This document provides a lesson plan for a 9th standard physics lesson on gravitation and the center of gravity. The 40-minute lesson will use an activity-oriented approach to teach terms like center of gravity and equilibrium position. Students will learn that the center of gravity is the point where the torque due to gravity forces vanishes and that near Earth's surface, the center of gravity and center of mass are the same point. The lesson will include showing explanatory videos and doing an experiment to reinforce the concepts.

2. FACTS
 centre of gravity is the point in a body around which the resultant torque due to gravity forces vanishes.
 Near the surface of the earth, where the gravity acts downward as a parallel force field, the center of gravity and the cente r of mass of an
arbitrary body are the same.
CONCEPTS
centre of gravity- The center of mass is the unique point at the center of a distribution of mass in space that has the property that the weighted position vectors
relative to this point sum to zero. In analogy to statistics, the center of mass is the mean location of a distribution of mass in space.
