PPT-Velocity, Acceleration, Jerk

Section 34a The difference quotient When we let h approach 0 we saw the rate at which a function w as changing at a particular point x Definition Instantaneous Rate of Change The . . (TG). Purpose:. This chapter introduces the ideal constant jerk S-curve (jerk is the derivative of acceleration), represented by a 2. nd. order polynomial in velocity. Its shape is governed by the motion conditions at the start and end of the transition.. Rotation Subjected to Multipoint Enforced Motion. Unit . 46. Vibrationdata. Introduction.

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?. Physics. Turning:. Turning counts as a form of acceleration because the direction of the velocity vector changes.. Turning requires a force that is perpendicular to the current motion of an object..

Practice. : A pool ball travelling at 2.5 m/s towards the cushion bounces off at 1.5 m/s. If the ball was in contact with the cushion for 0.20 s, what is the ball’s acceleration? (Assume towards the cushion is the positive direction.). A . vector quantity. is a quantity that has both magnitude and direction. Velocity, acceleration, and force are examples of vector quantities. . A . scalar quantity. is a quantity that has magnitude, but no direction. Time, mass, volume, and speed are examples of scalar quantities.. 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.) . 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). 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?. Displacement, Velocity, and Acceleration are the three vector quantities that describe the motion of any object during a specified time interval..
