Q1 A boy starts from a point A, travels to a point B at a distance of 1.0 km and then returns to A. If he takes one hour to do so, his average velocity is
- a) 3 km/h
- b) 1.5 km/h
- c) 0
- d) 2 km/h
- c) 0 ( Boys starts from point A then return to point A therefore displacement is zero and hence velocity is Zero)

- a) positive
- b) negative
- c) zero
- d) all of these
- a) positive

- a) speed
Q6 Velocity of an object is given by:
- a) distance/time
- b) time/displacement
- c) displacement/time
- d) time/distance
- c) displacement/time
Q7 For a body in uniform motion the graph between displacement and time is a:
- a) curve
- b) triangular in shape
- c) rectangular in shape
- d) straight line
- d) straight line
Q8 For a velocity time graph a line parallel to x-axis represents:
- a) constant velocity
