Most of the phenomena in the world around you are, at the fundamental level, based on physics, and much of physics is based on mechanics. You will understand with greater depth many of the wonders around you in everyday life, in technology, in the universe at large. That, in turn, will lead you to look further and deeper into the world and the universe around you. Meanwhile, we think you'll have some fun, too.
This course uses rich multimedia tutorials to present the material: film clips of key experiments, animations and worked example problems, all with a friendly narrator. You'll then do a range of interesting problems to practise what you've learnt, and for assessment. You will use your ingenuity to come up with two experimental investigations using simple, everyday materials (plus a computer).
Week one: Introducing physics, mechanics and this course. And taking you through a range of tools needed for physics (and for much of science): units, scientific notation, dimensions, vectors, graphing quantities, significant figures, handling errors. (The course can be taken without calculus, but calculus is introduced in one of the toolkit resources provided)
Week two: Motion in one dimension. Especially analysing motion with constant velocity or constant acceleration. Frames of reference and relative motion
Week three: Kinematics in two dimensions including the motion of projectiles and motion in a circle
Week four: Newton's laws of motion
Week five: Weight vs mass. Contact forces, their normal and frictional components. Hooke's law and springs.
Week six: Newton's second law in terms of kinetic energy. Introducing potential and internal energy. Conservation laws. Energy transformation and power
Week seven: Newton's second law in terms of momentum. Collisions and conservation of momentum
Week eight: Newton's law of universal gravitation. Gravitational potential energy and escape velocity. Kepler's laws and the motion of satellites, planets and galaxies.
Mechanics is the basis of much of physics, engineering and other technological disciplines. It begins by quantifying motion, and then explaining it in terms of forces, energy, momentum and forces including gravity. This allows us to analyse the operation of many familiar phenomena around us, but also the mechanics of planets, stars and galaxies.
