## 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) Negative
• b) zero
• c) positive
• d) none of these

• c) positive

• a) One dimensional motion

## Q4 Displacement can be:

• 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:
