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 average speed if you run 50 meters in 10 seconds.

Solution Step 1 of 2 The speed of the object is the rate of change of its position or speed is the ratio of distance travelled by time taken. It unit of measure if meter per second. That is Speed tells about; how many meters does the object has traveled in one second. It is given by, Speed(s) = Distance travel=ex Time taken t
