conical pendulum is one in which the mass swings around at constant speed in a (hori-zontal) circle , as shown in Fig. 3.2, rather than swinging back and forth in a vertical planeas in Fig. 3.1.
Newton’s first law states that an object will move at constant velocity if no forces are imposedon it. Thus, defining thexaxis to be along the direction of the velocity, its motion obeys:
Computers are used for data analysis in any modern physics laboratory, and the Physics101 lab is no exception . We have built our data analysis system around the programExcel,which is widely used on and off campus. We’ve added someWorkshop Physics(WP)toolstomake graphing data easier, and to let you do regression calculations with uncertainties, butotherwise we are using the standard, off-the-shelf software.1
Springs provide a useful model for many physical systems that exhibit oscillatory behavior.The key characteristic of springs is that, when stretched or compressed by an amount Δxfrom their relaxed position, they exert a force proportional to Δx:
The lowest-frequency light that will produce the photoelectric effect is called the threshold frequency. (a) The threshold frequency for indium is 9.96 × 1014s...
