Q1. In the absence of air and other resistances, a bird already in motion can continue to fly forward without the need to flap its wings.  Answer 'False' or 'True'. If 'False', you need not continue to answer this question. If 'True', what law can you associate it with? Q2. The high velocity gases discharged through the nozzle of an aircraft gas turbine engine produce an action force rearward. It is the reaction to this force that propels the aircraft forward. Answer 'False' or 'True'. If 'False', you need not continue to answer this question. If 'True', what law can you associate it with? Q3. Apply an appropriate Newton’s law, explain concisely how a propeller can produce the thrust to propel an aircraft forward.

Units and Dimensions

These are generally defined as the terms which precede or describes the dimensions further. These are also further divided into two parts namely fundamental units and the derived units.
