. In which of the following cases of motions, the distance moved and the
magnitude of displacement are equal?
(a) If the car is moving on straight road
(b) If the car is moving in circular path
(c) The pendulum is moving to and fro
(d) The earth is revolving around the Sun
Slope of a velocity – time graph gives
(a) the distance
(b) the displacement
(c) the acceleration
(d) the speed
Suppose a boy is enjoying a ride on a merry-go-round which is moving
with a constant speed of 10 m s–1. It implies that the boy is
(a) at rest
(b) moving with no acceleration
(c) in accelerated motion
(d) moving with uniform velocity
If the displacement of an object is proportional to square of time, then the
object moves with
(a) uniform velocity
(b) uniform acceleration
(c) increasing acceleration
(d) decreasing acceleration
The numerical ratio of displacement to distance for a moving object is
(a) always less than 1
(b) always equal to 1
(c) always more than 1
(d) equal or less than 1
A particle is moving in a circular path of radius r. The displacement after
half a circle would be:
(a) Zero
(b) π r
(c) 2 r
(d) 2π r
