A quantitv which can be represented completely by magnitude alone is called a vector quantity.
A girl walks along a straight path to drop a letter in the letterbox and comes back to her initial position. Her displacement-time graph is shown in Fig. Plot a velocity - time graph for the same.
An object starting from rest travels $20\, m$ in first $2\,\sec $ and $160\, m$ in next $4\,\sec $. What will be the velocity after $7\,\sec $ from the start ?
If the displacement$-$time graph for a particle is parallel to time axis, what is the velocity of the particle ?
Area under a $v -t$ graph represents a physical quantity which has the unit
