Practice A plane flies 1500 miles East and 200 miles South What is the magnitude and direction of the planes final displacement A hiker walks 80 m North 20 m East 50 m South and 30 m West What is the magnitude and direction of the hikers displacement. Physics 6A. Prepared by Vince Zaccone. For Campus Learning Assistance Services at UCSB. A . VECTOR. describes anything that has both a . MAGNITUDE. and a . DIRECTION. The MAGNITUDE describes the size of the vector.. The direction of a headwind is into the . front. . of . the plane. . So a headwind the will cause the plane . to slow down.. . A tailwind blows from behind the plane. It blows into the back, or . tail, . A jogger runs 145m in a direction 20.0 degrees east of north (vector A), and then runs 105m in a direction 35.0 degrees south of east (vector B). Using components, determine the magnitude and direction of the resultant vector C for these two displacements.. Describing the Motion of Objects. Distance (. d. ): . The total length of the path travelled by an object. Measured in meters (m). Describing the Motion of Objects. Direction: . The line an object moves along from a particular point. We have already discussed finding the magnitude of vectors in various forms. Especially, in component form. But, sometimes we may have to go the other way around. Given a magnitude, find the components. AND . SCALAR. QUANTITIES. Vector. : A quantity that has both magnitude and direction.. Scalar. :. A quantity which can be described by magnitude only(. NO. direction). Magnitude. :. The size of a quantity(number). . Vectors. . . . When an object moves along a straight line, its velocity can be determined by a single number that represents both magnitude and direction. (forward if positive and backward if negative.. Objectives:. To describe vectors. To solve problems that involve vector addition. Vector. : .  . Any quantity with magnitude (size) and direction. . Magnitude. : . The . distance. from the initial point to the terminal point.. The line and arrow used in Ch.3 showing magnitude and direction is known as the . Graphical Representation. Used when drawing vector diagrams. When using printed materials, it is known as . Algebraic Representation. Distance. Distance. (d) – how far an object . travels. Does . not. depend on . direction. Imagine an ant crawling along a . ruler. What distance did the ant travel?. d . = 3 cm. cm. 0. 1. 2. 3. 4. Distance vs Displacement. Distance – the total amount traveled.. Displacement – the total amount displaced from the starting point.. Solving Problems. Organize the Information. Sketch the scene. Verify Units. Read Chapter 1.6-1.9. Scalars and Vectors. All measurements are considered to be quantities. In physics, there are 2 types of quantities – . SCALARS. . AND . VECTORS. .. Scalar. quantities have only magnitude.. Warmup What is the magnitude and direction of the gravity of the Earth? Solve this problem: If the initial velocity of a ball is 12.6 m/s when it is thrown upward from a height of 2.3 m, what is the velocity of the ball when it passes this point on the way down? Distance and Displacement. Learning Objectives. I can describe the difference between scalar and vector quantities.. I can determine displacement and distance using a scale diagram or calculation.. I can calculate the displacement of an object with two vector quantities in one direction or at right angles..
