What is the relationship between the amount of effort needed to lift the load and the distance of load from the fulcrum?
confusing
What is needed to change the direction of a moving mass?
The answer is force because Force is needed to change the direction of a moving mass.
Which type of machine changes the direction or amount of force needed to do work?
simple machines like pulley, liver and fulcrum.
On a lever how can you reduce the amount of effort needed to lift a heavy object?
by adding more weight to the other side
What two parts are needed to make a lever?
a fulcrum is the part which balences it and the bar, put it on top of the fulcrum Force & Weight are the two parts needed to make a lever.

Jim was clearing trash from his yard so that the construction crew could begin his pool There was one large rock that needed to be moved Why would it be easier for Jim if he used a lever and fulcrum?
The lever and fulcrum decrease the amount of force needed to move the rock
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.

Is it true or false that as the position of the fulcrum changes the amount of force needed to move a box remains the same?
The force at the box would remain the same is true.
Does inertia change with speed?
Inertia is a measurement of the amount of energy needed either to start the object moving, or to slow down or stop its movement. This depends upon the mass (weight) of the object, but more particularly its change of speed. The greater the mass (weight) of the object the greater the amount of energy needed to move it and stop it.
Is net force needed to change the speed or direction of moving matter?
Yes, that's a firm. Net force is needed in order to change the speed or direction of moving matter. Uh huh.
What happens when the fulcrum is further from the load?
The closer the load is to the fulcrum the greater the mechanical advantage. The closer to the fulcrum, the less the load moves when the lever is used.
