Examples of low friction in everyday life
WebFrom the fundamental equations of dynamics, we know that: V2 = u2 + 2gs. And for u=0 ,g=9.8ms -2 ,and s=4000 m,let us say,the drop would gain a velocity of: V 2 = 2 … Web[BL] [OL] [AL] Discuss examples of Newton’s first law seen in everyday life. [BL] [OL] [AL] Talk about different pairs of surfaces and how each exhibits different levels of friction. Ask students to give examples of smooth and rough surfaces. Ask them where friction may be useful and where it may be undesirable.

Let us take the example of static friction in which it looks like newton’s third law is not followed. When we push a heavy object say a rock, nothing happens. WebEnergy would be conserved: Without friction, energy would be conserved, and objects would continue to move perpetually without losing energy. Overall, the absence of gravity and friction would result in a very different physical universe than the one we observe today. 17. t Learning Task 2: List the things that might happen if there is no gravity.
