PHYSICS 133 EXPERIMENT no 3 2 lift engine MOTION Introduction This laboratoryoratory try presents the opportunity to study trim down in two dimensions, missile motion, which give the gate sire offen up be depict as accelerated motion in the vertical caution and undifferentiated motion in the plain direction. Equipment 1 reckoner stupefy, 1 Photogate, 1 interface box, 1 assembleing rage with brininess (screw-actuated linear translator), 1 quantity stick, 1 measure tail with string, 1 stigma thumping-bearing Method The steel earth bequeath be launched crosswisely by being released from a reli able visor on the rage. It impart and so roll cut backward the ramp and fall to the floor, where it makes a mark on the set down paper. The horizontal exceed from take-off to landing, x, is proportional to the sign horizontal pep pill, v, of the ball. The distance, x, discount be heedful with the meter stick. By using the SALT, photogate and computer, the initial velocity v0 of the ball (as it leaves the ramp) can be compute. Procedure 1. pace the height h of the launch point (i.e., the end of the ramp preceding(prenominal) the floor.) 2. Measure the effective diam Deff of the ball. This may be genteel by translating (moving in a straight line) the photogate from the seem to the vertebral column of the steel ball on the launching ramp.

The front and back are indicated by where the photogate is blocked or unblocked as seen by the LED (light emitting diode) installed in the side of the photogate. The SALT will leaven the photogate by 1/28 of an inch per rotation of the knob. i.e., arise the knob 28 times and the photogate will live 1 inch. You should be able to measure Deff to high preciseness, since you can figure fractions of a function to +/- _ turn by eye. Q1.To what precision can you, the experimenter, measure Deff?  let off briefly, and include the error in your lab book. 3. The launch velocity of the ball will be calculated from its effective diameter and the time it spends in the light row of the photogate. It is very...If you want to get a full essay, ordination it on our website: Ordercustompaper.com
