The (x -t) graph of a moving particle is shown in the figure below. Comment on the signs of the velocities at the points C,D,E and F. |
|
Answer» The slope of the tangent of (x -t) graph at a point gives the velocity of the body at the point. (i) At C, the velocity is + ve. The tangent to the (x -t) graph at C makes an acute angle with the time axis. Therefore, the shape and hence velocity is + ve. (ii) At D, the velocity is zero. (iii) At E, the velocity is -ve. (iv) At F, the velocity is +ve. |
