Linear motion is motion in a straight line (as opposed to circular motion). Here we explain Newton’s laws of motion, mass, inertia, momentum, speed, velocity, distance, displacement and graphs of motion.
Angular Motion
Angular momentum includes rotating bodies, levers, stability, moment of force/torque, axis of rotation, moment of inertia and angular momentum.
Forces
A force is a push or a pull which alters the state of motion of a body and is measured in Newtons (N). Here we cover balanced and unbalanced forces, friction, air resistance, impulse, force-time graphs, and free body diagrams.
Fluid Mechanics
Fluid mechanics or fluid dynamics comes into sport a lot and covers air resistance, drag, projectiles, spin on balls and Bernoulli principle and lift force.
