Mastering Newton's Laws and Equilibrium

This course covers the fundamental principles of Newton's laws of motion and the concept of equilibrium in static systems. It begins with an in-depth exploration of Newton's laws, explaining how they govern the motion of bodies and how they are interconnected. For instance, the course illustrates how pushing a wall results in the wall pushing back with an equal force, demonstrating Newton's third law. The course then delves into the concept of equilibrium, particularly in static systems, explaining how the summation of all forces acting on a body must be zero for the body to be in equilibrium. The course also introduces the concept of free-body diagrams, demonstrating how to use them to solve problems involving forces and equilibrium. For example, the course shows how to calculate the force required to hold a block in equilibrium on an inclined plane. The course concludes with a discussion on the concept of rigid body systems, focusing on systems of planar rigid bodies.
