PPT-Unit 2 Project: Distance, Displacement, Speed, Velocity, and Acceleration

Name Hour Determine displacement based on distance measurements Calculate speed and velocity based on position and elapsed time Create and interpret distancetime graphs Calculate acceleration based on speed and elapsed time. http://. www.aplusphysics.com. /courses/honors/kinematics/. honors_kinematics.html. Unit #2 Kinematics. Objectives and Learning Targets. Understand the difference between distance and displacement and between speed and velocity.. M. echanics. - the study of the motion of objects. we focus on the language, principles, and laws that describe and explain the motion of objects. Kinematics. is the science of describing the motion of objects using words, diagrams, numbers, graphs, and equations. . Chapter 2. Kinematics. deals with the concepts that . are needed to describe motion.. Dynamics . deals with the effect that forces. have on motion.. Together, kinematics and dynamics form. the branch of physics known as . 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?. June 2013. June 2013. June 2013. Pure linear motion. Linear motion movement of a body in a . straight. line or . curved line. , where . all parts . move the same distance, in the same direction over the same time.. 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. . Describe the speedometer on a car that is entering a highway, drives for 25 miles and then exits the highway.. Consider the two situations below. When a shuttle bus approaches a stop, the driver begins to apply the brakes to slow down 5.0 s before actually reaching the stop. The speed changes from 9.0 m/s to 0 m/s over 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. Know . The definition of scalar and vector quantities. Understand. Concept of distance, displacement, speed and velocity. Be able to . Determine distance and displacement in a given situation with units. behaviour. of the universe, from the very smallest scales of sub-atomic particles to the very largest in cosmology. It applies these laws to the solution of practical problems and to the development of new technologies. . Velocity and acceleration Measuring an objects motion speed Speed is calculated by dividing distance by time S = d/t 5.0 km/h 2.5 m/s 45 mph velocity Velocity is the same as speed, but you tell the direction of motion in the answer. Vectors, Scalars, and Motion!. Vector vs. Scalar Quantities. Scalar. . Quantities:. Only has . magnitude . Vector . Quantities:. Have . magnitude. AND . direction. Represented with an arrow. + or – indicates the direction. 9/18/18. What Is Motion?. Motion is when an object changes place or position. . To properly describe motion, you need to use the following:. Start and end position?. Movement relative to what?. How far did it go?. Definitions . Speed. : speed of an object is define as the distance traveled by it per unit time .I.e. speed of an object tells us how fast an object moves. Expression for speed : let distance traveled by an object be S in time t .then.
