Hi, my name is Stefan. Today, I'm going to be speaking on the Pythagorean Theorem in physics. Now here's what the Pythagorean Theorem is if you have a right triangle. It says that C squared = A squared + B squared. Now this helps us, let's say a car is traveling and it's going up some hill. If we know that the force pushing horizontally is 3 and the force pushing vertically is 4, we can find the slanted force that the car is being pushed with. So we can say that the force = the square root of 3 squared + 4 squared. So that = the square root of 9 + 16 which = 5 and there's a great way of how the Pythagorean Theorem is used in physics.
