Answer:
THE EARTH'S SURFACE IS A COMMON REFERENCE POINT FOR DETERMINING POSITION AND MOTION. THE RATE AT WHICH AN OBJECT MOVES IS ITS SPEED. THE SI UNIT FOR SPEED IS METERS PER SECOND (M/S). AVERAGE SPEED= TOTAL DISTANCE/TOTAL TIME. THE SPEED OF AN OBJECT IN A PARTICULAR DIRECTION IS THE OBJECT'S VELOCITY.
