Question

Q 4 ,5 . describe the motion represented by the displacement - time graph shown here
​

Answer 1

Answer: All the slopes show Veloocity

Explanation: (4) (a) Shows a uniform velocity, and the displacement increases at a constant per unit time

(b) Shows a Positive velocity till the mid-way, and slowly, the body comes to the initial position. Therefore, displacement = 0

5. (a) Shows non uniform velocity, where, the body starts to move at a greater speed, then comes back, ten moves forward, and then comes back to the initial position. Therefore, displacement = 0

(b) The graph is plotted incorrectly
