๐Ÿ“š Quick Study Guide

  • โฑ๏ธ Acceleration is the rate at which velocity changes over time.
  • ๐Ÿ“ It's a vector quantity, meaning it has both magnitude and direction.
  • ๐Ÿงฎ The average acceleration formula is: $a = \frac{\Delta v}{\Delta t} = \frac{v_f - v_i}{t_f - t_i}$, where $v_f$ is the final velocity, $v_i$ is the initial velocity, $t_f$ is the final time, and $t_i$ is the initial time.
  • โž• If acceleration and velocity have the same sign, the object speeds up.
  • โž– If acceleration and velocity have opposite signs, the object slows down.
  • ๐Ÿ“ The standard unit of acceleration is meters per second squared ($m/s^2$).
  • ๐Ÿ’ก Constant acceleration means the velocity changes at a steady rate.
