Balance and Stability
Centre of mass: The center of mass is a position defined relative to an object or system of objects. It is the average position of all the parts of the system, weighted according to their masses. For simple rigid objects with uniform density, the center of mass is located at the centroid.
Line of gravity: Line of gravity is an imaginary vertical line from your centre of gravity to the ground or surface the person is on. The closer the line of gravity is to the centre of the base support the more balanced the person will
Centre of gravity: A point from which the weight of a body or system may be considered to act. In uniform gravity it is the same as the centre of mass. The closer the centre of gravity is to the base of support the more stable I can become.
Base of support: The base of support is the area around the outside edge of the sections of your body in contact with the ground/surface.

Newtons Laws

For every action, there is an equal and opposite reaction.
A body at rest will remain at rest, and a body in motion will remain in motion unless it is acted upon by an external force
Projectile Motion
Although a projectile is an object that is only affected by gravity, there are other forces which are acting upon the projectile. Forces such as air resistance, spin and friction all act upon the projectile, but because the forces are minuscule compared to the force of gravity, they are negligible when calculating projectile motion.
A projectile is composed of both a Vertical motion component and a horizontal motion component. Both directional motions are independent to each other, and therefore, are calculated and approached separately. This is because the two independent motions are perpendicular to each other, and therefore, they must be discussed independently.
A projectile is defined as any object that has only the force of gravity acting upon it. Projectile motion is the motion or trajectory that the projectile follows when in the air.
