What do we mean when we say that motion is relative? Give an example to support your answer.
Answers
Answer:
motion as observed from or referred to some material system constituting a frame of reference
Explanation:
the motion of one body with respect to another regarded as fixed compare relative velocity.
for better illustration :
when we are having two bodies and we are relating the motion of one body with another
Example:
the best example for this motion is friction
friction means the relative motion which oppose the force between two bodies when they are in contact
hear the two bodies are performing motion but in opposit direction hear we are we took direction as the refrance
which made it a relative motion
Motion of a body, as perceived by an observer is the resultant effect of the states of motion of both the observer and the body. When one says that a body is in rest on Earth, it is in rest relative to us, on the Earth. Actually both the body and the observer are in motion, since the Earth rotates about an axis, and also revolves around the Sun. So, from the perspective of an astronaut on a spaceship, both the observer and the body are moving along with the Earth. There is no absolute rest or motion.
