A Bridging Course to First Year Physics with Peter Eyland

This is a preparatory course for those taking University Physics who have not done Physics before. It gives an introduction to the language, style and techniques of Physics. This is done with some basic terms and thinking about how to describe motion and its causes.

Course Content

 Memory and Study Greek alphabet The International System of units Lecture 1 • Physics as the nature of things • Knowledge and Belief (Zeno's paradox) • Average and Instantaneous Speed • Position/time graph to speed/time graph • speed/time graph to position/time graph Position and Speed Lecture 2 • Average and instantaneous acceleration • Speed vs time graph to acceleration vs time graph • Acceleration vs time graph to speed vs time graph • Constant acceleration graphs and equations Lecture 2a The techniques of finding slopes (how quickly something changes in time or space) and finding areas (the effect of something through time or space) will now be applied to position, speed and acceleration. Speed and Acceleration - examples. Fully worked answers are provided. Speed and Acceleration examples Lecture 2b More Speed and Acceleration - examples. Some practice questions for you to try. More Speed and Acceleration examples Lecture 3 • Descartes and Cartesian co-ordinates • Vectors and scalars • Polar co-ordinates • Adding vectors sequentially and simultaneously • Subtracting vectors • Vector components and adding by components Vectors and Scalars Lecture 4 Vectors - example problems. Fully worked answers are provided. Vector Examples Lecture 5 • the viscous drag of the air it passes though, • air density variations (buoyancy), • the change of gravitational acceleration with height, • the shape and rotation of the object Projectiles Lecture 6 • More projectile motion examples. • Accelerations that change with time. Projectiles and Variable Acceleration Lecture 7 • Velocity and speed • Momentum as the quantity of motion • Newton's laws of motion • Internal and external forces Dynamics Lecture 8 Dynamics - example problems. Try these for practice.
