Is there a difference between the force exerted by a compressed spring and the force exerted by the same poles of two magnets when they come near each other?
Sometimes, we will not provide you with a clear answer to the question that we have framed for the reason that we want you to take this question in your mind and talk with your friends, ask your teachers and search online for its answer. This is one of those questions:
A compressed spring
You most probably have come across a spring in your life. They are an essential part of many mechanical devices. And you must have probably played with it, given that you are a curious human being. When you had a spring in your hands, you pressed it from both its ends or you pulled it apart from those two ends. You also perhaps bent the spring creating a U or O. Fun to play right?
When you pressed the two ends of the spring, you compressed that spring by definition. And you must have felt a force on your fingers from both the ends. We want you to think of this force. We highly advise you get a spring right now and play with it. Compress it. Take a note of this force.
Same poles of two magnets
Now, you must also have played with magnets and metal stuff. But have you ever gotten your hands on two pairs of magnets? If not, get two magnets now.
As you know, magnets have two poles that we call South and North poles. When you are playing with them now, you don’t have to know which pole is which. Just bring your two magnets closer and closer and if the poles are opposite they will attract each other more and stick to each other, or they will repel each other if the poles are same.
Let’s focus on this force of repulsion between two same poles of two magnets.
Compare the forces given by a compressed spring and the two repelling magnets. Now granted that the force in the first case is just in one object, spring. And the force in the second case is between two objects, our magnets. But in both the cases, your hands or fingers are being pushed away by the spring and the two magnets.
Are they similar?
Now, what we want you to do is, play around, and study if these two forces are similar (or the same). And if yes, frame an explanation around your reasons and email it to us at email@example.com. If no, again, frame an explanation around your reasons and email it to us at firstname.lastname@example.org.
Extra trippy question:
Now, think of the time when you were in a car or a bus and that vehicle took a turn. You felt a force that pushed you in the direction opposite to the turn, right? What kind of force is this? Is this also similar to the above two forces that we compared?
