PPT-Measuring Motions: Speed, Velocity, and Acceleration

91818 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. 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?. Measures How Fast . Velocity . Changes. Motion and Forces Unit Chapter 1 Section . 3. 1. Speed and Acceleration Can Change with Time. Acceleration. 1. Speed and Acceleration Can Change with Time (answers). The pitcher throws. The ball speeds toward the batter. Off the bat it goes. It’s going, going, gone! A home run!. Before landing, the ball went through several changes in motion. It sped up in the pitcher’s hand, and lost speed as it traveled toward the batter. The ball stopped when it hit the bat, changed direction, sped up again, and eventually slowed down. Most examples of motion involve similar changes. In fact, rarely does any object’s motion stay the same for very long.. 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?. Average speed. Speed is a . scalar. variable. Unit . = . length over time (m/s. ). Instantaneous velocity. Speed and direction of object at a particular instant in time. Velocity is a . vector. 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.) . 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.. Separation of motion in x-and y-direction . Equations for 2-d kinematics at constant acceleration. Projectile motion. Lecture 4: Motion in two dimensions. Velocity. , . .  . Position vector . 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). 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?. 2016. Measuring Distance. Meter . – . international unit for measuring distance.. = 50 m. 1 mm. Calculating Speed. Speed. (S) . = distance traveled (d) / the amount of time it took (t). . S = d/t. 3.2. 3.2 Acceleration. Think about a car at a stop light. When the light turns green, the car starts moving and the car’s velocity increased. The car began accelerating. Acceleration is the change in velocity divided by the time it took the change to occur. The Equation. Describe how you could measure the acceleration of a small vehicle as it runs down a slope in the laboratory.. TASK. Many different ways. https://www.youtube.com/watch?v=YUqwdD73610. There are different ways to measure acceleration here are a few..
