How do you run on a slope?

Suppose you are riding a bicycle on a hilly road. From the running race activity, you know that to predict the nature of motion we need to record the distance covered by an object in shorter and equal time intervals.

                                




For a bicycle on a real road, it will be difficult to record data – there will be other people and vehicles on the road, it will be difficult to find the right place to sit and spot the cycle, etc.  

In that case, there is a need to design an experiment, that recreates the same event in your classroom. Using this, you can observe some parameters of the event and make a close guess about the real life event.
 

This in general is called a control experiment or a model of a real life situation.
