How does a pulley change the input force?
A single pulley only changes the direction of the applied force. A second or more pulleys on the same rope will multiply the force applied by decreasing the distance of the applied force. This arrangement is called a block and tackle. Two pulleys double the force and halve the distance the force acts upon the mass. Three will triple the force while reducing the distance by 1/3, and so on. If 1 pound of force is applied to a rope with four pulleys on it over the distance of 10 feet of rope it will raise a 4 pound weight 2 1/2 feet.

Levers explain how the force applied by a lever is affected by its distance from the fulcrum?
On the side on which the force is being applied, the distance and force are directly proportional. On the other side of the lever, they are inversely proportional. If 1 pound of force is applied to a lever at 1 foot on the left side of the fulcrum, the lever will apply 1 pound of force 1 foot from the right side of the fulcrum. If 1 pound of force is applied 2 feet left of the fulcrum, the lever will apply 2 pounds of force 1 foot from the right side. If 1 pound is applied 4 feet left of the fulcrum, the lever will apply 4 pounds of force 1 foot to the right of the fulcrum. If 1 pound of force is applied 1 foot left of the fulcrum, at 2 feet on the right side, the force will be 1/2 pound. At four feet, it will be 1/4 pound. Etc,
Does the type of shoe affect jumping or distance?
Yes, it can affect the distance that the athlete is jump.Why?Because the force that you apply on your legs transfer the the lowest part of your body,your feet,and if your feet are not properly suited that can affect the distance.
How does forces affects motion in football?
The same as everywhere else... If a force is applied, an object's velocity changes. In football, I would guess that the main forces involved (for the ball) are the force applied by player's feet (or other body parts), air resistance, and gravity.

When a horizontal force equal to its weight is applied to an object on a frictionless surface what is its acceleration?
9.8 meters (32.2 feet) per second2 horizontally, provided the exercise is performed on or near the Earth.
What is the mathematical formula for calculating work?
The mathematical formula for calculating work is: Work = Force × Distance × cos(θ) where: Work is the amount of energy transferred or expended; Force is the amount of applied force; Distance is the displacement of the object in the direction of the force; θ is the angle between the direction of the force and the direction of displacement.
When measuring torque is a two foot-pound measurement the equivalent of two pounds of force applied one foot from the pivot point or one pound of force two feet from the pivot point?
The way torque works, these two cases give the same torque, or twisting force, to the object at the pivot point. To find the torque applied, multiply the force by the distance. Obviously this is the same in the two cases you describe.
How many pounds of force is applied to man 250 lbs falling 3 feet?
The main force would be the force of gravity, which is 250 pounds in this case.
How fast is a car going that it takes 131 feet for it to stop?
It depends on the decelerating force applied by the brakes.

What is the difference between ft pounds and pounds ft?
There is no difference. It is (force x distance) or (distance x force). It is usual to express torque and moment of a force in pounds-feet and work done in foot-pounds but it is not mandatory.
159-weight 131-length equals square feet?
No. Force x Distance = Work done.
