Velocity is defined as distance traveled (directed distance, to be precise), divided by time. Informally, it tells you how fast something goes.
Velocity can be found either by following formulas, v2 = u2 - 2as or v = distance by time,etc
"Constant velocity" simply means that the velocity doesn't change over time.
There is average velocity, and there is instantaneous velocity. I don't think "overall velocity" is a concept generally used in physics; please clarify what you mean.
Fundamentally, you measure distance and time. If instead you have some assorted facts such as initial velocity, final velocity, time, acceleration and so on then you would use the SUVAT equations, which you can look up in wikipedia.
In physics, Velocity = Distance/Time. Therefore, Time= Distance/Velocity. Insert the Velocity and you get Time= Distance/100. However you'd have to convert either the distance to miles or velocity to feet. 1 mile= 5,280 feet
You can't. All you can tell from time and distance is the average speed during that time.
The slope of a velocity-time graph that shows uniform acceleration is the actual acceleration. Instantaneous velocity is the velocity of a body at a particular moment in time.
Acceleration is a change in velocity over a period of time.
The general technique is: Select a helpful equation from among the plethora to be found in your Physics text.Here comes one now:Final speed = (initial speed) + [ (acceleration) x (time) ]
It is Distance travelled by body per unit of time
distance/velocity = time
With that information, you can find the average magnitudeof the accelerationduring that period of time. You can't tell what either the magnitude or directionwere at any time during, only the average magnitude for the whole interval.
