PPT-Vectors: Position and Displacement

Lesson 11 February 2 nd 2011 If a student said that they had to walk 800m to get to school today you would only know the distance they travelled and the destination You would not know their starting point or the directions they took to get here. Scalar quantities . have only a magnitude (amount).. Vector quantities . have a magnitude . and. a direction. . We represent them as . arrows. .. Distance. (d): . the . separation between . two . points. . Brown & Wilson’s Definition:. Two . closely related . species have overlapping ranges. In the parts of the ranges where one species occurs alone, the populations of that . species . are similar to the other species and may even be very . Interferometric. Radar System. NJ Route 23 Bridge - Structure No. 1618-150. Over US 202, Ramps M & N and Norfolk Southern Railroad. Wayne Township near Passaic, New Jersey. Eugenia K. Roman, P.E.. 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. Is a . number. with units. It can be positive or negative.. Example: distance, mass, speed, Temperature…. Chapter 3: . VECTORS. 3-2 . Vectors and Scalars. Scalar. Is a quantity with both . direction. In the next two lectures we will discuss how to measure various types of displacement and motion. These include:. Linear Displacement. Angular Displacement. Linear Velocity. Angular Velocity. Acceleration. Joe T. Evans, Jr.. Spencer T. Smith. Naomi B. Montross. Scott P. Chapman. Radiant Technologies, Inc.. May 8, 2017. To paraphrase the title of a famous novel:. How I learned to stop worrying and love the butterfly loop!. by . three . numbers: . . (. x. , . y. , . z. ), and a . position vector. – an . arrow . showing the displacement from . the origin to that position. . Vectors add like successive displacements or algebraically by . Scalar. A . SCALAR. is ANY quantity in physics that has . MAGNITUDE. , but NOT a direction associated with it.. Magnitude. – A numerical value with units.. Scalar Example. Magnitude. Speed. 20 m/s. 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 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? Examples should include: . velocity/speed, mass, force/weight, acceleration, displacement/distance. . Addition of vectors by calculation or scale drawing. . Calculations will be limited to two vectors at right angles. Scale drawings may involve vectors at angles other than .
