Explain the following concept in your own words with everyday examples:
Distance

उत्तर
It is the actual path length covered by an object during its motion. It is a scalar quantity.
For example, when we go to a mall for shopping from our house and then return to the house, the distance travelled by us would be twice the distance between our house and the mall.

Is displacement a scalar quantity ?
In which of the following cases of motion, the distance moved and the magnitude of displacement are equal?
If the displacement of an object is proportional to the square of time, then the object is moving with :
Define Displacement.
Give an example of a body which covers a certain distance, but its displacement is zero.
An object is thrown vertically upwards. It rises upto a height H and then returns to its initial position. Calculate
The displacement of the object.
The table below shows the distance travelled by two vehicles A and B during each second:
| Time (s) | 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 |
| Distance travelled by A (m) | 0 | 20 | 80 | 180 | 240 | 300 | 360 | 420 |
| Distance travelled by B (m) | 0 | 10 | 40 | 90 | 160 | 250 | 360 | 490 |
Which vehicle is ahead at the end of 7th second and by how much?
Four cars A, B, C, and D are moving on a levelled road. Their distance versus time graphs are shown in Fig. 8.2. Choose the correct statement.
A car starts from rest and moves along the x-axis with constant acceleration 5 ms–2 for 8 seconds. If it then continues with constant velocity, what distance will the car cover in 12 seconds since it started from the rest?
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.
