PHYSICS 133 EXPERIMENT NO. 3 2 arise engine MOTION Introduction This laboratoryoratory experiment presents the opportunity to pick up trend in two dimensions, projectile bm, which give the render buoy be depict as accelerated motion in the vertical caution and uniform motion in the horizontal direction. Equipment 1 reckoner set, 1 Photogate, 1 interface box, 1 launching rage with SALT (screw-actuated linear translator), 1 meter stick, 1 measure bob with string, 1 brace ball-bearing Method The steel ball bequeath be launched horizontally by being released from a reliable acme on the do. It willing then roll cut rearwards the force and fall to the floor, where it makes a mark on the set charge paper. The horizontal distance from take-off to landing, x, is proportional to the sign horizontal velocity, v, of the ball. The distance, x, fucking be measured with the meter stick. By using the SALT, photogate and computer, the initial velocity v0 of the b all (as it leaves the ramp) tail end be compute. Procedure 1. throwaway the height h of the launch point (i.e., the end of the ramp preceding(prenominal) the floor.) 2. Measure the effective diameter Deff of the ball. This may be cultivated by translating (moving in a straight line) the photogate from the effort 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 ( nimbleness emitting diode) installed in the side of the photogate. The SALT will leaven the photogate by 1/28 of an inch per gyration of the knob. i.e., arise the knob 28 times and the photogate will inspir e 1 inch. You should be able to measure Deff! to high precision, since you can figure fractions of a turn to +/- _ turn by eye. Q1.To what precision can you, the experimenter, measure Deff?  Explain 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, arrangement it on our website: OrderEssay.net
