Unit 5 Post - 6/28: Ukerub It Up!

Directions, magnitudes, and angles... OH MY! The "Ukerub" technique is all about thaking 2 vectors and getting one resulting one from which you can find the total displacement and angle of a "journey". First you define each of your given vectors in x and y terms (which may require the use of trigonometry functions), then add them together to find the resultant vectors in where you use opposite SOHCAHTOA to find the angle and Pythagorean Theorem to find your variables!

When learning about Newton's laws we learned about inertia and friction. Inertia is an objects ability to stay in the same state of movement that it's in. Friction is a type of force that works against motion and impending motion. In this video, I represent an object moving at a low and constant velocity with no acceleration. The only forces acting on me at that time are my weight downward and "normal" upward with equal force. My inertia is high because, although my velocity is low, I can maintain it easily. My friend Sam represents friction; with the support of the table, her mass is greater than my mass, so when come in contact I can no longer move. The force of her friction is greater than the force of the velocity I'm moving at or my force of inertia.
