope.
When a rocket lifts off the ground the net force is in an upward direction. Is the upward pushing force greater or less than the downward pull of gravity?
The upward pushing force is greater than the downward pull of gravity in order for the rocket to lift off the ground. This excess force allows the rocket to overcome the force of gravity and accelerate upwards.
What is reached when the downward pull of gravity is equal to the upward push of air resistance?
The object would stop falling. This is what allows things to float, and what keeps planes in the air.
