PPT-Distance and Displacement

Chapter 111 Frame of Reference Everyone wants to go fast Whether it is a gangster on a bike or an antelope running away from a cheetah To describe either of these motions correctly we need to have a frame of reference . 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 . What is displacement?. Displacement is how fluid rushes up when an object is added.. displacement occurs when an object is immersed in a liquid, fluid is then pushed up and occupies the object’s place.. Displacement Reactions. Lets look at the reaction between chlorine and potassium bromide. When chlorine is bubbled through potassium bromide solution (colourless), the liquid turns red-brown, because bromine forms.. 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. 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. . Today’s Learning Objectives. Know the terms in this chapter.. Why is a reference point needed to describe motion?. What is the difference between distance and displacement?. How do you add vectors?. Karen Chapple, Professor of City . & Regional . Planning. University . of California, Berkeley. Regional sustainability planning, urban displacement?. . =. 2040 Plan Bay Area. : . 2 million new residents, 1 million new jobs. PHYS 243. Giancoli. , Sec 2-1, 2, 3, 4. © . 2011, . B.J. . Lieb. Analysis of a Race. All distances measured from starting line.. Time measured by a stopwatch from sound of gun.. Initial speed will be zero. . 6.1 Work Done By A Constant Force. When a force acts upon an object to cause a displacement of the object, it is said that . work. was done . upon. the object. . In order for a force to qualify as having done . Name: . Hour: . Determine displacement based on distance measurements.. Calculate speed and velocity based on position and elapsed time.. Create and interpret distance-time graphs.. Calculate acceleration based on speed and elapsed time.. 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. 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..

The Initiative also benefits from generous funding from the European Commission..
