1. Roadside trees appear to move backward for passengers in a moving bus because their relative motion is perceived in relation to the bus. As the bus moves forward, objects outside it seem to move backward.

  2. We don't directly perceive the motion of the Earth because we are in constant motion along with it. Our sensory systems adapt to this motion, making it imperceptible. Additionally, the Earth's rotational and orbital speeds are relatively constant, further diminishing our perception of motion.

  3. Yes, the motion of the Earth is responsible for phenomena such as day and night, the apparent motion of celestial bodies, and the Coriolis effect, among others, due to its rotation and orbit.

  4. We perceive some objects in motion when their relative position changes over time, while others appear at rest when their position remains relatively constant relative to our reference frame or observation point.

  5. The motion along a straight line in the example can be described as consisting of distinct segments (OA, AC, CB), with the object moving forward and backward along this line.
