PPT-Position, velocity, and acceleration in 2-d

Separation of motion in xand ydirection Equations for 2d kinematics at constant acceleration Projectile motion Lecture 4 Motion in two dimensions Velocity   Position vector . 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?. Kinematics:. Velocity, Speed, and Rates of Change. Greg Kelly, Hanford High School, Richland, Washington. Rectilinear Motion. Motion on a line. Suppose a dog moves along a straight line so that its position . 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?. Equations of Motion for Constant Resultant Force. Also called ….. because………. …acceleration and resultant force are directly proportional. . s. uvat. equations. Also called …..

Initial speed will be zero. . ACT/PSAE practice. Intro to acceleration. What does it mean in common language?. What does it mean to a physicist? (That’s you!). First equation of acceleration. A = v/t. Standard unit for acceleration: m/s^2. Bell Ringer 11-7-13. 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. 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). . trajectory, vectors. . r, v, a, F. j. ,… . ,. coordinate axes x, y, z, free-body diagram, … . 2. Data:. . a table of known and unknown quantities, . including “implied data”.. 3. Equations . 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. 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. Get an . Ipad. , from my website click on Acceleration web notes on today’s calendar. Answer the following questions: . What . is acceleration?. Why is acceleration a vector quantity?. What does a position vs. time graph look like when showing changing velocity?. Defination. In non-uniform motion,the velocity of a body changes with time . For example, when a train leaves or approaches the platform its velocity changes with time. The change in velocity of an object with time is given by a physical quantity known as acceleration. .
