This lesson covers the theory, application and graph representation of Newton's Laws of Universal Gravitation. The are two examples that will help with the understanding of how to calculate for and distance between two objects that attract each other. This is relevant for IEB and NSC/SCE exams in South Africa but it is also applicable for other international curricula (Cambridge IGCSE, O-level, etc)
