When a neutron star is first formed (Pulsars are just neutron stars - see related question) it retains most of its angular momentum.
As it now only has a tiny fraction of its "parent's" radius, a neutron star is formed with a very high rotation speed.
It's similar to watching ice skaters spinning with their arms out and then suddenly bringing them to their sides.
it changes direction,it speeds up or slows down
You don't get the friction you need to accelerate on ice. This is why asphalt is used on roads, tyres can grip on it and the friction will create higher speeds.
Yes, synchrotrons use radiofrequency cavities to accelerate charged particles to high speeds by providing a kick of energy each time the particles pass through. This compensates for the increase in the particles' mass due to their high speeds, allowing them to achieve relativistic velocities.
Yes, the presence of salt can accelerate the process of rusting by increasing the conductivity of water, which speeds up the corrosion of metal.
Different internal combustion engines have different rotational speeds.
A pulsar is a neutron star that rotates and sends a beam of electromagnetic radiation. This is known because only a very dense source of such radiation would be capable of rotating that quickly without disintegrating.
All young neutron stars in reality are "pulsars". However, for a neutron star to be termed a pulsar, it's magnetic axis has to point towards Earth. (So we can see the pulse, even though all young neutron stars have a pulse, they cannot be observed from Earth.)
is commonly performed using a handheld engine that can reach rotational speeds of 18,000-35,000 rpm. Rapid planing of the skin is achieved through the combination of this rotational speed, the abrading attachment, and pressure applied by the operator

Gear ratio is the ratio of the rotational speeds of the first and last gears. It reflects the change in mechanical advantage which results from the gears.
