What is inital velocity?
There are two methods, it depends on what variables you have: 1. Subtract the initial velocity from the final velocity and divide that whole term by the time (Vf- Vi)/t = a 2. Square both the initial velocity and the final velocity and subtract the squared inital velocity from the squared final velocity and that answer by two times the distance (Vf^2 - Vi^2)/2d = a
Initial velocity is the velocity an object begins with Final velocity is the velocity at which the object ends up in Say a car is travelling at 13 m/s and then crashes into a wall stopping it it's intitial velocity was 13 m/s and it's final velocity is at 0 m/s or Say a car starts off at 5 m/s but then accelerates from 5 m/s to 10 m/s. It's inital velocity would be 5…
The first answer is backward. Acceleration = (final velocity - initial velocity)/total time. For deceleration the formula is the same, the answer will just be negative. Agreed. In physics, there is no "deceleration", only negative acceleration. a = Δv / Δt There is no equation for "deceleration" as suggested below. Deceleration=(original velocity-final velocity)/Time Deceleration In Motion Deceleration = inital speed - final speed / total time taken
