Instruction: The table given below shows distance (in cm) travelled by the bodies A, B and C. Read this data carefully and answer the questions which follow.
Distance (in cm) covered by different bodies
1. Which of the bodies is moving with
(a) constant speed?
(b) constant acceleration?
2. Which of the bodies covers
(a) maximum distance in 3rd second?
(b) minimum distance in 3rd second?
3. Which of the bodies is moving with non-uniform acceleration?
1. a) Body A moves with constant speed since it travels equal distance in equal interval of time.
b) Body B moves with constant acceleration since the rate of change of distance per second in it is constant.
2. a) Body C covers the maximum distance in 3rd second.
C covers 100 cm whereas A & B cover 20 cm & 24 cm in 3rd second.
b) Body A covers the minimum distance in 3rd second.
Since A covers only 20 cm which is less than covered by B (24 cm) and C (100 cm)
3. Body C is moving with non-uniform acceleration.
