Dynamics: Force and Newton’s Laws of Motion and Applications: Friction, Drag and Elasticity
Part 3: Dynamics: Force and Newton’s Laws of Motion and Applications: Friction, Drag, and Elasticity
This part introduces dynamics, the study of the relationship between forces and motion. Building on the kinematics concepts developed in the previous part, you will learn how forces change an object’s motion through Newton’s three laws of motion. These principles explain phenomena ranging from the movement of athletes and vehicles to the forces acting on bones, muscles, and joints in the human body.
You will also study common types of forces encountered in everyday life, including weight, normal force, tension, friction, drag, and elastic forces. Along the way, you will develop systematic problem-solving strategies for analyzing forces acting on objects and explore how these concepts apply to biomechanics, medical devices, transportation, and engineering. The part concludes with an introduction to the four fundamental forces of nature, providing a bridge to later topics in electricity, magnetism, and modern physics.
