Physics 1AL ACCELERATED MOTION Fall 2009 1 Introduction In this lab you will study the motion of an object that travels with a constant acceleration. You will do experiments with an object in “ free flight ” and measure the acceleration of gravity. You will then investigate the relationship between the force applied to a cart by a fan and the cart’s acceleration, and what happens if you use two fans, back to back. __________________________________________________________________________ Pre-lab Questions: 1. Vector A has a magnitude of 6.5 m and is directed due north. Vector B has a magnitude of 8.2 m and is directed 35 o south of due east. What are the (a) magnitude and (b) direction (angle relative to east) of A + B ? Also, what are the (c) magnitude and (d) direction (angle relative to east) of A B ? Finally, what are the (e) magnitude and (f) direction (angle relative to east) of 3 A + 4 B ? 2. A ball is thrown up from the top of the tower. At each of the following instants is the ball’s acceleration larger than g, equal to g, zero, or g (assume up is positive and that g = 9.80 m/s 2 ) a) Just after leaving your hand and you are no longer touching it? b) When the ball is at the top of its path? c) Just before hitting the ground? d) Draw graphs of position vs. time, velocity vs. time, and acceleration vs. time for the ball from the instant it leaves your hand until the instant before it hits the ground. 3. A cannonball is shot vertically upward with a velocity of 20 m/s. While it is rising in the air ( choose one and explain your choice ): a. its velocity and acceleration are both upward. b. its velocity is upward and its acceleration is downward. c. its velocity and acceleration are both downward. d. its velocity is downward and its acceleration is upward. e. its velocity and acceleration are both decreasing.

Physics 1AL ACCELERATED MOTION Fall 2009 2 A. Motion under gravity – the Ball Drop: Procedure A1. Please place the echo sensor on the floor so that it is not near any chairs or the table. You may need to fold down the front so it is facing vertically. Open Logger Pro. A2. Zero the sensor by holding a piece of paper in front of it, like in previous labs.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
