2.5 Motion Equations for Constant Acceleration

What variables do the kinematic equations relate?

Displacement, initial velocity, final velocity, acceleration, and time

When should you use v² = v₀² + 2a(x - x₀)?

When you don’t have time (t)

Which kinematic equation doesn’t include final velocity?

x = x₀ + v₀t + 1/2at²

Which kinematic equation doesn’t include displacement?

v = v₀ + at

at does each variable in the equations stand for?

• x: final position

• x₀: initial position

• v: final velocity

• v₀: initial velocity

• a: acceleration

• t: time
