Example 1

easy
A car accelerates from 10 m/s10 \text{ m/s} to 30 m/s30 \text{ m/s} in 5 s5 \text{ s}. What is the acceleration?

Solution

  1. 1
    Use the acceleration formula: a=ΔvΔta = \frac{\Delta v}{\Delta t}.
  2. 2
    Substitute the initial and final velocities: a=30−105a = \frac{30 - 10}{5}.
  3. 3
    a=205=4 m/s2a = \frac{20}{5} = 4 \text{ m/s}^2

Answer

a=4 m/s2a = 4 \text{ m/s}^2
Acceleration is the rate of change of velocity. A positive acceleration means the object is speeding up in the positive direction.

About Acceleration

The rate at which an object's velocity changes over time, measured in metres per second squared (m/s²).
