Position of Moving Particle
Consider a particle in xy-plane
moving along a curve AB. Let at any time 't', the particle is at point
'p' whose position vector is given by
(OP) ̅=
r ̅
Now as the time progress the particle
changes its position. It means that its position depends upon the time ‘t’ so
r ̅=r ̅(t)
r ̅=
t2i+6tj
Note:
r ̅=r ̅(t) is a function of
time, it is the equation of the locus(path) along with the particle
moves.
