PPT-Motion Graphs Motion-Time Graph

Describing motion is occasionally difficult to do with words Graphs can help simplify this description greatly Position Distance from a starting point Velocity rate of change in position Acceleration rate of change in velocity. Sections 4.2 and 4.3. Updates & Reminders. The date and time of the final: Thursday, December 11 from 10 a.m. to 12 p.m. MLT 208. . There is no lab this week.. Test #1 will take place on Thursday, 9/18.. Equation of Motion for . Average . V. elocity. Position-Time Graphs. P. lot . the time data on a horizontal axis. The . position data on a vertical axis. Position-Time Graphs. Two . different runners. Describing the motion of an object is occasionally hard to do with words. Sometimes . graphs. help make motion easier to picture and therefore understand.. Remember:. Motion. is a change in position measured by distance and time.. Kinematics Terminology. Scalar vs. Vector. Scalar: . quantities that have only a size, but no direction. i. e. : . distance, speed. Vector: . quantities that have a size and direction. ie. : . displacement, velocity. Use the units of mass, length, and time.. Define displacement, velocity, and acceleration.. Use the units of displacement, velocity, and acceleration.. Measure velocity and acceleration.. Use distance-time and velocity-time graphs.. Physics. How to interpret a . Position. vs. time Graph. Low on the graph. .. High on the graph. .. Slopes uphill.. Slopes downhill.. 0. x. t. Near. Far.

Graphs Representing Motion. Velocity-time graph. Gradient = acceleration. Area . Motion graphs are an important tool used to show relationships between position, speed and time.. It’s an easy way to see how speed or position change over time. Distance vs. Time Graph. Shows an object’s position at a given time.. Uniform Motion and Uniform Accelerated Motion. Read pages 27-36. Average and Instantaneous Velocity. Average Velocity .  rate of change in position. . - Found by considering total displacement (change in position) in a time interval). (. pg. 30-55). Do Now. Why is it important to describe and analyze motion. ?. How fast?. How far?. Slowing/Speeding?. Rest/Constant velocity. What . are some of the different types of motion. ?. Translational – motion along a straight line. September 20, 2016. What do we already know about graphing motion?. We know how to draw and interpret position vs time (P-T) graphs. Straight lines = . . Positive slope Negative slope: Zero slope: . . Motion. Speed & Velocity. Acceleration. Newton’s First Law. Newton’s First Law of Motion. An object at rest will remain at rest and an object in motion will continue moving at a constant velocity unless acted upon by a net force.. Position. vs. time Graph. Low on the graph. ..
