Motion – Speed & Velocity (Part -3)

• Speed is defined as the ratio of distance travelled to the time taken to cover that distance.
• Speed is the distance travelled in unit time.
• Speed = Distance Covered/Time Taken
• Average Speed = Total Distance/Total Time (In non-uniform motion)
• SI Unit of Speed ⇒ m/s

• Velocity is defined as the distance travelled in a specific direction in unit time. (displacement in unit time)
• Velocity is the rate of change of displacement in unit time.
• Velocity = Displacement/Time Taken
• SI Unit of Velocity ⇒ m/s
