If you’re interesting in studying the terminal velocity, you should understand that it’s reached when the air resistance force that is pushed up against any falling object is equal to the gravity force that pushes this object downward. When it falls down, downward, there is a certain drag force that works by impeding a motion. Besides, it acts not only in the direct that is opposite to this motion, but it also depends on the square of the object’s speed.
When a given object starts falling, its speed is quite slow, and this means that its drag force is also small. As it keeps increasing its speed, the same thing happens with its drag force. This is how its speed increases to the point where its drag force acts to cancel out this kind of force because of gravity. This means that an object no longer accelerates so that its speed remains constant. Keep in mind that the drag force is something that makes it slow down as it keeps moving downward. Otherwise, it would keep increasing its speed as it got closer and closer to the ground.
Another interesting thing that you should understand is that different things have their different terminal speed. When it comes to the terminal velocity, it’s not only based on their speed, but it also depends on the density of fluids through which given objects are moving. Remember that Joe Kittinger was the first one who reached the terminal velocity in 1960. It’s advisable to learn more about this subject to understand why it’s better to jump out of planes with parachutes than without them.
As objects fall, the gravity force causes them to speed up on an ongoing basis, and this important concept was predicted by Newton. As objects get faster and faster, the drag force of the air keeps increasing until it equals the gravity force so that there isn’t any net force that acts on given objects. When all of these forces are well-balanced, they will no longer slow down or speed up, but they will keep falling at their terminal or constant velocity.
In conclusion, you shouldn’t forget that the drag force always depends on the shape and size of objects. This means that they have their lower terminal velocity if their surface area is quite large. Another important fact is that their weight also affects the drag force and terminal velocity. You need to understand these basic concepts when getting more information about this subject if you want to get better grades and use them in your real life.
