The size of the force must be greater.
In a machine with a mechanical advantage of 3, the output force is exerted over a shorter distance compared to the distance over which the input force is exerted. The output force is three times greater than the input force but is exerted over a third of the distance traveled by the input force due to the principle of work conservation.
In an ideal machine, the input force will be smaller than the output force when the input force is exerted over a greater distance than the output force. This is because work input and work output must be equal in an ideal machine, and since work = force x distance, a smaller input force over a greater distance will result in a larger output force over a shorter distance to maintain equilibrium.
The formula for work exerted by each simple machine is: Lever: Work = Input force × Input distance = Output force × Output distance Inclined plane: Work = Input force × Input distance = Output force × Output distance Pulley: Work = Input force × Input distance = Output force × Output distance Wheel and axle: Work = Input force × Input radius = Output force × Output radius Wedge: Work = Input force × Input distance = Output force × Output distance Screw: Work = Input force × Input distance = Output force × Output distance
The number of times a machine increases a force exerted on it is called mechanical advantage.
The force exerted by a person on a machine is typically the input force required to operate the machine. This force can vary depending on the type of machine and the task being performed. It is important to consider factors such as friction and mechanical advantage when calculating the force exerted on a machine.

Work, which = Force x Distance (yes there is actually a formula).
Answer: Output force is the force exerted on an object by a simple machine.
input force
In an ideal machine, the input force will be smaller than the output force when the input force is exerted over a greater distance than the output force. This is because work input and work output must be equal in an ideal machine, and since work = force x distance, a smaller input force over a greater distance will result in a larger output force over a shorter distance to maintain equilibrium.

The difference between and input force and an output force is that an output force is force exerted by a machine, and an input force is force exerted on a machine.
