Using Newton's 3rd law, explain how you could protect something that you know could collide with something else (like your phone, or a car). (THIS QUESTION WILL SHOW UP ON THE TEST)

What is - you could provide a soft bumper of some sort, or a crumple zone (something that will crunch and take the brunt of the force before it hits your phone or car or object), or you could add a spontaneous air bag device.
