the force on the load is the force exerted by the simple machine on the load. All simple machines involve a force on the load and an effort force.

Which direction will the load move if the force applied to the rope is greater than the force of gravity on the load?
I assume this is not a trick question of like the rope is not taut. If the rope is taut, the load will move to the combined force of the applied force and gravity, in the vector sense. In the simple case of the applied force being directly opposite to gravity, the load will rise straight up from the ground. If the applied force is perpendicular to gravity (that is, horizontal), the load will drop to the ground at an angle, depending on the sum of the two force vectors.
Why is a greater force needed to move a refrigerator than it's needed to move a book?
The formula for force is Force= Mass x Acceleration. Therefore, you have to use a greater force to move the refrigerator because it has a greater mass than the book.
How does moving fulcrum on a lever change the amount of force needed to move an object?

What instrument measures the force needed to move an object along a surface?
force-meterfriction
Is work the measure of amount of force needed to move an object a certain distance?
No, work is related to energy, not to force.
What is load force?
The load force is applying a force to move or hold an object that has weight.
What direction will the load move when you apply force downward in the pulley system?
The load will move upwards.
A force needed to blank an object?
A force is needed to move an object.
What are the 3 classes of levers?
Levers are classified into three types (first-class, second-class, and third-class) depending on the relative position of the fulcrum (pivot point), the point of applied (input) force, and the location of the load (output force). In a first-class lever, the fulcrum is between the input force and the output force, and the load is moved in the opposite direction of the applied force. Placing the fulcrum closer to the load gives an advantage of force (less force needed to move the load a shorter distance), while a fulcrum closer to the point of applied force gives an advantage of distance (the load is moved a greater distance but more applied force is needed). First-class levers include a crowbar, using a hammer's claw end to remove a nail, and a pair of scissors. In a second-class lever, the load is between the fulcrum and the point of applied force, so both forces move in the same direction. Less force is needed to move the load, but the load does not move as far as the direction over which the input force must be applied. Examples include the wheelbarrow, a bottle opener, and a door on its hinges. In a third-class lever, the input force is applied between the fulcrum and the load, and both move in the same direction. The amount of applied force is always greater than the output force of the load, but the load is moved a greater distance than that over which the input force is applied. Examples include a hammer driving a nail and the forearm of a person swinging a baseball bat.

What do fulcrums help?
A fulcrum is the point of tuning for a lever. Since a fulcrum is essential for a lever, it does not help but rather is needed. The lever and fulcrum are used to move or hold objects. Levers can be used change the amount of force needed to alter a system of load, lever, and effort. The position of the fulcrum determines the force needed to change the natural equilibrium. There are three classes of levers divided in accordance to the position of the fulcrum. The first class of lever is typically used in a gravitational field with a load at one end of the lever, the fulcrum closer to the load than the middle of the lever, and a force applied near the other end of the lever. The important point is that the fulcrum is between the two forces and on the opposite side. If the lever is longer on the force side, the force needed to move the load is less than the weight of the load, but the load travels a smaller distance than the applied force point moves. This would be used possibly to lift an heavy object. By placing the fulcrum close to the point of force, the load moves farther than the applying force. This can be demonstrated by observing a trebuchet (commonly referred to as a catapult) The second class of lever places the load and the force on the same side of the fulcrum with the load closer to the fulcrum than the applied force. An example of this is the wheelbarrow. Again, the force needed to lift the load is less than the weight of the load. The third class of lever places the force between the fulcrum and the load. Examples of uses for this are chopsticks or ice tongs.
Which way does the force and load move on a incline plane?
The force is up the slope and parralel to it, the load is essentially raised vertically.
What is needed to move a resistance?
a force

What factors effect the amount of force needed to move an object?
The main of force needed tio move an object is the objects mass, f= ma.
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.
