2. 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

3. 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

4. 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

5. 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 =
