SYLLABUS/CONTENT

MATERIAL POINT MECHANICS:

Physical quantities and unit of measurement systems:

• Physical quantities include mass, length, time, and force.
• Measurement systems include the International System of Units (SI) and others like the CGS system.

KINEMATICS:

• Definition of speed and acceleration: Speed is the rate of change of position, while acceleration is the rate of change of velocity.
• Expression in a system of orthogonal Cartesian coordinates: Speed and acceleration can be expressed as vectors using Cartesian coordinate components.
• Straight-line motion: Motion along a straight path with constant velocity or zero acceleration.
• Generic plane motion and composition of movements: Describes motion in a plane and combining individual motions to determine overall motion.
• Circular motion: Motion along a circular path, described in Cartesian or polar coordinates.
• Derivative of a verse: Please provide more information or clarify the term.

• DYNAMICS:

• Newton's Law: First law (inertia), second law (F = ma), and third law (action-reaction).
• Inertial reference systems: Frames of reference where Newton's laws hold true.
• Examples of force laws: Gravity, electromagnetic forces, and Hooke's law for springs.
• Static and dynamic friction force: Friction opposing motion at rest and in motion, respectively.
• Elastic force and Hooke's law: Force exerted by a spring-like object following a linear relationship.

• Definition of scalar product: Dot product of two vectors resulting in a scalar.
• Work of a force: Work is the product of force and displacement in the direction of force.
• Work-energy Theorem: Work done on an object equals its change in kinetic energy.
• Conservative and non-conservative forces: Conservative forces are path-independent, non-conservative forces are path-dependent.
• Conservation of mechanical energy: Total mechanical energy remains constant in the presence of only conservative forces.
• Potential energy: Energy due to an object's position or configuration, such as gravitational or elastic potential energy.
• Calculation of potential energy by weight strength and elastic force: Potential energy formulas for weight and elastic forces.

DEFINING AMOUNT OF MOTION AND ANGULAR MOMENTUM:

• Amount of motion: Refers to momentum, the product of mass and velocity.
• Angular momentum: Measure of rotational motion, product of moment of inertia and angular velocity.
• Relationship between angular momentum and moment of forces: Conservation of angular momentum when no external torques act.
• The motion of the simple pendulum:
• Motion of a mass attached to a string or rod suspended from a fixed point.
• Characterized by periodic oscillations, with the period depending on length and acceleration due to gravity.

MECHANICS OF SYSTEMS:

• Dynamics of systems: Study of motion and behavior of multiple interacting objects.
• Cardinal equations: First equation relates net force, mass, and acceleration.
• Energy work theorem for material point systems: Relates work done on a system to its change in mechanical energy.
• Elastic and totally anelastic collisions: Conservation of momentum and kinetic energy in collisions.
• Motion of rigid bodies: Study of translation and rotation of rigid objects.
• Relationship between axial moment and angular acceleration: Torque equals moment of inertia times angular acceleration.
• Kinetic energy in rotating and roto-translational motion: Combination of kinetic energy of translation and rotation.
• Pure rolling motion: Motion where a rigid body rolls without slipping.
• Work for a rigid body: Work done on a rigid body by a force.
• Gyroscopic motion: Motion of spinning objects with unique rotational properties.

• THERMODYNAMICS:

• Introduction to thermodynamic systems: Open and closed systems, thermodynamic variables.
• Zeroth principle of thermodynamics and thermometric scales: Temperature and thermal equilibrium.
• Boyle's and Gay-Lussac's laws: Relationship between pressure, volume, and temperature of a gas.
• Internal energy: Total energy of a system due to its microscopic components.
• First law of thermodynamics: Conservation of energy for thermodynamic systems.
• Definition of specific heat: Heat capacity per unit mass or per mole of a substance.
• Relationship between specific heat and constant volume/pressure: Heat capacities at constant volume and pressure.
• Heat conduction: Transfer of heat through conduction and radiation.
• Latent heat in phase transitions: Heat absorbed or released during phase changes.

EXAM DESCRIPTION

See the Exam Description for the parent 80527 course which describes the exam for both FIS/01 and FIS/03 modules.

ASSESSMENT METHODS

See the Exam Description for the parent 80527 course which describes the exam for both FIS/01 and FIS/03 modules.

The written test verifies the degree of learning by verifying the ability to work out the various parts of the program.

Usually mechanical and electromagnetic exercises are common to most of the General Physics Courses of the Polytechnic School.

The oral examination verifies the degree of knowledge and understanding of the subjects covered by the program, the ability to clearly and accurately disclose the acquired knowledge and the ability to apply such knowledge to the resolution of problems.
