Driving Forces - Kinematics and the Geometry of Motion - Lecture 1

Explore the fundamental principles of motion and kinematics in this 59-minute Christmas Lecture from The Royal Institution, delivered by Leonard Maunder in 1983. Discover how the geometry of motion forms the foundation of engineering design and machine development, from the ancient invention of the wheel to modern space exploration and assistive technologies for the disabled. Learn about the physical forces that make things move and understand how our knowledge of motion continues to evolve, despite still being incomplete in many fundamental aspects. Examine the dual nature of driving forces - both the human motivations like curiosity, improvement, and adventure that push technological advancement, and the actual physical forces that create movement in the natural and engineered world. Delve into kinematic principles that underpin a vast array of machines and mechanical elements, providing the essential groundwork for understanding how engineers design systems involving motion across scales from atomic to astronomical.
