Тело переместилось из точки 1 с координатами x1=-1 см и y1=2 см в точку 2 с координатами x2=-1 см и y2=-1 см, а затем из точки 2 с координатами x2=-1 см и y2=-1, в точку 3 с координатами x3=3 см и у3=-1 см. Чему равны его путь и модуль перемещения?
The distance moved by the body can be calculated by finding the displacement between points 1 and 3, which is equal to the hypotenuse of a right triangle formed by connecting point 1 and 3. Using the Pythagorean theorem, we can find that the distance moved is √((3-(-1))²+(-1-2)²)= √(16+9)= √25 = 5 cm. As for the displacement, it is simply the magnitude of the body's final position vector, which is also equal to the distance moved. Therefore, the displacement is also 5 cm.Note: It is important to understand the difference between distance and displacement. Distance is the total length covered while displacement is the straight line distance between the initial and final position.
