**Objectives**

Provide skills that will allow the students to relate the concepts learned with daily phenomena. Basic physical principles related to kinematics and dynamics. Static equilibrium. Physical properties of some materials.

**Program**

1 ? Unit Systems. Magnitudes. Vector calculus.

Physical quantity and order of magnitude. Scientific notation. International system of units (SI): base units and derived units. Physical quantities. Dimensional analysis of a physical quantity. Scalar quantity and vector quantity. Vector definition; representation in a system of orthogonal axes in two dimensions. Unit vectors. Mathematical operations with vectors.

2 ? Mechanics: kinematics basic concepts. Position, displacement, average speed, instant velocity and average acceleration: SI units. Graphs in kinematics. Uniform circular motion: frequency, period, angular velocity, velocity.

3 ? Mechanics: interactions and forces. Force: definition and unit SI. Definition of some forces such as: weight, normal force, tension, friction, impulsion. Mass and body weight. Newton´s Law. Static equilibrium. Pression exerted by a force: definition and unit SI.

4- Mechanics: energy. Forms of energy. Potential and kinetic energy.

5- Mechanical properties of materials. Density and

relative density. Pressure in a liquid. Archimedes' Principle. Compressibility and Young Modulus.

6- Thermal properties of materials. Linear dilation. Linear dilation coefficient. Volumetric dilation. Heat capacity. Specific heat. Conduction convection and radiation heat transfer.

7- Porosity. Porous materials: real density and apparent density porosity. Determining the porosity of a material: method description.

**Evaluation Methodology**
