From the displacement-time graph of a cyclist given below in the Figure, find The displacement from the initial position at the end of 10 s,
Advertisements
उत्तर
Initial position = 0 m
Final position at the end of 10 s = -10m
Displacement = Final position - Initial position
= (-10) m - 0
= -10 m

Is displacement a scalar quantity?
A body is moving in a straight line and its displacement at various instants of time is given in the following table
| Time (s) | 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 |
| Displacement (m) | 2 | 6 | 12 | 12 | 12 | 18 | 22 | 24 |
Plot the displacement-time graph and calculate
(i) Total distance travelled in the interval 1 s to 5 s.
(ii) Average velocity in time interval 1 s to 5 s.
Copy the following table and fill in the blank spaces.
| Quantity | S.I. Unit | Scalar or Vector |
| Displacement | ___________ | ___________ |
Can you suggest the kind of motion of a body from the following distance – time graph?
Write the SI units for measurement of distance and displacement.
A particle moves along a circular path. How many times does it change its direction in two complete rounds?
Geetha takes 15 minutes from her house to reach her school on a bicycle. If the bicycle has a speed of 2 m/s, calculate the distance between her house and the school.
Using the following data, draw time - displacement graph for a moving object:
| Time (s) | 0 | 2 | 4 | 6 | 8 | 10 | 12 | 14 | 16 |
| Displacement (m) | 0 | 2 | 4 | 4 | 4 | 6 | 4 | 2 | 0 |
Use this graph to find average velocity for the first 4 s, for the next 4 s and for the last 6 s.
Assertion: If the displacement of the body is zero, the distance covered by it may not be zero.
Reason: Displacement is a vector & distance is a scalar quantity.
