Average acceleration = Change in speed/time
so
Time = Change in speed/Average acceleration
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.
Calculate the gradient of the curve which will give the acceleration. Change the sign of the answer to convert acceleration into retardation.
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.
Acceleration = (change in speed) divided by (time interval)
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.
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.
Speed = Time x acceleration
speed equals to acceleration into time
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.
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.
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.
