m/s
Acceleration is typically measured in units of meters per second squared (m/s^2).
Objects moving at constant speed in a straight line are said to be in equilibrium. That is there is no force acting on them. If a force was acting there would be aceleration and the velocity would change.
It is rather subtle. In general yes, if there is no air resistance (or any comparable force) all objects will fall down at the same speed. However this is only strictly true if the masses of the objects are small compared to that of the Earth. This is because we generally attach our coordinate system to the Earth, so if the Earth moves upwards we do not measure it, instead appearing to us as if the object fell down quicker. This is just a consequence of a badly chosen reference frame of course. As an example one would not expect a tea cup to fall down at the same speed as the Moon, because the Moon would actually also pull the Earth towards it. Again if we would properly attach our coordinate system to some place that will remain at rest all objects fall with the same speed.
Without inertia, objects would not resist changes in their motion. This means that any force applied to an object would instantly change its speed or direction, making it impossible to move or control objects effectively. The concept of momentum would not exist, leading to chaotic and unpredictable movements of objects.
They would be traveling at the same speed. Two objects moving with the same velocity must be moving in the same direction and at the same speed. The reason for this is because velocity is speed in a specified direction. Another way to say that is to say that velocity is speed with a direction vector. It is a physical quantity with magnitude and direction. Two objects moving with the same speed could be moving toward a head-on collision. Or they could be moving along convergent, divergent or skewed paths. Not so with two objects that have identical velocities. They are moving on the same or on parallel courses, and they are moving at the same speed.

I'm uncertain about what you are seeking here. The change in an objects speed divided by the time required to change the speed would be the average acceleration.
To use a 10-speed cassette on an 8-speed hub, you would need to use a spacer behind the cassette to fill the extra space. This will allow the 10-speed cassette to fit properly on the 8-speed hub. Make sure to adjust the indexing of the gears properly to ensure smooth shifting.
v = d/t would be Speed is Distance / Time(more properly for physics)Velocity is Displacement / Time
If they have the same engine, it would bolt up. But if it is a 4 speed, the electrical plugs are different, so it would not work properly.If they have the same engine, it would bolt up. But if it is a 4 speed, the electrical plugs are different, so it would not work properly.
I have ran into aftermarket wheel bearings that the speed sensors do not read properly.I have ran into aftermarket wheel bearings that the speed sensors do not read properly.
Try it. That's what's known as an experiment.
To use an 11-speed cassette on an 8-speed hub, you would need to use a spacer to fill the extra space on the hub. This will allow the cassette to fit properly and function with the 8-speed hub.
