Laws of Motion

Distance is the actual path length

Distance is the actual path length traveled by an object, while displacement is the shortest straight-line distance between starting and ending points

Speed is distance traveled per unit

Speed is distance traveled per unit time (scalar), while velocity is displacement per unit time (vector). Speed = Total distance/Time, Velocity = Disp

Uniform motion occurs when an object

Uniform motion occurs when an object covers equal distances in equal time intervals. Non-uniform motion occurs when unequal distances are covered in e

Acceleration is the rate of change

Acceleration is the rate of change of velocity. a = (v-u)/t, where v is final velocity, u is initial velocity, and t is time. It can be positive (spee

Three fundamental equations relate displacement (s)

Three fundamental equations relate displacement (s), initial velocity (u), final velocity (v), acceleration (a), and time (t): v = u + at, s = ut + ½a
