When you change the mass of a load, it creates less friction because there is less for gravity to act on.

What is the force that tends to keep a load from moving?

Friction is the force that tends to keep a load from moving. It acts in the opposite direction to the force applied to move the load, making it harder to overcome.


How does increased friction affect the actual mechanical advantage of a machine?

Increased friction reduces the actual mechanical advantage of a machine because more of the input force is used to overcome friction rather than move the load. This results in less of the input force being effectively transferred to the load, decreasing the overall efficiency of the machine.


Whats the force needed to move a load?

The force needed to move a load depends on factors such as the weight of the load, the surface it is being moved on, and any friction present. To calculate the force required, you can use the formula Force = mass x acceleration, where mass is the weight of the load and acceleration is the rate at which the load is being moved.


What are 2 variables that are involved with friction?

Two variables involved with friction are the nature of the surfaces in contact and the force pressing the surfaces together. The roughness or smoothness of the surfaces, as well as the weight or load applied on them, can affect the amount of friction generated.


How did the pulley affect the amount of force needed?

A pulley reduces the amount of force needed to lift an object by distributing the load over multiple ropes and wheels. It allows you to lift heavier objects with less effort by changing the direction of the force required to lift the load.

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.


How does an increase in the load force affect the efficiency of a pulley system?

Increasing the load force in a pulley system can decrease its efficiency due to increased friction and mechanical losses. This leads to a higher amount of energy being required to lift the load, reducing the overall efficiency of the system.


How would the amount of force that is needed to put the load up the inclined plane be reduced?

Reduce the friction


What is the relationship between input force output force and load force?

The input force is the force applied to a system, while the output force is the force produced by the system. The load force is the force exerted by the load on the system. In an ideal situation, the output force is equal to the input force, but in reality, due to factors like friction and mechanical efficiency, the output force may be less than the input force. The load force is the force that the system must overcome to perform work.


What are the units that friction is measured in?

The coefficient of friction is dimensionless; it has no units.


How does changing the distance from the fulcrum to load affect the effort needed to lift the load?

Increasing the distance from the fulcrum to the load will increase the effort needed to lift the load. This is because when the load is farther from the fulcrum, a greater force is required to overcome the increased resistance due to the longer lever arm. Conversely, decreasing the distance from the fulcrum to the load will require less effort to lift the load.


Does it always take the same amount of force to lift load?

No, the amount of force required to lift a load can vary depending on factors such as the weight of the load, the distance it needs to be lifted, and the presence of any friction or resistance. A heavier load or a greater distance will typically require more force to lift.
