#### Objective

At the end of this course, students will be able to: 1. Specify the characteristics of the motion of a point mass. 2. Apply Newton's laws. 3. Apply and verify the conservation laws of energy, and of linear momentum in collisions. 4. Describe the state of equilibrium of a solid. 5. Apply the fundamental principle of hydrostatics. 6. Distinguish a real fluid from an ideal fluid. 7. Study the motion of a ball through a viscous fluid. 8. Study the cyclic transformations of a thermodynamical system. 9. Compare the performance of a heat engine to that of Carnot’s engine.

#### Content

Kinematics: position vector, velocity vector and acceleration vector of a point mass. Study is restricted to Cartesian and polar coordinates. Dynamics: Types of forces, Newton's three laws of motion. Applications: motion on an inclined plane, free fall, satellites, central forces. Rotation: Moment of a force, moment of inertia, angular momentum. Energy: work of a constant force, work of the weight of a body, work of a frictional force and of the tension force in a spring. Theorem of kinetic energy. Conservation laws: conservation and non-conservation of mechanical energy, conservation of linear momentum and angular momentum. A solid in equilibrium: Conditions of equilibrium. Hydrostatic: fundamental principle and hydrostatics. The buoyant force. Fluid dynamics: Bernoulli's theorem, viscosity, Poiseuille's law, the motion of a spherical body in a viscous medium. First law of thermodynamics: Enthalpy, energetic treatment of thermal cyclic - processes. Concept of work. Second law of thermodynamics: Performance of a heat engine, Carnot's theorem. Entropy.
