rotational acceleration
It has something to do with vectors, but I forget what

Physics, blah. It has something to do with changing direction. I found some pretty good infomation on the website I listed below:
Uniform circular motion can be described as the motion of an object in a circle at a constant speed. As an object moves in a circle, it is constantly changing its direction. Because of this direction change, you can be certain that an object undergoing circular motion is accelerating (even if it is moving at constant speed). And in accord with Newton's second law of motion, an accelerating object must be acted upon by an unbalanced force. This unbalanced force is in the same direction as the direction of the acceleration. For objects in uniform circular motion, the net force and subsequent acceleration is directed inwards. It is often said that circular motion requires an inward (or "centripetal") force.
Good luck!

An acceleration is any substitute in speed OR ANY substitute IN direction. yet a relentless speed calls for that the merchandise is shifting in a at recent line with consistent speed so neither of those components are changing. And on your occasion you're changing your speed via utilising the accelerator so which you at the instant are not shifting at the two consistent speed OR consistent speed. in case you go around a nook you will desire to nonetheless have the comparable speed yet as you at the instant are shifting in a direction then your speed has altered. to supply a greater occasion. you're vacationing North from Seattle to Vancouver at a mushy a hundred km / hr so which you're coming near vancouver at a hundred km/hr Foolishly you ask a physics scholar to examine the map and he turns you east in the direction of spokane. you're nonetheless vacationing on the comparable speed yet how promptly are you coming near vancouver. it is likewise possible to be going far flung from it at possibly 10 km/hr given the instructions I quote. So your speed RELATIVE TO VANCOUVER has altered and you have had an acceleration.

speed is a scalar quantity but velocity is vector quantity. althougth the speed is constant but the velocity is vary since it also consider the direction of the velocity. when there is a change in velocity, it has acceleration, because acceleration is the rate of change in velocity.
for further info ask ur teacher!

constant is not accelerating. accelerating is increasing speed. constant speed would be a continuous speed.

It may be rotating but is it going forward?
