PPT-Compare and Contrast Speed, Velocity and Acceleration

Bell Ringer 11713 Compare and Contrast Speed Velocity and Acceleration is the speed of an object in a particular direction MYP Unit Question What Moves YOU Area of Interaction Human Ingenuity. 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?. According to Google maps, one can get from Ms. . Poole’s house . to the . Georgia Dome . (about . 3 miles. ) in 10 minutes. What average speed are the map makers assuming we travel. ?. (Show ALL work!). 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?. 2.7 m/s. 2. While traveling along a highway a driver slows from 24 m/s to 15 m/s in 12 seconds. What is the automobile’s acceleration? (Remember that a negative value indicates a slowing down or deceleration.) . 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.. Describing changes in velocity, and how fast they occur, is a part of describing motion.. How are changes in velocity described?. The rate at which velocity changes is called. . acceleration.. Scientists can perform artificial transmutations by bombarding atomic nuclei with high-energy particles such as protons, neutrons, or alpha particles.. Displacement: . Is the distance from where you start to where you finish. . Δ. d=. d. f. -d. i. Velocity:. How fast and in what direction (vector quantity). V = ∆d/t. Speed: . How fast (scalar quantity). distance. traveled in a given time. Speed is a . scalar. Velocity (v): change of . position. over time. Velocity is a . vector. Where . Δ. means “change in” or final – initial. Average speed. 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. Acceleration is a change in velocity. Speed or direction. Centripetal Acceleration. Acceleration can mean a change in direction, not just speed. Centripetal acceleration. Acceleration that occurs in a circular motion. 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?. Acceleration is a measure of . the change in velocity per unit of time. When the velocity of an object is changing, it is . accelerating. Negative acceleration: . slowing down. Positive acceleration: . Displacement: . Is the distance from where you start to where you finish. . Δ. d=. d. f. -d. i. Velocity:. How fast and in what direction (vector quantity). V = ∆d/t. Speed: . How fast (scalar quantity). 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?.
