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.
force's can change the speed, shape, size and direction of an object.
A machine saves you force, changes distance, and changes direction. Those are the three ways in science that why machines are useful.
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.
speed and direction
Velocity and force are similar in that they are both vector quantities, meaning they have both magnitude and direction. Additionally, both velocity and force are related to the motion of an object, with velocity representing the speed and direction of an object's movement, and force representing the push or pull acting on an object to cause it to move or change its motion.
