Lesson 1: Vectors – Fundamentals in addition to Operations Vectors in addition to Direction Vector Addition Resultants Vector Components Vector Resolution Component Method of Vector Addition Relative Velocity in addition to Riverboat Problems Independence of Perpendicular Components of Motion Vectors in addition to Direction All quantities can by divided into two categories – vectors in addition to scalars. A vector quantity is fully described by both magnitude in addition to direction. A scalar quantity is fully described by its magnitude. Examples of vector include displacement, velocity, acceleration, in addition to as long as ce. Each of these quantities dem in addition to s both a magnitude in addition to a direction are listed Vector quantities are often represented by scaled vector diagrams. There are several characteristics of this diagram that make it an appropriately drawn vector diagram. a scale is clearly listed a vector arrow (with arrowhead) is drawn in a specified direction. The vector arrow has a head in addition to a tail. the magnitude in addition to direction of the vector is clearly labeled. In this case, the diagram shows the magnitude is 20 m in addition to the direction is (30 degrees West of North).

Conventions as long as Describing Directions of Vectors The direction of a vector is often expressed as an angle of rotation of the vector about its “tail” from east, west, north, or south. The direction of a vector is often expressed as a counterclockwise angle of rotation of the vector about its “tail” from due East. Representing the Magnitude of a Vector The magnitude of a vector in a scaled vector diagram is depicted by the length of the arrow. The arrow is drawn a precise length in accordance with a chosen scale. practice Determine the magnitudes in addition to directions of vectors

Vector Addition Two vectors can be added together to determine the result (or resultant). The two methods used throughout the entire unit are: the Pythagorean theorem in addition to trigonometric methods the head-to-tail method using a scaled vector diagram The Pythagorean Theorem Example: Eric leaves the base camp in addition to hikes 11 km, north in addition to then hikes 11 km east. Determine Eric’s resulting displacement. The procedure is restricted to the addition of two vectors that make right angles to each other.

Using Trigonometry to Determine a Vector’s Direction Example: Eric leaves the base camp in addition to hikes 11 km, north in addition to then hikes 11 km east. Determine Eric’s overall resulting displacement. Note: The measure of an angle as determined through use of SOH CAH TOA is not always the direction of the vector.

Use of Scaled Vector Diagrams to Determine a Resultant The magnitude in addition to direction of the sum of two or more vectors can also be determined by use of an accurately drawn scaled vector diagram. Using a scaled diagram, the head-to-tail method is employed to determine the vector sum or resultant. applying the head-to-tail method to determine the sum of two or more vectors: Choose a scale in addition to indicate it on a sheet of paper. The best choice of scale is one that will result in a diagram that is as large as possible, yet fits on the sheet of paper. Pick a starting location in addition to draw the first vector to scale in the indicated direction. Label the magnitude in addition to direction of the scale on the diagram (e.g., SCALE: 1 cm = 20 m). Starting from where the head of the first vector ends, draw the second vector to scale in the indicated direction. Label the magnitude in addition to direction of this vector on the diagram. Repeat steps 2 in addition to 3 as long as all vectors that are to be added Draw the resultant from the tail of the first vector to the head of the last vector. Label this vector as Resultant or simply R. Using a ruler, measure the length of the resultant in addition to determine its magnitude by converting to real units using the scale (4.4 cm x 20 m/1 cm = 88 m). Measure the direction of the resultant using the counterclockwise convention. Note: the order in which three vectors are added has no affect upon either the magnitude or the direction of the resultant. The resultant will still have the same magnitude in addition to direction.

Resultants The resultant is the vector sum of two or more vectors. It is the result of adding two or more vectors together. practice Vector addition head in addition to tail method 10/20 do now What is the magnitude of the as long as ce needed to keep a 60.-newton rubber block moving across level, dry asphalt in a straight line at a constant speed of 2.0 meters per second
