Objects moving at a constant speed in a straight are said to be in?
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.
Will objects fall at the same speed if there is no air?
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.
Acceleration is a change in speed or?
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.
Does water resistance speed up moving objects?
No, it would slow objects down. Resistance implies that the water is acting against the object's motion, slowing it down.
Air molecules speed up the movement of objects in motion?
The friction (with the air molecules) would slow it down.

If To graph an objects speed what two values would be on the graph?
x and y
What are differences in speed called?
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.

What do each of the variables in speed equation stand for?
v = d/t would be Speed is Distance / Time(more properly for physics)Velocity is Displacement / Time
Will a 93 Dodge Caravan transmission fit in a 97 Dodge Caravan?
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.
What would stop a speed sensor from working on a newly replaced front wheel bearing of a dodge 1500 4x4?
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.
How would you test the hypothesis that objects fall at the same speed regardless of their mass?
Try it. That's what's known as an experiment.
How fast is something is moving?
How fast something moves is the speed. Airplanes are one of fastest moving objects in the world, and cheetahs are one of the fastest animals.
