SUMMARY

Newton's Third Law states that for every action, there is an equal and opposite reaction, which applies to the scenario of a bike crashing into a metal fence. The discussion highlights that while the forces exerted by the bike and the fence are equal in magnitude, the differing masses and material properties of the two objects result in different effects. The bike, having greater mass, exerts a more significant impact on the fence, causing it to bend. Understanding material strength and mass is crucial in analyzing the outcomes of such collisions.

Homework Statement


When a bike crashes into a metal fence why does the fence bend when the magnitude of the forces that they exert upon each other are the same?


Homework Equations



FAB = -FAB

The Attempt at a Solution



I think this is because the bike has more mass than the fence... but i am not sure how this is applied.
 
Physics news on Phys.org
no f=ma so the mass is already accounted for, should certain materials or apparatuses be able to withstand more force than others?
 
and you also have to remember that the opposite forces work on different bodies
