Motion

Distance is the total path length

Distance is the total path length covered by an object (scalar quantity), while displacement is the shortest distance between initial and final positi

Uniform motion occurs when an object

Uniform motion occurs when an object covers equal distances in equal time intervals (like a car on highway at constant speed). Non-uniform motion invo

Speed is distance traveled per unit

Speed is distance traveled per unit time (scalar), calculated as s/t. Velocity is displacement per unit time with direction (vector). Average speed =

Acceleration is the rate of change

Acceleration is the rate of change of velocity, calculated as a = (v-u)/t, where u is initial velocity, v is final velocity, and t is time. Positive a

Distance

Distance-time graphs show how distance changes with time. Straight lines indicate uniform motion; curved lines show non-uniform motion. Velocity-time
