Average Velocity as a function of final and initial velocities

Average Velocity = (Initial Velocity + Final Velocity) / 2

Displacement as a function of final and initial velocities and time

Displacement = (Initial Velocity × Time) + ½at²

Final Velocity as a function of initial velocity, acceleration and time

Final Velocity² = Initial Velocity² + 2as

Final Velocity as a function of initial velocity, acceleration and displacement

Final Velocity = Initial Velocity + at

Displacement as a function of initial velocity, acceleration and time
