That's completely true. The only thing I can measure is how fast an object
is moving past me.
If you come along and ask me "But how fast was it reallymoving ?", that's
a meaningless question. There's no such thing as 'real' motion, only motion
compared to something.
Notice that there's actually no such thing as "at rest", or "motionless".
If I measure the speed of something and it turns out to be zero, then
that only means that the object and I are both moving at the same speed
and in the same direction.
Example ? Sure. How about the book in your lap, that you were reading
until you drifted off in your comfortable reclining seat, on a passenger jet
that I observe to be 5 miles above the ground moving at 350 miles an hour.
What else can I help you with?
What is the definition of the word relative motion?
Relative motion is the concept that the motion of all objects is relative to other objects. If you are sitting still right now you are not moving relative to the earth, however you are moving relative to sun.
What is location of an observer of motion?
The location of an observer of motion is typically described in terms of a reference frame. This frame can be stationary or in motion itself, and serves as a point of reference to describe the position and movement of objects. Observers can be located at any point within this reference frame to study the motion of other objects relative to their own position.
What is a force that resist the motion relative to each other for objects that are touching?
Friction is the force that resists the motion of objects relative to each other when they are in contact. It arises due to the microscopic roughness of surfaces coming into contact, creating resistance to sliding or rolling motion.
What is a change in an object's position as compared to objects around it?
A change in an object's position relative to other objects is called motion. It refers to the movement of an object through space and can be described in terms of distance, speed, and direction. Motion can be linear, circular, or oscillatory depending on the path followed by the object.
When an object 's distance from another object is changing?
The objects are in motion relative to each other.

Who proposed the concept all motion is relative?
The concept that all motion is relative was proposed by Galileo Galilei in the 16th century. He developed the idea that there is no absolute motion but rather motion is only perceivable in relation to other objects.
What is the function of static reference frame?
A static reference frame serves as a fixed point of reference in which the position or motion of other objects can be measured or described. It provides a stable framework for analyzing the relative positions and velocities of objects in motion. This is commonly used in physics and engineering to simplify the analysis of complex systems.
How do you know if something has motion?
You measure the distance from the object to some other object several times and if there is a difference, the objects are in motion to each other. There is no absolute frame of reference in the Universe (according to Einstein).
What is the electric force between objects that are not in motion called?
The electric force between objects that are not in motion is called the electrostatic force. This force is responsible for the attraction or repulsion between charged objects that are at rest relative to each other.
What is relative acceleration?
Relative acceleration refers to the difference in acceleration between two objects that are in motion relative to each other. It measures how their acceleration vectors are changing with respect to each other as they move. This concept is often used in the study of dynamics and motion in physics.
What is the resistance to motion created by two objects moving against each other?
The resistance to motion created by two objects moving against each other is called friction. Friction occurs when the surfaces of the two objects come into contact and oppose the relative motion between them, causing heat and wear.
All motion is relative to what?
All motion is relative to yourself, as there is no fixed point anywhere in our universe, as it is all traveling away from the center of the big bang. But if we ever find where the bigbang happened, that would be where all motion is relative to
