A pulley system may cause the direction of the output force to differ from that of the input force, but is not guaranteed to do so. In a simple example, a double pulley could easily result in input and output forces in parallel.
yes, cause you have put less input force since the pulley doesn't move. So it takes a slim amount of less energy
Yes.
retrograde motion
retrograde rotation
Venus rotates on its axis the opposite direction that it orbits, the opposite of most planets in the solar system. (Note that Uranus rotates on its side.)
This is called retrograde rotation. Within our solar system, the planets of Venus and Uranus have retrograde rotation.

False, Unless it is a twisted pulley system.
A Pulley is basically a kind of lever that can be used to change the direction of a force. Properly used, a pulley or system of pulleys can multiply forces
A pulley system that has multiple pulleys in line with each one having its output drive the next will increase the force. This would be called a tackle pulley.

Change the direction of force and multiply the force.
A single pulley system is used to change direction of the pulling force line.
Depends what the input force is and the mechanical advantage of the pulley system If effort force (input force) is 20 pounds in a 6 pulley system (3 fixed,3 movable) then load force (output force) is 120 pounds As 6 times 20 equals 120 pounds
The load will move upwards.
1/4 the output force.
If the pulley is frictionless the angle does not matter, the tension in the rope will be the same on both sides of the pulley. If there is friction in the pulley however then you want to reduce the friction as much as possible. You do that by creating as large an angle between the two ropes as possible.
The idler pulley is a unit connected to the engine via a brace or bracket. This part merely routs the belt in a certain direction and, if bad, will cause a failure of the total serpentine system or cause belt wear as with any bad pulley in the system.
A double pulley system is simple. Instead of one wheel like the single pulley system has, the double pulley system has two wheels and carries more heavier loads than the single pulley system can hold.
