How did the pulley affect the amount of force needed?
A pulley is a force multiplier. (it swaps force for distance).
How do the length and the height of a ramp affect the amount of force needed to raise a load?
The height and length give an inclination angle. If you assume a straight ramp, this angle is arctan(height/length). Beware: length is measured over ground, i.e. horizontally. The force needed to raise a mass over such an ramp is sin(angle)*mass*gravitational_constant Beware: friction neglected here, example: steel ball rolling up a extreme hard, flat surface. The force of gravity acts vertically downwards on the object, and it is the component of this force down the slope that has to be overcome in order to raise the load, plus any frictional force opposing the movement. The applied force will be least if the force is directed parallel to the slope
How does the number of supporting ropes on a pulley affect the amount of force needed to lift the load?
The more pulleys and ropes you add the easier it is to lift
How does moving fulcrum on a lever change the amount of force needed to move an object?
how does moving a fulcrum on a lever change the amount of force needed to move an object
How does the length of a wrench affect your force?
more length more torque, force applied remains the same
How did the pulley affect the amount of force needed?
A pulley is a force multiplier. (it swaps force for distance).
How does making slope of an inclined plane less steep affect the amount of force needed to move an object?
the less steep it is the less force you will need
Can the number of pulleys affect the amount of force to lift a heavy objects to a high place?
Increasing the number of pulleys divides the force required to lift up a heavy object; increasing the number of pulleys decreases the force needed by the person (or motor) pulling the first end of the pulley system. However, it is important to know that it does not affect the total work needed to lift up the object. As the force is decreased, the distance of rope needed increases to compensate for a conserved amount of work required for the load to be lifted.

How much force is needed to knock out a bear?
the amount needed is the amount that's taken by the bear
How does the number of supporting ropes on a pulley affect the amount of force needed to lift the load?
The more pulleys and ropes you add the easier it is to lift
How does length of spring coil affect the force constant?
The force constant is unaffected; It is a constant.
How does moving fulcrum on a lever change the amount of force needed to move an object?
how does moving a fulcrum on a lever change the amount of force needed to move an object
How does making the slope of an inclined plane less steep affect the amount of force needed to move an object?
It requires less force to move an object up an inclined plane if the slope is less steep.
The amount of needed to make an object change its depends on the of the object and the required?
. The amount of Force needed to make an object change its motion depends on the Mass of the object and the Force required
What is The amount of force needed to move a lever of a given length?
That depends on the weight of the load on the other end, the material of which the lever is constructed, and how much of the lever is on each side of the pivot.
How do you decrease the amount of force needed to do work?
Decrease friction.
