First equation of motion relates four kinematic variables - Final Velocity, Initial Velocity, Acceleration and Time.
In this video, we learn how to use the Calculus method to derive the first equation of motion, v = u + at, where,
v = final velocity
u = initial velocity
a = acceleration
t = time.
Then we look at how and when to apply this equation. Equations of motion can only be applied in constant acceleration problems. Check out more in this video!
