Introduction: presentation and purpose of the course; table of contents

The physical quantities and their measurement: The physical quantities: what they are, direct and indirect measurements, fundamental and derived quantities. The units of measurement in the SI, CGS and practical systems. Prefixes for power of 10. Scalar and vector quantities; components of a vector and versors; operations between vectors; scalar and vector product. Cartesian coordinate coordinates.

Kinematics of points: The material point. The trajectory. The position vector. The velocity vector, the average velocity. The vector acceleration, the average acceleration. Kinematics in one-dimension: uniform linear motion, uniformly accelerated rectilinear motion. Uniform circular motion: outline. Harmonic motion.

Dynamics: inertial frame of reference. The inertial mass. Newton's laws. Examples of forces: gravitational force, weight force, normal force, spring force, friction force. Moment of a force. Center of gravity.

Biomechanics: Statics: equilibrium of rigid bodies; example: the hip joint. Constraints. The levers and their classification; examples of levers of human body: the articulation of support of the head, foot in lifting, the elbow joint.

The deformable bodies: stress, strain, elasticity, Young’s modulus; example: compression and tension of the human femur.
