- How'd it go?
- I've got to do a make-up exam.
- Leykin, hey, Leykin! - What do you want?
- Leykin, may I help you prepare?
- Uh-huh... - That's wonderful!
We'll start tomorrow!

- Let's begin with physics. From the parallelogram of forces.
Leykin, write down the task conditions.
Let's suppose that a body is being acted upon by two forces
from different directions at an obtuse angle.
- "Obtuse"... Look at yourself!
- The first force is equal to... Leykin, are you writing?
- Force... Vector...
Force is something to reckon with!
- Leykin! Are you ready? Go answer.
- Hurrah! Recess!
- The lesson is starting!
- If there was no slide...
RESISTANCE FORCE OF SLIDE
- ...you would fall down like Newton's apple.
At the same time, the gravitational force
lets you overcome the frictional force of the slide surface
and descend along the inclined plane into the water.
- To make the parallelogram of forces clearer for you,
here is what we shall do:
Let's substitute the force of gravity with the force of wind pressure.
SAILS
WIND
TRACTION
HEADING HEAD TO WIND
HEADING CLOSE HAULED
PORT TACK
STARBOARD TACK
PORT TACK
HEADING STERN WIND
RECESS
- So, did you understood what I told you about the sail?
- What the frig do I need sails for?
BUOYANT FORCE
- I told you that the sail is more reliable!
- Some champion you are!
"On the isle of Little Cayman is buried a treasure".
- Oho!
- Enough physics! Let's learn some geography!
- Enough for today. We'll study geography next week.
