What question does the text ask about a machine's work?
How fast is the machine?
How much work is it doing for you?
How expensive is the machine?
How heavy is the machine?
What is mechanical advantage?
The amount by which a machine can multiply the force.
The speed at which a machine operates.
The weight a machine can lift.
The size of a machine.
What is the output force in the context of mechanical advantage?
The force the machine applies.
The force you apply.
The speed of the machine.
The weight of the machine.
What does mechanical advantage compare?
Size of the load compared to the effort force.
Speed of the machine compared to its size.
Energy used compared to the time taken.
Weight of the machine compared to its height.

What is the relationship between effort force and load force in a lever?
Effort force is always greater
Load force is always greater
Effort force can be less than load force
They are always equal
What is the purpose of using a lever in the diagram?
To reduce the effort needed
To increase the distance
To change the direction of force
To increase speed
Which of the following statements is true about first-class levers?
The fulcrum is between the effort and the load
The load is between the effort and the fulcrum
The effort is between the load and the fulcrum
The fulcrum is at the end of the lever
Which of the following best describes a first-class lever?
A lever with the fulcrum between the effort and the load
A lever with the load between the effort and the fulcrum
A lever with the effort between the load and the fulcrum
A lever with no fulcrum
What role does the fulcrum play in a lever system?
It increases the load force.
It acts as the pivot point.
It decreases the effort force.
It is where the load is applied.
In the context of levers, what does the term 'effort force' refer to?
The force applied by the load
The force applied by the user
The force at the fulcrum
The force that resists motion
Which of the following is an example of a lever in everyday life?
A pulley
A seesaw
A wheel
A screw
What is the function of the fulcrum in a lever system?
To apply force
To support the lever
To increase speed
To reduce friction
What type of simple machine is a lever?
Inclined plane
Pulley
Wheel and axle
Lever
Which simple machine would be the MOST efficient for lifting an object 30 meters off the ground?
pulley
screw
wedge
lever
To increase the mechanical advantage of a lever,
make sure the fulcrum is in the middle of the lever
move the fulcrum closer to the load
move the fulcrum closer to the effort
use a bigger fulcrum
