Acceleration. Rectilinear motion with constant acceleration. Instant speed.
Acceleration shows how quickly the speed of a body changes.
t 0 = 0c v 0 = 0 m/s Velocity changed to v = v 2 - v 1 during
t 1 = 5c v 1 = 2 m/s time interval = t 2 - t 1. So in 1 s the speed
t 2 = 10c v 2 = 4 m/s of the body will increase by =.
t 3 = 15c v 3 = 6 m/s = or = . (1 m/s 2)
Acceleration – vector quantity, equal to the ratio of the change in speed to the period of time during which this change occurred.
Physical meaning: a = 3 m/s 2 - this means that in 1 s the velocity module changes by 3 m/s.
If the body accelerates a>0, if it slows down a
Аt = ; = + at instantaneous speed bodies at any given time. (Function v(t)).
Moving at uniformly accelerated motion. Equation of motion
D 
For uniform motion S=v*t, where v and t are the sides of the rectangle under the speed graph. Those. displacement = area of the figure under the velocity graph.
Similarly, you can find the displacement for uniformly accelerated motion. You just need to find the area of the rectangle and triangle separately and add them up. The area of the rectangle is v 0 t, the area of the triangle is (v-v 0)t/2, where we make the replacement v – v 0 = at. We get s = v 0 t + at 2 /2
s = v 0 t + at 2 /2
Formula for displacement during uniformly accelerated motion
Considering that the vector s = x-x 0, we get x-x 0 = v 0 t + at 2 /2 or take out starting coordinate to the right x = x 0 + v 0 t + at 2 /2
x = x 0 + v 0 t + at 2 /2
Using this formula you can find the coordinates of an accelerating body at any time
When moving equally slow before the letter “a” in formulas, the + sign can be replaced with -
The VAMOS Spanish Language Center invites children and teenagers who want to learn Spanish. This course designed taking into account the peculiarities of perception of the material by young listeners. The methods of teaching Spanish to children differ from those for adults.

Duration
The full course for children consists of eleven blocks (level B2).
children from 6 to 8 years old– 30 hours, 15 weeks. Classes are held once a week for 2 academic hours(45 min.) with a break of 10 min.
Duration of one block for children from 9 to 11 years old– 30 hours, 12 weeks. Classes are held once a week for 2.5 academic hours (45 minutes) with a 10-minute break.
Teenagers study from textbooks "Club Prisma" Publishing house "Edinumen". The book consists of two parts, for use in the classroom and at home, and contains a pleasant addition - a key that allows you to download interesting Additional materials in the Internet.
Also, the Spanish course for teenagers uses additional materials from textbooks "GenteJoven" And "Vacaciones en español".
Duration
The Spanish course for teenagers from 12 to 16 years old consists of six blocks of 40 hours and includes levels from beginner A1 to intermediate B1. Classes are held 2 times a week for 2.5 academic hours (45 minutes) with a 10-minute break.
This book is tutorial for schoolchildren starting to learn Spanish. The material is divided by topic. Each one comes with dictionaries with new words to learn, as well as short, simple stories and dialogues. The structure of the Spanish language is revealed in the “A Little Grammar” sections. With the help of this manual, schoolchildren can study at home independently, resorting to the help of adults only in cases where additional clarification is required.
Un and una are indefinite articles that are placed before nouns that are unknown to us, or that are being spoken about for the first time. The indefinite article un is placed before nouns male, a una - before nouns female. The gender of nouns in Spanish and Russian may not be the same.
