You get greater mechanical advantage the closer the fulcrum is to the resistance (load).

When is mechanical advantage increased by a first class lever?
The mechanical advantage is when the fulcrum is closer to the effort and creates a advantage
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
Is acceleration the rate of change of the rate of change of position?
no its speed that definds the rate change of position
What is an object's overall change in position called?
Displacement is the overall change in position
Which class of lever does not multiply input force?
The first class lever (force, fulcrum, load) doesn't change the force if the lever is symetrical. Note that if it is assymetrical, the force will change.

What is the major of advantage of pushpull steering from the low hand position?
It makes it more easy to change gear
Where are the load effort and fulcrum located on a second class lever?
No, the function of the fulcrum remains the same The only change would be the ratio of force to load The closer the fulcrum is the the load, the less force required to lift it The farther away the fulcrum is from the load, the more force required to lift it
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.
What advantage is there in having a wheelchair that allows people to change position?
Changes of position relieve pressure and can help lessen the development of skin irritation. Changing position can also help some people breathe more easily.
What can generally be defined as a change in position?
Movement is a change in position
What is preposition as to economics?
The likely reference is the word pre-position, not preposition (a part of speech). To pre-position is to make advance preparations, in anticipation of an occurrence or event. For example, a firm may "pre-position" itself (its finances and obligations) to take advantage of a change in economic conditions.
What is the change in objects position?
The change in an objects position is called motion.
Motion is a change in?
Motion is the change in an object's position.
Continuous change in position is called?
Motion is continues change in position...
Is acceleration the rate of change of the rate of change of position?
no its speed that definds the rate change of position
