Kinematics: Velocity

Final velocity under constant acceleration.

Formula

v=u+atv = u + at

Variables

uInitial velocity
aAcceleration
tTime

Example

Starting at 5 m/s and accelerating 2 m/s² for 3 s: v = 5 + 2·3 = 11 m/s.

Did You Know?

These kinematic equations assume constant acceleration — exactly the case for objects in free fall.
