What effect does moving the fulcrum have on a lever?
Moving the fulcrum changes the mechanical advantage of the lever. Placing the fulcrum closer to the load increases the force needed to lift the load but allows for greater distance and speed. Moving it closer to the effort reduces the force needed but decreases the distance and speed.
How can you decrease the amount of force needed to lift a load with a lever?
You can decrease the force needed to lift a load with a lever by increasing the length of the lever arm. By moving the pivot point or fulcrum closer to the load, you can reduce the amount of force required to lift the load.
What kind of class lever is a broom?
A broom is a class 3 lever, where the effort is applied between the load and the fulcrum. This means that when you push on the handle of the broom, the load (dirt, debris) is lifted off the ground.
Does the position of the load for a class-2 lever effect the effort?
Yes, the position of the load on a class-2 lever does affect the amount of effort required. Moving the load closer to the fulcrum reduces the effort needed, while moving it farther away from the fulcrum increases the effort required.
How does changing the fulcrum position of a lever affect the mechanical advantage of the lever?
Changing the fulcrum position of a lever can affect the mechanical advantage by changing the ratio of the lever arms on either side of the fulcrum. Moving the fulcrum closer to the load will increase the mechanical advantage, making it easier to lift the load. Conversely, moving the fulcrum closer to the effort force will decrease the mechanical advantage, requiring more effort to lift the load.
What is the most common use for a lever?
Lever is used in moving a load around a pivot using a force.
What effect does moving the fulcrum have on a lever?
Moving the fulcrum changes the mechanical advantage of the lever. Placing the fulcrum closer to the load increases the force needed to lift the load but allows for greater distance and speed. Moving it closer to the effort reduces the force needed but decreases the distance and speed.

You can decrease the force needed to lift a load with a lever by increasing the length of the lever arm. By moving the pivot point or fulcrum closer to the load, you can reduce the amount of force required to lift the load.
What kind of class lever is a broom?
A broom is a class 3 lever, where the effort is applied between the load and the fulcrum. This means that when you push on the handle of the broom, the load (dirt, debris) is lifted off the ground.
How do you increase the mechanical advantage of a lever?
The mechanical advantage of a lever can be increased by moving the fulcrum towards the load and away from the power end.
Does the position of the load for a class-2 lever effect the effort?
Yes, the position of the load on a class-2 lever does affect the amount of effort required. Moving the load closer to the fulcrum reduces the effort needed, while moving it farther away from the fulcrum increases the effort required.

Changing the fulcrum position of a lever can affect the mechanical advantage by changing the ratio of the lever arms on either side of the fulcrum. Moving the fulcrum closer to the load will increase the mechanical advantage, making it easier to lift the load. Conversely, moving the fulcrum closer to the effort force will decrease the mechanical advantage, requiring more effort to lift the load.
How is a broom a lever?
A broom can be considered a lever because the handle acts as the effort arm, while the head of the broom serves as the load. By applying force to the handle, you can lift and move the load (dirt or debris) using the lever principle of increasing force over a shorter distance.
What type of lever does not increase force but does increase the speed or distance a load travels?
A third-class lever does not increase force but does increase the speed or distance a load travels. In a third-class lever, the effort is between the load and the fulcrum, which results in the load moving a greater distance or speed when the effort is applied.
Is a broom an example of a second class lever?
Yes, a broom is an example of a second-class lever. In a second-class lever, the load is located between the fulcrum and the effort. When you push down on the handle of a broom to sweep, the load (dirt and debris) is located in between the fulcrum (floor) and the effort (your hand on the handle).
What are the 3 parts of a lever?
A Lever comprises of three components:Fulcrum or Pivot - the point about which the lever rotatesLoad or Resistance - the object that requires movingEffort - the force applied by the user of the lever system
What is the definition of a load of a lever?
Load = the force of the weight of the lever fulcrum = the point of which the lever rests effort = the force you apply to the lever
