I so care, but I don't know.
Motion is always relative to something. There's no such thing as really "stationary."Stationary only means that the motion of the observed object matches the observer's motion. Example: Reading the book that lies 'stationary' in your lap while you're in a car or on a passenger jet.
A reference point should be in a state of rest or constant motion in order to accurately determine the motion of other objects. This allows for easier comparison and observation of the movement of other objects relative to the reference point.
It means the motion you measure for something depends on where you measure from. For example, You are on the sidewalk and measure the speed of a truck and its driver to be 60mph. But if you were in the truck and measured the speed of the driver it would be zero, because now, relative to you, the driver is not moving.
Objects in motion have kinetic energy, which is the energy associated with their motion. This energy depends on the velocity and mass of the object.
Kinetic energy is the energy caused by the motion of an object.
Observation of an object at rest or stationary would not show molecular motion.
Probably an observation of nature.
Introspection is the self-reflective observation of one's own sensations and feeling.
relativity
An observation is something that can be seen with your own eyes, and an inference is something based on face. Therefore, an inference does not come before an observation, but rather after.
It depends on what aspect of motion is being graphed: the displacement, speed or acceleration.
The observation that liquids can flow and take the shape of their container supports the inference that liquids are composed of small particles in motion. This behavior suggests that the particles making up the liquid are moving and sliding past each other.
plane motion depends upon two types motion 1-Rectilinear motion 2-curvelinear motion (the angle remain same)
Depends on the subject. Could range from scientific observation to surveys.

curl is clear from observation that many fluid flows involvs rotational motion of the fluid particle.
mass for linear motion and in rotational motion it depends on the distribution of mass about the axis of rotation ................................................GhO$t
