Average acceleration = Change in speed/time
Time = Change in speed/Average acceleration
To calculate acceleration, divide the change in speed by the time during which the acceleration occurs. :)
Acceleration = (change in speed) divided by (time interval)
(Distance covered) and (time to cover the distance) is enough informationto calculate average speed during the time, but not enough to calculateacceleration.
It depends on what the graph is: displacement-time, or speed-time or acceleration-time or something else.
The answer depends on what you want to do: calculate acceleration, journey time?
Acceleration is the time rate of change of speed. Acceleration = speed/time.
If you know the initial speed (u), acceleration (a) and time (t), then the final speed, v = u + at.
Speed = Time x acceleration
speed equals to acceleration into time
Speed and time. As acceleration is the change in speed over time.However, if you do not have a direct reading of speed, you will need to claculate that also, from distance over time.So all the units are:-Distance = MetresTime. = SecondsSpeed = m/sAcceleration = m/s/s or m/s2
The answer depends on whether the graph is that of speed v time or distance v time.
Calculate the gradient of the curve which will give the acceleration. Change the sign of the answer to convert acceleration into retardation.
You can't convert acceleration to speed or vice versa, if that's what you mean, since they are really quite different things. Acceleration is defined as the rate of change of velocity (dv/dt); therefore it has units of speed / time, or equivalently, distance / time squared.
Acceleration = velocity/time Velocity = time * acceleration =====================
This is imposible to calculate. In order to find acceleration, knowlege of at least 3 of these variables must be given: initial speed, final speed, distance, and time.
The speed at the end of the time is (speed at the beginning of the time) plus (acceleration x length of time)
It really depends what information you are given. In the simplest case, you use the definition of acceleration as delta(speed) / time. That is, you divide the change (delta) in speed, and divide by how long it takes for this change in speed. This gives you the average acceleration over the given time. If you assume a constant acceleration, it is also the instantaneous acceleration at any moment.
You can calculate the instantaneous speed of an object through calculus using derivatives. You can more easily find the instantaneous speed of an object if there is constant acceleration by multiplying the rate of acceleration by time, then adding the initial velocity when time was equal to zero.
Acceleration = Change in Speed divided by Time over which the change takes place. If acceleration is constant then Acc = [Final Speed - Initial speed] / Time If not, Acc = gradient of Speed-Time graph.
Acceleration is the change in velocity with time, for linear (constant) acceleration it is calculated by: (End Speed -Start Speed)/time taken
Find out the time using speed and acceleration, (time=speed/acceleration) and then use it to find out uniform velocity. From that find out uniform acceleration. (as uniform acceleration is equal changes of velocity over equal intervals of time)
Acceleration is the change in velocity ("speed") over time.
Acceleration is negative.
The same as the acceleration rate. Measure the speed at one moment of time, measure the speed at another moment of time, calculate the difference, divide by the time elapsed.
