truman Posted August 17, 2012 Share Posted August 17, 2012 Neither, but your assumption is flawed anyway; [straight] distance divided by time equals velocity. 'Speed' is different. I thought velocity had to have a directional factor ? eg 30mph east Link to comment Share on other sites More sharing options...
Jeffrey Shaw Posted August 17, 2012 Share Posted August 17, 2012 I thought velocity had to have a directional factor ? eg 30mph east No, but it has to be in one direction- hence 'straight' in my last post. Link to comment Share on other sites More sharing options...
barleycorn Posted August 17, 2012 Share Posted August 17, 2012 Neither, but your assumption is flawed anyway; [straight] distance divided by time equals velocity. 'Speed' is different. errr, no. Speed is a scalar quantity which measures how fast an object is moving (distance moved/time taken). Velocity is a vector quantity which measures the rate at which an object changes its position. When describing the velocity of an object you must also describe the direction. jb Link to comment Share on other sites More sharing options...

Jeffrey Shaw Posted August 17, 2012 Share Posted August 17, 2012 Well, I tried reading http://www.regentsprep.org/regents/physics/phys01/velocity/default.htm but my brain objected after a while... Link to comment Share on other sites More sharing options...
