pulleys, levers, pendulums
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.
1. Take a small input and you get a large force.
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.
A machine saves you force, changes distance, and changes direction. Those are the three ways in science that why machines are useful.
force's can change the speed, shape, size and direction of an object.
Force can change the speed, direction, or shape of an object's motion. It can cause an object to speed up, slow down, or change its path of motion. Force can also cause an object to deform or break depending on its magnitude and direction.
A force can change the motion of a body by causing it to speed up, slow down, change direction, or deform. These changes occur due to the interaction between the force applied and the mass and geometry of the object.
If a force is exerted on an object, it will accelerate in inverse proportion to its mass in the direction of the force. For example, if two objects of different mass are subjected to the same force, the less massive object will accelerate more.
1) speed 2) direction 3) shape
The object can be moved in the direction of the force, changing its position. The object can be stretched or compressed, changing its shape or size. The object can be rotated, causing it to change its orientation.
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.
