PPT-4.3 Velocity Speed is a description of how fast an object moves; velocity is how fast

In physics velocity is speed in a given direction When we say a car travels at 60 kmh we are specifying its speed When we say a car moves at 60 kmh to the north we are specifying its velocity. WHY More teens die from car crashes than any other cause and the first year is the most dangerous WHEN 64 National Teen Driver Safety Week October 1524 2014 WHO High school students age 14 along with their schools communities friends and families u Friction is so small it can be ignored. .. The person shown is wearing spiked shoes and can apply a force to the sled and push it along the ice. . Which force would keep the sled moving toward the right and speeding up at a steady rate (constant acceleration)?. MOTION. CHAPTER 2 correlates . MAIN TOPIC?. The main topic of this chapter is __________, which is a change in an object’s position relative to a ___________ point.. MAIN TOPIC?. The main topic of this chapter is . Lab. Lesson 5. January. A ticker tape is the most commonly used technology for objects moving in a straight line. As the object attached to the end of the paper moves, it pulls the tape through the timer. As the tape moves through the timer, dots are recorded at consistent time intervals. . Motion is relative. An object’s motion is always described in reference to another object. Relative Motion. When an object is said to be traveling at 60 km/. h (or at any speed), . it is implied that it is moving at 60 km/h relative to the Earth.. Answers to Fusion . Motion and Speed Answers. Skip 1, 2, and 4—See J#5 Motion Vocabulary. 3 . If an object changes its position, then it is IN MOTION. It is also changing speed and velocity according to the definitions of both. . Models. Models We Will Use. Wiring diagrams for Chemical Reactions. Mathematical Models (Differential Equations). Computer Models . (. RuleBender. ). What good are models?. Models are abstract descriptions of the world.. © 2015 Pearson Education, Inc.. Velocity and Speed. Speed measures only how fast an object moves, but velocity tells us both an object’s speed . and its direction. .. The . velocity defined by Equation 1.2 is called the . 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.. How are instantaneous speed and average speed different?. . Speed. Average speed is computed for the entire duration of a . trip (includes starts and stops so it slows your rate down), . and instantaneous speed is measured at a particular .

Initial project creates a frameworkfor MOVES expansionIdentify preliminar Velocity is a vector, speed a scalar. Average speed – total distance divided by time. Average velocity – total displacement divided by time. Speed and velocity may or may not have the same magnitude. 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.
