simply put the acceleration is the slope of the speed vs time graph
Theory Part
think of it this way. the unit for speed is meters per second or m/s
the unit for acceleration is meters per second per second or m/s2
so essentially if speed is the change in position per change in time, acceleration is the change in speed per change in time.
Practical Part
now for the actual answer. look at the slope of your speed vs time graph at any time. that slope is the acceleration at that time. If you find the slope between two points on your graph, that gives you the average acceleration over that interval of time.

∙ 13y agoVelocity (speed) is the derivative of position. If you haven't taken calculus yet, derivative is simply slope. To find the speed of your object, pick out two points on your graph and find the slope between them.
To get the concept behind that, think about the units of speed: distance divided by time, like miles/hr. When you calculate slope, you take (distance unit - distance unit) / (time unit - time unit) and finally reach distance unit / time unit.

∙ 11y agoAcceleration is the derivative of velocity with respect to time.
What that means is, if you have a graph with time on x axis and velocity on the y axis, the slope of the line at a point in time is the acceleration at that same point in time.
if your velocity is a linear function of time (a straight line -- not curvy) you can find the acceleration in this way.
pick a time value, we'll call it t1.
pick another time value, we'll call it t2.
find the velocity associated with t1, we'll call it v1 v1=v(t1)
find the velocity associated with t2, we'll call it v2 v2=v(t2)
acceleration = (v2-v1)/(t2-t1)
and your units will be your units of velocity divided by the units of time. For example, if you're measuring velocity in miles per hour (mph) and time in seconds, your units will be miles/(hours*seconds). If you're using meters per second and seconds, it will be meters/(seconds^2).
Note that velocity is a vector quantity (it has a direction associated with it) and so is acceleration. Having non-zero acceleration means there will be a change in velocity, however, it does NOT NECESSARILY mean there will be a change in SPEED (which is the magnitude of velocity).

Note that the value this slope is the maximum speed, since the slope at any point on distance time graph is velocity

In an acceleration graph showing speed versus time a straight line shows the acceleration is?
A graph that shows speed versus time is not an acceleration graph.The slope of the graph at any point is the acceleration at that time.A straight line shows that the acceleration is constant.
How would one determine Acceleration from a V-t Graph?
The slope of graph of V->t gives the acceleration
Is The slope on a position-time graph is representative of the acceleration of the object?
No. Slope of position/time graph is speed, or magnitude of velocity.Slope of speed/time graph is magnitude of acceleration.
What is the gradient of acceleration time graph?
There is not a word for it but it it the rate of change of acceleration.
What happens to acceleration when speed decreases on a speed time graph?
Acceleration is negative.
What part of the graph represents uniform positive and negative acceleration Calculate this acceleration.?
The answer depends on whether the graph is that of speed v time or distance v time.
How can you find the retardation of a curve in a speed time graph?
Calculate the gradient of the curve which will give the acceleration. Change the sign of the answer to convert acceleration into retardation.
How do you find acceleration of a speed time graph?
Acceleration=change in y graph/change in x graph
What does acceleration look like as a graph?
The answer depends on what is plotted on the graph and what is happening with the acceleration then.
What represents acceleration on a graph?
The answer depends on the variables in the graph! In a graph of age against mass there is nothing that represents acceleration.
How do you calculate area under the acceleration time graph?
The mathematical technique used to calculate the area under a graph is integral calculus. This is a complex subject which I am not going to attempt to explain in detail- it normally takes years of study.
How would a graph of negative and positive acceleration differ?
This depends on what the graph represents. If it is a graph of velocity on the vertical and time on the horizontal, then if acceleration is at a constant rate, the graph will be a straight line with positive slope (pointing 'up'). If acceleration stops, then the graph will be a horizontal line (zero acceleration or deceleration). If it is deceleration (negative acceleration), then the graph will have negative slope (pointing down).
What is accelerated motion?
►►The rate of change of velocity per unit of time is defined as accleration►2.If we write the definition for acceleration in mathematical terms:Final Velocity - Initial VelocityTime
How is a graph showing speed different from a graph showing acceleration?
Acceleration is how fast you get up to speed.
How do you make a velocity vs time graph from an acceleration vs time graph?
Your acceleration vs. Time graph is the slope of your velocity vs. time graph
In an acceleration graph showing speed versus time a straight line shows the acceleration is?
A graph that shows speed versus time is not an acceleration graph.The slope of the graph at any point is the acceleration at that time.A straight line shows that the acceleration is constant.
How do you find acceleration using mass and velocity?
Acceleration is change in velocity per unit time(derivative of velocity with respect to time). If you have a graph or chart of velocity values vs time, then you can calculate (change in velocity) / (change in time). This is the slope of the graph at a specific point in time.Mass, along with acceleration determines force.
