Set the frequency of the spark generator to f = 10 Hz (makes a mark every 1/10 second). If the air table has already been pre-aligned for you (In most cases, this has been done so there is no need to further incline the table.) Otherwise, incline the air table at an angle that is somewhere between 5º and 10º with respect to the horizontal, as measured approximately by a protractor. Notice that the air puck now moves relatively freely along the surface.
Plug in the air compressor power cord to begin supplying air used to cushion the pucks. Since you you will use only 1 puck for this experiment, set aside the other puck on a corner of the airtable. On top of this put a new sheet of white paper provided.
Lay down the sheet of carbon paper provided on the air table. Collecting Data for Measurement of “g” 1.
Pedal Air Table with 3 air pucks (2 x 500 g, 1 x 250 g), Puck Launcher, Air compressor, Ruler, ProtractorĪ. The horizontal (x) component of the velocity for each position is measured.Īir Spark compressor Generator Puck Launcher and controller The vertical (y) component of the velocity is obtained and used to experimentally determine the acceleration along the y-axis. The x- and y- components of the displacement and velocity vectors are experimentally obtained from the spark marks left by the puck. To study projectile (two-dimensional) motion, the puck is launched at an angle θ using a puck “launcher” which has a solenoid that suddenly expands when a capacitor is discharged by a switch. Finally, this is used to calculate the experimental “g” from the expression a = gsin φ, obtained from your Pre-Lab. From these marks, displacement measurements can be made and the resulting velocity and acceleration calculated. The underside of the puck sparks at its center point and burns a tiny dot at a pre-determined frequency. Since the table is inclined at an angle φ, the puck’s acceleration along the incline should be a = gsin φ (see Pre-lab). To reduce the damping effects of friction, this experiment uses pucks that move over a cushion of air provided by an air compressor and plastic tubing through its center. Experimental Details The first part of the experiment indirectly determines the acceleration due to gravity g by measuring the acceleration of an air-cushioned puck sliding down an inclinedĪirtable. Y = vyot - ½ gt2 vy = vyo – gt ay = - g x = vxot vxo = constant ax = 0ģ.

We summarize our description of projectile motion: Free Fall Motion Along the y-axis: Uniform Motion Along the x-axis where vxo = vo cos θ and vy = vosin θ. If the same object is launched at an angle θ above the horizontal, the resulting two-dimensional motion can be resolved into two independent motions: accelerated motion along the vertical and uniform motion (constant velocity) along the horizontal. The kinematical equations that govern its motion are (assuming upward motion is “positive”): y = yo + vyot - ½ gt2 vy = vyo - gt ay = - g B. time curve is a straight line with slope g and its displacement vs. This free-fall motion is an example of uniformly accelerated onedimensional (1D) motion. When an object is released (vyo = 0) subject only to the earth’s gravitational field, it moves with constant acceleration towards the center of the earth. to demonstrate the independence of motion along two perpendicular axes in projectile motion.to measure the acceleration of gravity using one-dimensional motion.Objective The objectives of this experiment are:
