Section 8.1.notebook November 17, 2019 Section 8.1 Vectors Objective: Add and subtract vectors geometrically. Find equal, opposite, and parallel vectors. Vector any quantity that has both magnitude(length) and amplitude(direction)(an angle made with the positive x axis). Ways to add/ subtract vectors: PARALLELOGRAM METHOD: TRIANGLE METHOD( TIP to TAIL): 1 Section 8.1.notebook November 17, 2019 Opposite Vectors same length. opposite direction Equal Vectors same length and same direction Parallel vectors same or opposite direction. Resultant vector the sum of 2 or more vectors. Each vector is made up of a vertical and horizontal component. 2 Section 8.1.notebook November 17, 2019 Scalar a physical quantity, such as speed, that is described by a single real number. (magnitude or size only) Difference with scalar and vector is that a vector has both magnitude and direction. zero(null) vector resultant when you add 2 opposite vectors. Creates equilibrium!!! 3
