You don't say which speed, but all change over time.
Acceleration is the change in velocity ("speed") over time.
The symbol for an average speed is a bold v with a line over the top of it. This is the quantity of change in position over change in time.
Speed --- actually, if your question is 'position' over time, there is no answer since position is a vector quantity. And position divided by time will still yield a vector quantity-- velocity. If the question asks for change in distance over time, then the answer is speed. --gh ---
Change in position over time is velocity ("speed").
You don't say which speed, but all change over time.
No, acceleration is the change in speed over time.
As long as direction doesn't change, speed over time is called acceleration.
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-
Calculation for speed
Acceleration is the change in velocity ("speed") over time.
Speed is equal to the change in distance over the change in time, or V = D/T where V is speed, D is distance and T is time.
The symbol for an average speed is a bold v with a line over the top of it. This is the quantity of change in position over change in time.
speed.
A speed graph measures the distance devided over time. Acceleration graph measures the change in speed over time.

Changes in position over time is motion, and the rate of change may be velocity or speed.
