Title: Space ship control under gravitation field Post by: Fu-Kwun Hwang on June 28, 2006, 10:44:16 am There are two space ships in circular motion (under the same gravitation field/same speed).
Suppose you can control the second space ship. You can click the button to change the velocity (in forward/backward/left/right) directions. Each click will change the same ammount of speed dv (dv can be change by slider). Default dv=2.5 and you can fire the button 10 times. If you double dv, then you can only fire 5 times. (If you reduced dv to half, then you can fire 20 times).

thank you enjoy! http://iwant2study.org/ospsg/index.php/interactive-resources/physics/02-newtonian-mechanics/08-gravity/284-gravity08 (http://iwant2study.org/lookangejss/02_newtonianmechanics_7gravity/ejss_model_gravity08_2/gravity08_2/2015-04-17_1501s.png) |
