Speed is the distance moved divided by time - 10 mph.
Velocity is the distance moved divided by time, and the direction traveled - 10 mph @ 3 degrees clockwise from N.
A ferris wheel gondola is constantly changing its direction of travel, it has to to stay attached to the wheel. The gondola itself doesn't move in a straight line, so even if the car moves at a constant speed of 0.5 meters per second, it's velocity is never the same from one instant to the next.
Acceleration, in an engineering/physics sense, is not an increase in speed, but a change in velocity. Since the gondola is constantly changing velocity (because it is changing direction), it is constantly accelerating.

To accelerate an object is to change its velocity, which is accomplished by altering either its speed or direction (as in the case of uniform circular motion) in relation to time.
On the ferris wheel you are continuously changing direction so you are always accelerating.

Assuming there's gravity, in order to move at a constant speed in a circular fashion, acceleration will change direction ( ex: you move up on one side and half a circle later you're moving down ) and its magnitude ( ex: you need less force to move down since there's gravity, and you need more force to move up; mass is constant, so acceleration's magnitude will change ). I hope I'm explaining well enough.

you are changing horizontal and vertical velocities constantly, at the high and low point of the ferris wheel your vertical velocity is zero, but it accelerates to a maximum half way up, then back to zero again
(the angular velocity is constant, therefore no angular acceleration)

"to discover the acceleration of an merchandise transferring in a immediately line, you need to calculate the substitute in distance throughout the time of each and each and every unit of time." acceleration is the speed of substitute of speed in line with unit time. measuring the gap for unit time gained't furnish you with acceleration. fake "A ferris wheel wheel turning at a consistent % of 5 m/s isn't accelerating." The tangent at each and each and every aspect of the action supplies the speed. For it to no longer be accelerating the route of the tangent would continually ought to point interior of an similar route. no longer the case with the Ferris wheel. At each and each and every aspect in time, the tangent factors in a diverse route so as that the route variations with time. speed is a vector volume that signifies that the speed variations with time and hence it is accelerating. end note:fake "An plane is flying west at 2 hundred km/h. 2 hours later, it is flying west at three hundred km/h. Its undemanding acceleration is one hundred km/h^2" fake: Acceleration= (V-U)/t = (three hundred-one hundred)/2 =/= 100km/h^2

Your tangengtial speed is what is constant, i.e. your angular acceleration is zero. Velocity is a vector quantity, speed is not.

because you are changing direction in a circular motion
