How do you find the speed of an object?
The speed of an object at a time is found by determining its rate of change of distance. If the speed is constant, it can be determined by the ratio of distance to time taken.
Is motion the change in speed?
no motion is the movement itself, the change in position of an object with respect to time. rate of change of speed is acceleration. change in speed is just change in speed.
What does speed describe?
The change in distance with respect to time of an object.
What can you say about the motion of an object if its speed-time graph is a straight line parallel to the time axis?
If the graph if speed vs. time is a straight line parallel to the time axis, then the speed is not changing.Acceleration is the slope of the line on such a graph. Slope is (speed change) divided by (time for the change).Since the speed doesn't change over any period of time, the slope of the line is zero.The object's speed is constant. Its acceleration is zero.
How are speed and changes in an object's position related?
Change in position over time is velocity ("speed").
What is the difference of accelaration and decelaration?
Acceleration is an increase in change in speed over time of an object, and deceleration is a decrease in the change in speed over time of an object. -aerol-
What is the relationship of the object's speed to its velocity?
Speed is the rate of change of distance with time. Velocity is the rate of change of displacement with time.

When does the speed of an object change?
An object's speed changes whenever the rate of change between the distance the object travels and the time it takes to travel that distance changes. Do not confuse speed with velocity; speed is scalar, and velocity is vector. Velocity can change when speed remains constant.

Which term defined as the change in an object positions over time without including direction?
The rate of change of an object's position over time is the object's speed.

When is a time where speed does not change but the object is still accelerating?
Acceleration is the time rate of change of velocity. Velocity is a vector. It has a magnitude ( speed ) and a directio. If either the speed or the direction of motion changes the object is accelerating. Example; an object moving in a circle at constant speed is accelerating because its direction is continually changing.
What does straight line on a distance time graph tell you about the speed of an object?
It tells you that the speed of the object is not changing. The speed is represented by the slope in a distance vs. time graph, if slope doesn't change, speed doesn't.
