In some movements, the trajectory of a body can be clearly seen even in retrospect. Skates and skis leave tracks in the ice or snow that trace the paths of the skaters. In sand, too, the tracks can be used to identify the paths of vehicles - buy assignment online , people or animals. Condensation trails in the sky show the paths of airplanes, water trails on window panes show those of raindrops. Often, the orbit of a body, e.g. a satellite, can only be determined by complex measurements and calculations.
Movements can be classified according to the shape of their orbit (orbit shape). Mostly one distinguishes:
- rectilinear movements and
- curvilinear movements.
In a rectilinear motion, a body moves on a straight path. This is the case, for example, with a train moving along a straight track.
In a curvilinear motion, the body moves along any curvilinear path. This is often the case, for example, with a soccer player.
A special curvilinear motion is circular motion - do my engineering homework , in which a body moves along a circular path (orbit). An example of this is the gondolas of a Ferris wheel. To be distinguished from circular motion is the rotational motion of a body about an axis. For example, in a Ferris wheel, each gondola and the people in it perform a circular motion. The Ferris wheel as a whole rotates around an axis and thus performs a rotary motion.
When a body oscillates, for example in a swing or a clock pendulum, the body moves back and forth between two points. In this case, the path is part of a circular path. There are also oscillations that run along a straight line. This is the case, for example, with a vertical or horizontal spring oscillator.
