Contour Lines

The video introduces contour lines, explaining their role in representing equal elevation and gravitational potential energy. Through a practical activity using a bowl and water, the concept of contour lines is demonstrated. The video further explores the properties of contour lines, their application in topographic maps, and how they can be visualized in three dimensions. Finally, it draws an analogy between contour lines and electric field lines, setting the stage for further exploration in the next video.

Discuss the relationship between gravitational potential energy and contour lines.
