what are the objectives of the lab?

1. Briefly describe the procedure of the laboratory and the equipment/software that will be used.
2. Briefly describe the theory, including all relevant equations and calculations. (make sure to refer the theory section of the experiment. including equation 6 and showing the work

I. OBJECTIVE Newton's Laws 1. To explore the relationship between the acceleration of a block and the force applied to it. II. EQUIPMENT -Air track and glider - the glider has a flag (or a two-post assembly) that is used to measure its horizontal speed as it passes through a photogate, similar with the procedure used in experiment 1 - Velocity & Acceleration. - Hanging mass - this consists of a hanger with removable masses. -Tape or string - to connect the masses. -One photogate and one timing system - the system used to measure the speed of the glider is identical with that used in experiment 1. You will be using either: - a timing system using a 2 MHz (2 megahertz = 2 million counts per second) clock. This timing system will read the photogate time with microsecond precision. All the time values will be displayed in seconds through the "Event Timing" program from your desktop. Make the following settings in the program: (i) select 2 as the number of events; (ii) check the "Photogate 1" box; (iii) check the "Intervals" setting. Press "Go", when ready to acquire data. or - a timing system using Pasco Data Studio. To use this timing system, open the Data Studio template "Photoevent Timing - flags or steel balls" located in the lab templates folder on the desktop. Some instructions on how to use this program are provided within the application. Press "Run" to start collecting the data. III.THEORY & BACKGROUND INFORMATION If the distance d (the length of the flag) is known, the speed of the glider will be given based on the time interval At measured using the timing system by: v = = d (1) Assuming that the glider is released from rest, its acceleration can then be calculated (see experiment 2) as: a = v2 2Ax (2) where Ax is the distance between the release point of the glider and the photogate. We will use a FLAG. Air Track d Glider (M-m) Ax Posts Newton's Laws Figure 1. Experimental set-up. Photogate Pulley Floor Page 3 I. OBJECTIVE Newton's Laws 1.
