There are two ways to interpret your question. If you want to know the units of measurement used to measure acceleration, that would normally be meters per second per second, in a scientific context, although in other contexts it could be miles per hour per second, or various other units. If you want to know how the measurement is actually made, there are various ways, but a convenient method would be to take a motion picture of a moving object, which allows you to measure its position at any given time; you can then graph location vs. time, and the shape of the graph will suggest an appropriate equation that would describe the acceleration. Then, additional measurements can be used to either confirm or reject the proposed equation. There is a lot of math involved; acceleration is analysed with differential calculus. But it does start just by measuring the position of an object at various different times.
finite and infinite graph.
Velocity and Time
It is velocity and distance. ----
velocity and distance.
The slope of the line of a speed-versus-time graph will give you acceleration. Remember that acceleration may be positive or negative, and in some cases, acceleration may be positive when speed remains the same.1 If the speed-time curve is linear or piecewise linear2, acceleration is, as stated above, merely the slope of the line segment. If, however, the graph is a smooth curve, then changing acceleration is represented. In other words, the rate of change of velocity -- delta-V over delta-T -- is not a constant. In that case, the slope of the line segment tangent to the curve at any given point is the acceleration at that point. Note 1: There is a discussion comment on this point.Note 2: See the web link for an example of a graph that is piecewise linear.
For comparing the acceleration of automobiles, a velocity vs. time graph is most efficient, where time is the x value, and velocity the y value. The greater the acceleration of the automobile, the steeper the slope of its respective plotted line.
Velocity is defined by physicists as both speed and direction, that is to say, if you are moving at 30 feet per second in a northerly direction, that is a velocity. Acceleration means a change in velocity. Physicists consider speeding up, slowing down, or changing direction all to be forms of acceleration; in more everyday usage, acceleration us used to mean speeding up and deceleration means slowing down. So, if your speed increases from 30 feet per second to 40 feet per second, that is acceleration.
You can't. However, you can find the change in speed between two points in time by finding the area under the acceleration-time graph.
Force and mass. Acceleration is force per unit of mass (a=f/m).
Derivitives of a velocity : time graph are acceleration and distance travelled. Acceleration = velocity change / time ( slope of the graph ) a = (v - u) / t Distance travelled = average velocity between two time values * time (area under the graph) s = ((v - u) / 2) * t
The slope of height vs. time squared graph equals (g) - acceleration due to gravity divided by two. In symbols m = g/2, where m is the slope and g is the acceleration due to gravity.
Rise is the vertical distance between the two points on the graph. This is measured using the Y axis.
