The material of Physics of the 3rd high school includes the chapters:
ISSUE A'
- ELECTROMAGNETISM
In this chapter we will learn about the creation and characteristics of a magnetic field, we will see what kind of magnetic field different current-carrying conductors create and conversely we will see the force that current-carrying conductors receive if they are inside a magnetic field.
Getting to know electromagnetic induction is also very important, where we will see what the magnetic flux is, how the EMF is created by induction and, by extension, the induced current.
ISSUE B'
- ALTERNATING CURRENT
Here we will see how alternating voltage and alternating current are created and how Joule's Law applies to alternating current circuits.
ISSUE III
- Mechanical oscillations
- Fluids in motion
- Solid body mechanics
- Crashes
Mechanical oscillations:
In 3rd grade we will deal with a very interesting periodic phenomenon, the simple harmonic oscillation.
We will also consider oscillations whose amplitude is reduced - the decaying oscillations - and oscillations in which we impart energy to the oscillating body - the forced oscillations.
Finally, we will deal with the case where the body participates in more than one oscillation (compound oscillations).
Fluids in motion:
With the designation "liquids" we name liquid and gaseous bodies, which - unlike solids - do not have their own shape but take the shape of the container that contains them.
We move in fluids (atmospheric air or sea water), we transport huge amounts of fluids with pipes, we exploit the energy of fluids to solve our practical problems.
The development of technology in these areas was based on the study of the laws that govern the movement of fluids and which we will deal with in this chapter.
Solid Mechanics:
In fact, all bodies have dimensions and therefore, in addition to performing translational motion, they can change orientation in space, that is, perform rotational (rotational) or even complex motion, that is, a combination of translational and rotational motion.
If forces are applied to a solid body, the body deforms, more or less and permanently or temporarily. Hypothetical solids that do not deform when forces are applied to them are called mechanical solids.
In this chapter we will deal with the study of the balance and motion of mechanical solids.
Shocks:
When two bodies collide, for example when they hit two billiard balls, the kinetic state of them or at least one of them changes abruptly. These sudden changes in motion are caused by the strong forces that develop between the colliding bodies,
the duration of their contact.
The student will be taught the laws that can describe impact phenomena as well as how to apply them.
