# What is the acceleration in science if you know average speed and time?

If you know average speed then you cannot determine the acceleration: the very nature of being a average hides all the increases and decreases in speed which are the accelerations (technically, acceleration is change of speed in a direction).

All average speed tells you is the constant speed at which you require to travel to cover the given distance in the given time; as the speed is constant, the acceleration is zero. Study guides

If you know only average speed and time, you don't have enough information.You need to work with VELOCITIES - not with speeds.

And you need to know the DIFFERENCE between the final velocity and the initial velocity. Knowing the average velocity doesn't help (for a given average velocity, the acceleration could be anything).

The calculation is to divide the difference in velocity (i.e., final velocity minus initial velocity) by the time elapsed. That will give you the AVERAGE ACCELERATION.  Earn +20 pts
