HTML_EDITOR Intro Page true true This java applet - "projectile_motion0.xml"" was created by J. Hasbun with Easy Java Simulation (Ejs) from Francisco.

---

This is a simulation of a projectile launched at an initial speed, vo, an initial angle, th0, and an initial height, yo. The equations of motion are such that x=xo+vox*t, y=yo+voy*t-gt²/2, with vx=vox, vy=voy-gt. The user has the capability to change, vo, tho, yo, and g to investigate various effects due to such changes. ]]> 10 true VARIABLE_EDITOR Var Table true true dt double xo double yo double tho double th double vo double vox double voy double g double t double x double y double vx double vy double double CODE_EDITOR Init Page true true CODE_EDITOR Evol Page true true false Elements.Frame Frame true Frame border true 376,366 false Elements.Panel Panel Frame north border 100,250 false Elements.PlottingPanel PlottingPanel Panel center Height versus Horizontal Position X (meters) y (meters) true true Elements.Trace Trace PlottingPanel x y true NO_MARKER Elements.Particle Particle PlottingPanel x y 0.5 0.5 NO_MARKER red false Elements.Panel Panel2 Frame center grid:2,2,0,0 0,0,0,0 Elements.Slider vo Panel2 west vo 0.0 30.0 vo=##.## Elements.Slider theta Panel2 center tho 0.0 90.0 theta=##.## Elements.Slider yo Panel2 yo 0.0 50.0 yo=##.## Elements.Bar vx Panel2 vx vx=##.## white white Elements.Bar vy Panel2 vy vy=##.## white white Elements.Field g Panel2 g -9.8 g=##.## false Elements.Panel Panel3 Frame south grid:2,3,0,0 100,35 Elements.Button Play Panel3 west Play _play() 100,50 Elements.Button Pause Panel3 center Pause _pause() Elements.Button Initialize Panel3 east Initialize _initialize() 100,50 Elements.Button step Panel3 step _step()
