Concept of Position, distance, displacement, speed, and velocity

Image
Position, distance, displacement, speed, velocity • Distance time graph At the end of this lesson,  the students should be able to: • Distinguish between distance and displacement in a translational motion • Distinguish between speed and velocity • Plot a distance-time graph and deduce the speed of motion from the gradient or slope of the graph • Determine speed and velocity when simple problems are set involving distance or displacement and time
