True
single fixed pulley, single movable pulley and single fixed and movable pulley. :-)
Yes an elevator is a movable pulley!
Fixed if it weighed as less than you, but a movable pulley wouldn't be helpful here. You'd be best with a pulley with multiple supporting ropes.
Single Pulley
True
With the string from the movable pulley
single fixed pulley, single movable pulley and single fixed and movable pulley. :-)
The difference between a fixed pulley and a movable pulley is, the wheel of a fixed pulley does not move because the wheel is attached to a wall, ceiling, or other object. Unlike a fixed pulley, a movable pulley's wheel does move. The wheel on a movable pulley is not attached to a wall or other object. A fixed pulley changes work by changing the direction of a force. A movable pulley changes work by reducing the input force needed to lift heavy objects. A movable pulley changes the direction of the input force and reduced it. A movable pulley also increases the output force.

fixed and movable pulleys can be combined.

Fixed pulley, Movable pulley, block and tackle
When a fixed and movable pulley are used together, the fixed pulley is attached to a stationary object while the movable pulley is attached to the load being lifted. The combination of these pulleys allows for a mechanical advantage, making it easier to lift heavy objects by requiring less force.
The two kinds of pulleys are fixed pulleys and movable pulleys. Fixed pulleys are stationary and change the direction of the force applied, while movable pulleys have a free end that moves and both change the direction of the force and provide a mechanical advantage.
