These are “plug-in-the-number” type activities to familiarize yon with the equations that link the concepts of physics. They are mainly one-step substitutions and are less challenging than the Problem. ? Calculate the acceleration of a car (in km/h·s) that can go from rest to 100 km/h in 10 s.

Solution 10PC Introduction Acceleration of an object is the rate of change of velocity. If there is no change in velocity, the acceleration will be zero. Step 1 The equation for acceleration is, a = change in velocity / time taken Or, = (v-u) / t Where, v - final velocity u...
