The science of everyday phenomena.
This is the study of kinematics. We derive the equations of motion from first principles, then apply them to the description of motion of everyday objects in both one and two dimensions, such as projectile motion.
The causes of motion are studied in the field of mechanics. Newton’s three laws of motion are investigated, then applied to systems of forces in multiple dimensions, including friction and drag forces.
The concepts of energy, work done and power are considered in this chapter. We also look at the inter-relation between all three of them and derive the expression for the conservation of potential and kinetic energy through the work-kinetic energy theorem.
The conservation of linear momentum in introduced, along with the topics of center of mass and center of gravity. The equations of rocket motion are derived as an example of systems with varying mass.
Systems of particles and rigid body rotation are considered with units of angular measurements. The equations of rotational motion are introduced and applied to the concepts of torque and angular momentum.
The equations of motion along with the mechanics of particles are applied to fluids. The definitions of pressure and density are explained and applied to principles such as Pascal, Archimedes and Bernoulli. The principle of flight and the equation of continuity are also studied.
The propagation of energy through wave motion is analyzed. Concepts such as wave interference, oscillations, seismology, Earthquakes, sound and the Doppler Effect are investigated.
Definitions of heat and temperature are introduced. Heat transfer through conduction, convection and radiation are studied, along with the ideas of specific heat as it applies to the laws of thermodynamics.
Newton’s Universal Law of Gravitation is explained and the acceleration due to Earth’s gravity “g” is calculated. The concept of gravitational potential energy is examined, then applied to the calculation of a planet’s escape velocity. These ideas are then applied to satellites in orbit and Kepler’s laws of planetary motion.
