# How To Measure Acceleration Time Accurately?

Can you remember a time when you got in your vehicle and pushed your accelerator pedal to the floor in order to see how fast you could take off from a dead stop? Whether you realize it or not, you were attempting to measure your vehicle’s acceleration rate. Acceleration can be calculated in different ways such as:

• an applied force that changes the direction or speed of an object

• in feet or meters per second

• the time involved in changing an object’s velocity

The formula for calculating the average rate of acceleration of an object involves 3 variables:

V1 – initial velocity

V2 – final velocity

?t – duration of acceleration time

The formula appears as: Acceleration (a) = Change in Velocity (?v) / Time Interval (?t) = (v2 – v1) / (t1 – t2). The final velocity minus the initial velocity and divided by the length of time involved equals the rate of acceleration.

There are two considerations where this formula is concerned. First, if you are in a country that uses the metric system, your results should be expressed in meters per second squared. Secondly, if the initial velocity is greater than the final velocity, the result will be expressed as a negative number. This means that the formula can be used to calculate the rate at which an object is decreasing speed or slowing down.

On a closing note, acceleration also occurs when an object is acted upon by a force which in turn causes it to change direction and speed towards that force which is pulling or pushing it. You can calculate the rate at which a force accelerates by using the variables of “Force” and “Mass.” In this case, Force is measured in “Newtons” and Mass is measured in kilograms. So it the rate of acceleration is calculated using the metric system.
