My Favorite Physical Force


The Centripetal force is not one that I 100% understand, but i do think it is one of the more useful ones in the world to somewhat understand.

Physics was by far my favorite subject in High School, although, I didn't really excel in it, I still found everything we learned to be very interesting. It helped understand the motion of things and how the world really operates.

So what does F(Centripetal) equal to... well its m * ( V^2/r). What does it mean, well.. any motion in a curved path represents accelerated motion and requires a force toward the center of the curvature. This is the center seeking force.

How can you apply it to everyday life... in your car, when driving on a curved road, before going into the turn, all your velocity is going straight. The mistake most people make is they break, and the velocity/motion of the car continues to go straight. The key thing to do in a turn is accelerate, so that the acceleration of your car is pointed in the new direction. This is the key to driving and mostly race car driving that most people don't understand. And I digress.
