Biomechanics

Fluid mechanics or fluid dynamics come into the sport a lot and covers air resistance, drag, projectiles, spin on balls, and the Bernoulli principle and lift force. Spin Spin is created by applying a force that is off-centre to the object being thrown (or kicked) at the point of release. The effects of spin are

Angular motion includes rotating bodies, levers, stability, a moment of force/torque, the axis of rotation, a moment of inertia, and angular momentum. Lever Systems A lever is a rigid bar that moves on a fixed point called the fulcrum when a force is applied to it. Movement is made possible in the human body by

Linear motion simply means motion in a straight line (as opposed to circular motion or rotation). In order to talk about linear motion scientifically, we need to be familiar with mass, distance, displacement, speed, velocity, and acceleration. Here we explain Newton’s laws of motion, mass, inertia, momentum, speed, velocity, distance, displacement, and graphs of motion.

A force is a push or a pull that alters the state of motion of a body and is measured in Newton’s (N). Here we cover balanced and unbalanced forces, friction, air resistance, impulse, force-time graphs, and free-body diagrams. Free Body Diagrams Free body diagrams are used to show which forces are acting on a
