1.4 Vectors | General Physics

Chad provides a comprehensive lesson on everything related to Vectors and the role they play in Physics. He begins with a trigonometry review covering the trigonometric identities commonly used in working with vectors. He then defines a vector and explains the difference between a scalar vs vector quantity. He then shows exactly how to split vectors down into x and y components explaining the standard of using the angle with respect to the x-axis. Finally, Chad demonstrates how to add two vectors together as follows: 1. Splitting vectors into components 2. Adding the x and y components together separately 3. Combining the x and y components using the Pythagorean theorem to find the magnitude of the resultant vector 4. Using the tangent identity to calculate the direction (angle) of the resultant vector 00:00 Lesson Introduction 00:56 Trigonometry Review 08:49 Scalar vs Vector Quantity 12:44 How to Split a Vector into X and Y Components 29:02 How to Find the Magnitude of the Resultant Vector (How to Add Vectors) 36:49 How to Find the Resultant Vector Angle (i.e. Direction) Check out Chad's General Physics Master Course: https://www.chadsprep.com/physics-you...
