Question

The slope of the straight line connecting the points corresponding to $\left(v_2,t_2\right)$ and $\left(v_1,t_1\right)$ on a plot of velocity versus time gives

• A. average velocity
• B. average acceleration
• C. instantaneous velocity
• D. None of these

Answer 1

Answer: (B)

Average acceleration is defined as the average change of velocity per unit time. On a plot of $v-t$, the average acceleration is the slope of the straight line connecting the points corresponding to $\left(v_2,t_2\right)$ and $\left(v_1,t_1\right)$.
