What is the phenomenon of a car's body movement when driving on a straight road?

When a car is driving on a straight road, the movement of its body is a translational phenomenon. The car moving forward on the road is an overall movement in one direction, which, according to the concept of translation, is a translational phenomenon. The rotation of a fan's blades around a central axis, based on the concept of rotation, is a rotational phenomenon. Examples of translational and rotational phenomena are as follows: 1. Translational phenomena: Elevators moving up and down, flags on flagpoles, light rail trains moving on straight tracks, conveyor belts, cars moving on straight roads where the entire vehicle is translating, items on conveyor belts, etc. 2. Rotational phenomena: Windmills, screwing in screws, merry-go-rounds, revolving doors, swinging on swings, etc.
When driving on a straight highway, the car body basically moves forward at a constant speed. The front of the car is aligned with the road, the tires roll smoothly, and the engine power propels the body in a straight glide. However, the road may not be perfectly flat, and small potholes or bumps can cause slight vibrations in the body, but the suspension system absorbs most of the impact, making the entire car glide as smoothly as ice skating. I often drive on highways, and in this state, the car's posture remains stable. Wind resistance can affect the movement, but as long as there is no sudden acceleration or braking, the direction of movement remains unchanged. Remember, during long-distance trips, regularly checking tire wear can reduce unnecessary body sway and ensure safe driving.
