The answer is relative motion.
The change in position of an object compared to a reference point(another object) is called motion.
The change in position of one object compared to another object is called relative motion. This describes the movement of one object relative to the other, taking into account their positions and velocities.
The change in one object's position compared to another object's fixed position is known as relative position. It describes the displacement or distance between the two objects at a specific point in time. By measuring the relative position, you can determine how much one object has moved in relation to the other.
Sure, if one object presses down on another object.
The change in size of an image compared with the size of an object is termed magnification. This can be calculated as the ratio of the size of the image to the size of the object. Magnification can be expressed as magnification = image size / object size.
Change of position relative to another object
Actually, a change in the position of an object when compared to a reference point is defined as displacement. Speed, on the other hand, is the rate at which an object covers distance over a period of time.
Displacement is the term used to describe the change in position of an object when compared to a reference point. It is a vector quantity that includes both the distance and the direction of the movement.
When an object's distance from another object is changing, it is in motion. The change in distance indicates that the object is moving relative to the other object.
Measuring how heavy an object is compared to another object.
Wanted and unwanted outer forces will always change the velocity of an object.
When you look at something else, your attention changes form one object to another.
