πŸ“š Quick Study Guide

  • πŸ“ Constant acceleration means the velocity changes at a steady rate.
  • ⏱️ Key kinematic equations (for constant acceleration in one dimension):
    • $v = v_0 + at$
    • $x = x_0 + v_0t + \frac{1}{2}at^2$
    • $v^2 = v_0^2 + 2a(x - x_0)$
  • ⚠️ Remember that these equations only apply when acceleration is constant.
  • βž• Vectors: Velocity and acceleration are vectors, so direction matters (+/-).
  • πŸ“ Projectile motion can be analyzed as constant acceleration in x and y directions.
