Detailed explanation-1: -Acceleration (a) is the change in velocity (v) over the change in time (t), represented by the equation a = v/t.
Detailed explanation-2: -vf = final velocity vi = initial velocity a = acceleration ∆x = displacement Use this formula when you don’t have ∆t. F = force m = mass a = acceleration Newton’s Second Law. Here, F is the net force on the mass m. g = acceleration due to gravity The weight of an object with mass m.
Detailed explanation-3: -Final Velocity Formula vf=vi+at. For a given initial velocity of an object, you can multiply the acceleration due to a force by the time the force is applied and add it to the initial velocity to get the final velocity.
Detailed explanation-4: -a = (v f-v i) / t; a = 2 × (d-v i × t) / t²; a = F / m; 02-Feb-2023
