1 Objective To learn how to add vectors graphically and component method and compare with expected resultant vector. Equipment 1. protractor 2. ruler 3. paper 4. force table 5. set of masses 6. triple-beam balance Theory DEF : A vector is a quantity that has both magnitude and direction. DEF : A scalar is a quantity that has magnitude but NO direction. Ex. Vectors Ex. Scalars Force Temperature V e l o c i t y T i m e Displacement Mass Momentum Speed Vector Notation A – Boldface letters A G - Arrow above letter A – Magnitude of vector A A vector is defined graphically by an arrow whose length is proportional to the magnitude of the vector quantity. The direction of the arrow points in the direction of the vector quantity. Adding Vectors Graphically Consider adding two vectors A and B graphically. The two vectors are shown below. q q A B A B R f 1. Select an appropriate scale. (Ex. 20 cm = 5 N) 2. Draw vector A to scale and in the proper direction.
