unacademy Speed & Velocity By Hemant Kumar Sharma B. Tech (M.E.) GATE Qualified

Speed Speed is the distance traveled per unit of time. Scalar Quantity SI meter per second (m/s) Speed DIStance Time Uniform Speed Speed Non-Uniform Speed

Velocity The rate of change of displacement of a body with the passage of time is known as velocity. Vector Quantity SI - meter per second (m/s) Displacement VelcoltyTime Uniform Speed Speed Non-Uniform Speed

Average Speed The average speed of an object is the total distance traveled by the object divided by the elapsed time to cover that distance. It's a scalar quantity which means it is defined only by magnitude. Scalar Quantity SI meter per second (m/s) Total Distance Avg. Speed - Total Time

Average Velocity The average velocity of an object is the net displacement traveled by the object divided by the elapsed time. Vector Quantity SI meter per second (m/s) Net Displacement Total Time Avg. Velocity =
