Lecture
Gravitation: Universal Law and Free Fall
Description
This lecture covers the universal law of gravitation, explaining how two masses attract each other with a force proportional to the product of their masses and inversely proportional to the square of the distance between them. It also delves into free fall, describing how objects accelerate towards the Earth due to gravity, with examples like vertical motion and the concept of weight. Additionally, it discusses forces of contact and tension, analyzing scenarios such as a pendulum and a block on an inclined plane. The lecture concludes with a detailed explanation of forces acting on objects in different situations, including the role of tension, friction, and support.
