Dimensional Analysis, Speed, Velocity, Acceleration and Free Fall. Review Outline:. Dimensional Analysis Problems (converting). What is speed?. Calculations using speed formula.. What is velocity? . Chapter 2. Kinematics: Description of Motion. Warmup. : . Movin. ’ On. Acceleration . refers to any change in an object’s velocity. . Velocity . not only refers to an object’s speed but also its direction. The direction of an object’s acceleration is the same as the direction of the force causing it.. 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.

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.). 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.. 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. Equations. - give the equation and units linking:. Average speed, distance, time. Acceleration, change in velocity, time taken. Distance time graphs – . label each line. Explain how to calculate speed using different parts of the graph. . F. ollow the same procedure as other force problems, but keep in mind:. 1) Draw a free body diagram for EACH object or for each junction in a rope.. How To Solve Tension Problems. F. ollow the same procedure as other force problems, but keep in mind:. Mr. Fedell. VT vs. PT graphs. A position-time (PT) graph tells you . where an object is.. A velocity-time graph tells you . how fast it’s moving.. **(VT graphs DO NOT give in position info!)**. When an object stays still for 10s, its velocity is . Acceleration. January 27. th. , 2011. Lesson 7. Speed –Time Graphs for . Acceleration. Acceleration is a description of the relationship between speed and time. . Essentially . it is a change in speed over time. . Unit 9.2. m/s. 2. average acceleration. a = . D. v. D. t. 50 m/s – 25m/s. 4s – 2s. = . = . 12.5 m/s. 2. B. C. A. A. C. none. B. n. f. –. . n. i. t. f. –. . t. i. 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.). What is acceleration?. If you’re traveling in a car at a constant speed of 50 mph, are you accelerating?. No, you’re not. . Acceleration is the rate of change of velocity. . Acceleration. In order for acceleration to occur, velocity MUST be .
