How can you find the following?
$(i)$ Velocity from a displacement-time graph.
$(ii)$ Acceleration from a velocity-time graph.
$(iii)$ Displacement from a velocity-time graph.
$(iv)$ Velocity from an acceleration-time graph.

(N/A) $(i)$ By finding the slope of the displacement-time graph, where $v = \frac{\Delta \text{displacement}}{\Delta \text{time}}$.
$(ii)$ By finding the slope of the velocity-time graph, where $a = \frac{\Delta \text{velocity}}{\Delta \text{time}}$.
$(iii)$ By finding the area under the velocity-time graph, where $\text{Displacement} = \text{Area under } v-t \text{ graph}$.
$(iv)$ By finding the area under the acceleration-time graph, where $\Delta v = \text{Area under } a-t \text{ graph}$.
