the blanks:
a The Change in position of an object with respect to time
is called ____________.
b ________________________ is the length of the path
actually traversed by a body.
c
______________________
is the shortest distance from initial to the final position of the body.
d
A
body moving on a circle of radius r comes back to the starting point after some
time. Its displacement is _____________________ but distance travelled is
_________________
e Displacement is ____________quantity and displacement is a
_________quantity.
f Speed is defined as the ___________ travelled by a body __________________
g For a body in non-uniform motion, its motion is described
in terms of________
___________ speed.
h Velocity is defined as ______________ travelled by a body
in a _________________
Direction per unit
__________________.
i Velocity has both___________________ and _________________
hence velocity is a
_______________quantity.

continuously due to
the
change in its _______________ or change in its ___________________
k Motion
is said to __________________ if the velocity is increasing with time.
l
Motion
is said to __________________ or _______________________if the velocity is
