Change in Velocity Formula:

Change in velocity, often represented as ΔV, is a concept from kinematics that describes the difference in velocity of an object over a period of time due to acceleration.

Change in velocity, ∆V_(m/s)  in metres per seconds is calculated by multiplying the acceleration, a_(m/s2) in metres per second squared and change in time, ∆t_(s) in seconds.

Change in velocity, ∆V_(m/s)  = a_(m/s2) * ∆t_(s)

∆V_(m/s)  = change in velocity in metres per seconds, m/s.

a_(m/s2) = acceleration in metres per second squared, m/s².

∆t_(s) = change in time in seconds, s.

Change in Velocity Calculation:

1.A car accelerates from rest at a constant rate of 2 m/s² for 5 seconds. Calculate the change in its velocity.

Given: a_(m/s2) = 2m/s², ∆t_(s) = 5s.

Change in velocity, ∆V_(m/s)  = a_(m/s2) * ∆t_(s)

∆V_(m/s)  = 2 * 5

∆V_(m/s)  = 10m/s.

2.Suppose an airplane accelerates at 4 m/s², and the change in velocity observed is 80 m/s. Calculate the time interval over which this acceleration occurred.

Given: a_(m/s2) = 4m/s², ∆V_(m/s)  = 80m/s.

Change in velocity, ∆V_(m/s)  = a_(m/s2) * ∆t_(s)

∆t_(s) = ∆V_(m/s)  / a_(m/s2)

∆t_(s) = 80 / 4

∆t_(s) = 20s.
