basically projectile motion is the best example in our earth of 2-d kinematics....uses of projectile motionProjectile motion is applied in most of our daily activities like playing cricket, playing badmintion. Jumping of animals is also an example of projectile motion. Throwing of missile from cannon too a good use of projectile motion.
Acceleration is the change in an ogjects speed or a change in an objects direction of motion or both of these. If instead of speed you use the word velocity , which is both an object's speed and its direction of motion, then you could say "acceleration is the change in an objects velocity" and that would cover all the possibilities in one statement.
we use pulleys and gears in our daily lives because it would make it easier for people to do our work.We would not have to work so hard.We use pulleys to lift heavy objects.We use gears to build stuff. That's why we see gears in some of our objects.(If you look at a egg beater,you will see gears in a egg beater).
Both generator and motor are energy converters. Subject to losses, both convert one form of energy into another. All motors and generators use a form of motion on one side of their energy conversion process (typically, but not necessarily, rotary motion). For example, a petrol engine is a motor that converts combustible fuel into rotary motion, an electric generator converts (typically rotary) motion into electric energy. Complimentary motor/generator pairs are only possible among certain forms of energy. For example, an electric motor can be connected to a generator, thus converting electric energy into rotary motion, and converting rotary motion back into electric energy. Other complimentary motor/generator pairs are only possible by indirection. For example, a wind turbine converts wind energy into rotation, which can be converted into electric energy with an (electric) generator. This generator's output can then supply an electric motor, which converts it into rotary motion, which in turn might drive a fan blade, thus converting rotary motion into wind energy. Not all energy forms support complimentary motor/generator pairs. Combustible fuels such as petrol, for example, can be converted into rotary motion which a combustion engine. However, a generator capable of converting rotary motion into combustible fuel has yet to be invented.

Yes, if you apply it to every individual particle, or use integration.However, for practical calculations, it is often convenient to consider rotary motion separately. There is a rotational equivalent of Newton's Second Law (force = mass x acceleration), where you replace the force with a torque, the mass with the moment of inertia, and the acceleration with angular acceleration.The moment of inertia for objects of different forms are calculated through integration.Yes, if you apply it to every individual particle, or use integration.However, for practical calculations, it is often convenient to consider rotary motion separately.

Objects with large proper motion tend to be closer than objects with small proper motion. /\

Use the force young pad-wan! An external force is required to start an object in motion from rest.
Not necessarily. Some fans use belts on pulleys to transfer the rotary motion of the motor to the fan blade, while others use gears, and some are direct drive.
"Think of a simple single cylinder engine....crankshaft goes round & round,piston goes up & down,connecting rod keeps the two tied together...wa la!" This type of linear motion is known as reciprocating motion, where the linear motion is a repetitive up and down, or back and forth action. The linear motion velocity of a wheel and crank system is not uniform and conforms to a sinusodial curve, i.e. it is slowest at the 0º and 180º positions and fastest at the 90º position. To get uniform linear motion from uniform rotary motion, you can use a threaded shaft and thread follower arrangement, or a rack and pinion. btw, it's "voila!".
No, rotary engines went out of use in aircraft in WW1.
