Review Assignment for Chapter 5, Section 1: Motion



Review Assignment for Motion in One DimensionDisplacement is…The length of the trip you travelled.The difference between where your trip ended and where it started.Where you are in relationship to a reference point.None of the above.Time is…A vector quantity.Measured in meters.Always an independent variable.Can be a vector and a scalar quantity.Vector quantities have…Magnitude and direction.Only direction.Only magnitude.Use GUESS to answer #4-7.4) A cart is traveling at 0.85 m/s for 1.5 seconds. How far does the cart travel?5) A ball is rolling down a hill. The ball accelerates from rest to 2 m/s in 4 seconds. a) What is the acceleration of the ball? b) How far does the ball roll in the 4 seconds?6) If your 215 mile trip to vacation spot. Including the stop for gas and snacks, your average speed for the trip was 45 miles per hour. How long did it take for you to reach your destination?7) How long does it take the skateboarder with an acceleration of 1.55 m/s2 to go from 0.5 m/s to 3.0?m/s?8) a) Define: position, distance, displacement, speed, velocity, acceleration (use words, not equations)b) Classify each term as a scalar or a vector.c) Write SI unit for each variable.For each scenario below: (a) Sketch a graph of position vs time.(b) Sketch a graph of velocity vs time.(c) Sketch a graph of acceleration vs time.9) Moving away from the reference point at a constant speed and then changing to a slower speed.10) Walking toward the reference point and gradually slowing to a stop when you get there.11) Standing still 15 m from the reference point.12) Negative velocity and positive acceleration.13) What does the slope of the line on a distance vs. time graph represent? _________________________14) For the plots below, determine the velocity of the object... a. from 0.0 - 5.0 secondsb. from 5.0 - 10.0 secondsc. at 13.0 seconds????15) What does the slope of the line on a velocity vs. time graph represent?_________________________16) For the plots below, determine the acceleration of the object... a. from 0.0 - 5.0 secondsb. from 5.0 - 10.0 secondsc. at 13.0 seconds????17) For the plots below, determine the displacement of the object... a. from 0.0 - 5.0 secondsb. from 5.0 - 10.0 secondsc. from 0.0 - 15.0 seconds??? ................
