Spur gears give 180 degree drive, and worm gears give 90 degree drive.
Spur Gear is the most efficient
The shape is known as an involute the shape is analogous to unwinding a piece of string from a spool representing the base circle diameter of the gear, imagine your pencil at the end of the string and the string kept tight during unwinding, unwind until line meets OD of gear, then apply blend radius at base circle, then mirror about tooth centre line for full tooth profile.
Planetary gears can be spur or helical gears.
One of the most common types of gears is the Spur Gear. They are most round with teeth along the edging. Spur Gears are used in oscillating sprinklers or fans, windup clocks, washing machines and dyers.
Not certain what you mean but try google / involute curve , then click on the involute curvethe involute curve is the fundemantal shape of (amongst others) a spur gear tooth profile, generated from the gear base circle diameter.

The flow difference in gear compares because it spurs for 5 hours.
Spur gears give 180 degree drive, and worm gears give 90 degree drive.
cane is a big piece and the spur is a small is a piece
its the same
A spur gear.
A helical is a spur gear with an angle along the face to increase the gear contact ratio. The gear teeth are cut at angles http://www.motioncontrolguide.com/learn/faqs/gearboxes-and-gears/helical-gears/what-is-the-difference-between-a-helical-gearbox-and-a-straight-gear-tooth-gearbox/ hope this helps

Reverse gear is spur because it has to slide, sliding mesh gearbox uses spur gears. Because if it was constant mesh gear (helical) it could not slide in and out, therefore it could not go in the opposite direction of rotation.
