Engineering Crash Cushions to Learn Newton's Third Law
Newton's Third Law Example
Car crashes are a dangerous example of Newton's Third Law. The car exerts a large force on the wall and the wall then exerts a large force back onto the car. Civil engineers are always trying to think of new ways to make highways safer. Building crash cushions along highways that reduce the impact force of the collision will, according to Newton's Third Law, also reduce force experienced by the passengers of the car. This can save lives.
