Lesson 1: Intro to Vectors

• a scalar is a quantity with only a magnitude
• a vector is a quantity with a magnitude and a direction
• types of notations that vectors can be represented with: standard notation, true bearing, quadrant bearing
• a vector can be drawn as a ray, the arrow being the head and the starting point being the tail
• free vectors have no fixed position, so they can be placed anywhere as long as the magnitude and the direction are still the same
• Parallel vectors: vectors that have the same or opposite direction, but not always the same magnitude, since they are free vectors, they could possibly be on top of each other
• Equivalent vectors: vectors that have the same magnitude and direction, location of vectors does not matter
• Opposite vectors: vectors that have the same magnitude but opposite direction
