📌 Biomechanics - Application of mechanical principles to living organisms
📌 Kinesiology - Study of human movement
📌 Sports Medicine - Clinical and scientific aspects of sports and exercise
📌 Occupational Biomechanics - Prevention of work-related injuries & performance improvement

📌 Kinematics - Study of motion description (sequence & timing)
📌 Kinetics - Study of forces involved in motion

📌 Statics - Systems with no acceleration (can be stationary)
📌 Dynamics - Systems with acceleration

📌 Anatomical Reference Position

Standing upright
Arms at sides
Palms facing forward

📌 Sagittal Plane (Left & Right) - Frontal Axis

Flexion, Extension

📌 Frontal Plane (Front & Back) - Sagittal Axis

Hip Abduction, Hip Adduction

📌 Transverse Plane (Top & Bottom) - Longitudinal Axis

Rotation, Pronation, Supination

📌 Mass - Amount of matter in an object (kg)
📌 Weight - Gravitational force acting on a body

wt = ma (gravity = -9.81 m/s²)

📌 Inertia - Resistance to change in motion (higher mass = higher inertia)
📌 Force - A push or pull acting on a body (F = ma)
📌 Center of Gravity - Point where body weight is equally balanced
📌 Pressure - Force per unit area (P = F/A)
📌 Stress - Distribution of force within a body (Stress = F/A)
📌 Volume - 3D space occupied by a body (V = l × w × h)
📌 Density - Mass per unit volume (Density = Mass/Volume)
📌 Torque - Rotational effect of an eccentric force (T = F × d)
📌 Impulse - Force applied over time (J = F × t)

📌 Compression - Pressing force through the body
📌 Tension - Stretching force through the body
📌 Shear - Force parallel to the body (e.g., ACL tear)
📌 Bending - Tension on one side, compression on the other
📌 Torsion - Twisting force (e.g., snake bite)
📌 Combined Loading - Multiple forces acting together
