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 your-walking speed when you step 1 meter in 0.5 second.

Solution 1PC Step 1 : We have a formula to calculate speed as speed = distance time Considering the data given Distance - 1 m Time - 0.5 s We need to calculate speed Substituting the values we get speed = 1 m 0.5 s speed = 2 m/s Thus the speed is obtained as 2 m/s
