Give 2-3 examples of body position relative to different reference bodies.

Examples of body position relative to various reference bodies:

1) The boy, moving in a straight line towards the school located at a distance of 900 meters from the house, having walked 200 meters, decided to go to the store located along the way. If to describe the boy’s movement as a reference body, choose a house and place the origin of the coordinate line there, then the boy’s coordinate will be 200 m; if the store, then the coordinate will be 0 m, if the school, then 900 – 200 = 700 (m).

2) Similarly, the bus, moving from the city of Simferopol to the city of Evpatoria, the distance between which is 72.4 km, stopped in the city of Saki, having traveled 52.1 km. For the reference body for describing the movement of the bus, you can take the bus station in the city of Simferopol, in the city of Evpatoria, in the city of Saki.

3) The train left the city of Moscow for the city of Kazan, the distance between which is 815.8 km, making a stop in the city of Nizhny Novgorod after 416.9 km. For the reference body for describing the movement of the train, you can take the station in the city of Moscow, in the city of Kazan, in the city of Nizhny Novgorod.
