The document contains a 9th class physics test with multiple choice and fill-in-the-blank questions on topics related to motion including distance, displacement, speed, velocity, uniform and non-uniform motion. It tests definitions of rest, calculations of speed in km/h to m/s, finding distance between places given time and speed, and relationships between displacement, distance, speed, and velocity. There are also questions about an ant's displacement, train speeds, straight and curved path distances, and identifying graphs of distance-time and velocity-time relationships.

the two cities.
4) Fill in the blanks: -------------------- is a fixed point with respect of which a body is at ------------- or in -------------- .
5) What is velocity in terms of speed?
Section-2 (Answer any three questions) 3x2=6m
6) An ant travels a distance of 8 cm from P to Q and then moves a distance of 6 cm at right angles to PQ. Find its
resultant displacement.
7) The train ‘A’ travelled a distance of 120 km in 3 hours whereas another train travelled a distance of 180 km in 4
hours. Which train travelled faster?
8).Which of the following is true for displacement? (a) It cannot be zero. (b) Its magnitude is greater than
the distance travelled by the object.
9) Suppose that you run along three different paths from location A to location B. Along which path(s) would
your distance travelled be different than your displacement?
