Acceleration is a vector quantity, meaning it has both magnitude and direction.

The SI unit for acceleration is $\text{m/s}^2$.

If acceleration is constant, the velocity-time graph will be a straight line.

Uniform acceleration allows for predictable motion calculations.

Real-world motorcycle acceleration is rarely perfectly constant.

Analysis of traffic flow and road safety dynamics.

Initial velocity ($u$) = $10 \text{ m/s}$, Final velocity ($v$) = $30 \text{ m/s}$, Time ($t$) = $4 \text{ s}$. Calculation: $a = \frac{30 - 10}{4} = \frac{20}{4} = 5 \text{ m/s}^2$.

Option B ($10 \text{ m/s}^2$) is incorrect because the numerator $20$ divided by $4$ is $5$, not $10$.
