How do speed and position relate to one another?
If one knows the POSITION and SPEED of an object at a given time, one can then predict the position of that object relative to the original POSITION at any time afterwards. Also useful to know would be the DIRECTION in which it was moving - which would enable a more accurate prediction of it's subsequent position; and any rate of ACCELERATION (or its negative, deceleration), i.e. the rate of change of speed, as this would also affect the object's subsequent position.
What is the frame of reference for position speed and acceleration?
The frame of reference with regard to postion, speed and acceleration is just your perspective in measuring speed, position, or acceleration. Say you are watching a horse and a train moving alongside each other in the same direction. If you are standing on still ground, you observe the horse and the train moving at a certain speed relative to you. Let's assume this speed is three meters per second. Now suppose you are on the train looking at the horse, which is still moving at the same speed in the same direction. You will see the horse moving at zero meters per second relative to you, because both you and the horse are moving at the same speed. Even though you are both moving, the horse will still move along side you as if you and the horse are standing perfectly still.

An object's position is defined in relation to the speed of another object true or false?
That is one way to define a position, although it is not the only way. My position, for example, is defined by an address, which tells where I am in relation to a particular street in a particular city. The street and city are not moving with respect to myself (one could argue that they are moving with respect to the sun, but that is irrelevant to the problem of determining my own position). So the speed of that street would be measured as zero. The address, nonetheless, specifies my location on the street, even though at every address on that street, the speed of the street remains zero.
Is the speed of motion position?
Almost. speed is (the rate of) the change in position.
How can you tell if an object is moving when it's motion is too slow to see?
mark its' current position and leave it for a period of time. Then measure and divide for speed.

What kind of motion must an object have in order to predict its position if you only know its average speed?
Velocity
Is dynamics the speed?
No. Dynamics is a branch of physics which deals with the study of bodies moving as a result of forces acting on them.
Can a position time graph have negative slope?
yes, if the speed is negative, that is, moving backward
How speed distance and time of a moving object related to each other?
In the case of constant speed: distance = speed x time For variable speed: speed = ds/dt, where "s" is the object's position.
How can you practice safety when dealing with moving objects?
Monitor, and maintain awareness of, the position, speed, and direction of all moving objects. Maintain and continuously update predictions of the future course of each moving object. Move out of the path of any moving object, i.e. get out of the way, before it reaches your position.
What is the speed limit following a slow moving vehicle?
The speed limit doesn't change - you simply find yourself in a position where you're forced to slow down for them.

When is an object in motion?
When its position changes with respect to a point of reference.
Is speed and velocity are same?
Not quite. Speed only measures how fast an object is moving, while velocity measures change in position relative to time. For example, an object that moves from point A to point B, and then back to it's original position, may move with speed, but since there is no change in position, velocity would be 0.
The position of a moving ant is given by: r = (tsin(t), tcos(t), 1)Find its speed?

What is the difference between speed and velocity-?
Speed is simply how fast something is moving. Velocity is the rate that the object changes position. Imaging taking one step forward and one step back. The speed at which you do this may be 2 miles per hour but the velocity is zero because there is no change in position.
