they have become more complicated and with better materials.
also the are in almost all the things we use
No, the speed of light has remained constant over time according to current scientific understanding.
A pulley changes speed by dividing the distance that needs to be moved by the force applied. When a smaller pulley is used, the speed increases because the force is concentrated over a smaller distance. Conversely, a larger pulley decreases speed by spreading the force over a larger distance.
Pulley.
A changing the direction of force is generally achieved using a fixed pulley or a movable pulley, depending on the specific setup. Both types can redirect the force being applied to a different direction without changing the amount of force.
A pulley overcomes static friction, which is the friction between the surface of the pulley and the rope or belt moving over it. This allows the pulley to rotate smoothly and lift objects with less force required.
THey are a pulley.
