2. Refers to the change in velocity with respect to
time, it is also a Vector Quantity
Formula = Acceleration = Velocity/Time =
Vi – Vf/T
3. A car accelerates from rest to a speed of 36
km/h in 20 seconds. What is the
acceleration of the car in m/s2?
Solution = convert 36 km/h into m/s, 36
km/h = 36 * 1000 m / 3600 s = 10 m/s
= 10m/s
10 m/s x 20 seconds = 0.5 m/s²
