mooeypoo Posted October 10, 2008 Share Posted October 10, 2008 So what kind of time interval are we talking about if everything was reversed to the point where the Earth was part of the sun? How long ago was the Earth born using the above scenario? Troll. Reported. Read the rules. Link to comment Share on other sites More sharing options...
insane_alien Posted October 10, 2008 Share Posted October 10, 2008 So what kind of time interval are we talking about if everything was reversed to the point where the Earth was part of the sun? How long ago was the Earth born using the above scenario? you seem to assume that this has always been the case for eternity, it is not so. this might come as a shock to you but THINGS CHANGE WITH TIME. that corner shop you buy your newspaper at wasn't always there, people didn't always drive cars and the internet is fairly new to the world. and believe it or not, the world existed before you were born so you weren't always here.

traveler Posted October 10, 2008 Author Share Posted October 10, 2008 no. you would not be going at a constant velocity. A constant zero velocity because the distance is not changing. You can observe for what ever time you like, if the distance remains the same the velocity is zero. If you are accelerating at 9.8m/s^2 towards the center of the Earth, that means one second later your velocity is 9.8 m/s towards the center of the Earth, correct? At the two second mark your velocity is 19.6 m/s??? Link to comment Share on other sites More sharing options...
mooeypoo Posted October 10, 2008 Share Posted October 10, 2008 There is a spring mattress in the middle of the desert. A ball is, theoretically, bouncing up and down on top of it continously. The ball has velocity. It is moving. It will also never reach the center of the Earth. You are ignoring our questions and again jumping from subject to subject in hopes we will forget. We didn't. You're disobeying the rules. Troll. Reported. I suggest you read the rules again. Link to comment Share on other sites More sharing options...
traveler Posted October 10, 2008 Author Share Posted October 10, 2008 (edited) There is a spring mattress in the middle of the desert. A ball is, theoretically, bouncing up and down on top of it continously. The ball has velocity. It is moving. The ball's velocity is changing like a frequency wave. But there is no such thing as perpetual motion. The ball's velocity peaks and valleys will diminish until the velocity and acceleration curves flat line, so it's not continuous. It will also never reach the center of the Earth. So the velocity towards the center of the Earth is 0 m/s when the ball is on the ground not moving in relation to the center of the Earth? That means the ball has an initial velocity of 0 m/s, and at the one second mark the ball has a velocity of 9.8 m/s. At the two second mark the velocity is 19.6 m/s, providing the acceleration remains 9.8 m/s^2. But we all know that as the distance decreases, the acceleration INCREASES, so as the ball does get closer to the center of the Earth, not only is the velocity increasing, but so is the acceleration. Remarkable. :rolleyes: Edited October 10, 2008 by traveler Link to comment Share on other sites More sharing options...
mooeypoo Posted October 10, 2008 Share Posted October 10, 2008 Go learn physics, seriously, and stop trolling. Your physics claims are hideous. I'm calling the cavalry. Link to comment Share on other sites More sharing options...
