1. Take a small input and you get a large force.
A machine can change a force by using mechanisms like levers, pulleys, gears, or hydraulics to amplify or redirect the force being applied. These mechanisms can help increase the force applied by the machine, change the direction of the force, or transfer the force over a distance.
Gears can alter motion by changing the speed of rotation and changing the direction of rotation.
A force can be described by its magnitude, which is the strength of the force, and its direction, which is the path along which the force acts.
Two ways to measure force are using a spring balance, which relies on Hooke's Law to measure the extension of a spring when a force is applied, and using a force plate, which measures the force exerted on it by an object standing or jumping on it.
To reduce the gravitational force in a room, you would need to change the mass of the objects in the room or reduce the distance between the objects and the center of the Earth. Since we cannot alter gravity itself, practical ways to reduce the effect of gravity include using lighter materials in construction or reducing the height of the room.
To calculate the mechanical advantage of a compound machine, you need to know the input force applied to the machine and the output force obtained from the machine. Additionally, you will need to understand how the individual simple machines within the compound machine are connected or arranged to determine the total mechanical advantage.
A simple machine can change your input force in three primary ways: by multiplying the force, allowing you to apply less effort to move a heavier load; by changing the direction of the force, enabling you to lift or move an object more conveniently; and by increasing the distance over which the force is applied, allowing for a smaller force to achieve the same work over a longer distance. These principles are exemplified in machines like levers, pulleys, and inclined planes.
pulleys, levers, pendulums
output force is al ways less than input force

i think it means to push or pull
I.reduce the amount of energy needed to perform a task II.change the direction of the input force III.reduce the size of the input force needed to perform a task I and III only
A machine saves you force, changes distance, and changes direction. Those are the three ways in science that why machines are useful.
It's 1. IMA = Distance in / Distance out. A single pulley doesn't do anything toward mechanical advantage, it changes the direction of the force. Not always. A single-axeled pulley (the typical pulley) has an IMA of 1, having one axel. If there was a second axel, then the IMA would = 2, so on and so forth. The easy way to do it is IMA = # of axels.
Simple machines change a force by either multiplying the input force or changing the direction of the force applied. For instance, a lever allows a small input force to lift a heavier load by increasing the distance over which the force is applied. Pulleys can redirect a force, making it easier to lift objects vertically. Additionally, inclined planes reduce the effort needed to lift an object by spreading the work over a longer distance.
machines make work easier by cahnging the amount of force exerted, and changing the distance and derection of the force
Gears can alter motion by changing the speed of rotation and changing the direction of rotation.
