Question

Motion of cyclist on straight leveled Road

Answer 1

Motion of a body is always determined with the

help of a reference point. The chosen reference

point is considered to be fixed in ideal notion

so that the change in position of a body can be

observed. A reference point in motion may also

be chosen but in this case the velocity of the

body and the reference point must not be equal

otherwise the change in position of the body

cannot be observed.
