Why do pulleys pull stuff?
Pulleys can lift objects by changing the direction of the force needed to move the load. They distribute the force required to lift an object over multiple ropes or cables, making it easier to lift heavy items.
Can a pulley move a load side ways and upwards?
Yes, a pulley can move a load both sideways and upwards with the use of multiple pulleys and appropriate rigging configurations. By adjusting the angle of the pulleys and the direction of the force applied, it is possible to move a load in various directions using a pulley system.
What is the same between pulleys and gears?
Pulleys and gears are both mechanical devices that transmit motion and force. They are used to change the direction or speed of motion within a system. Both pulleys and gears rely on the principle of rotation to transfer energy.
Describe the vibration of the colored ribbon. How does it move as waves pass by Does it move in the same direction as the wave?
The colored ribbon vibrates back and forth perpendicular to the direction of the wave as the waves pass by. It does not move in the same direction as the wave; rather, its movement is perpendicular to the wave's direction.
What happens if you pull two pulleys with the same diameter?
If you pull two pulleys with the same diameter, the mechanical advantage is the same as if you were pulling a single pulley of that size. The force required to move the load will be divided between the two pulleys, making it easier to lift the load. It also increases the overall stability and equalizes the load distribution.
Can you move the direction of two pulleys at once?
Maybe, depends on if you have the right force.

Where do wormholes move?
Same direction as the worms.
How can pulleys change direction of the force?
yes

change the direction of force
Why does a seaweed not move in the same direction as waves?
Seaweed will move in the direction of the sea current. It's not able to move on its own, but can develop moving skills to get around.
