  1. So how far does the object travel in 2 seconds towards the center of the Earth when on the scale?
  2. F=m*a when an object is sitting on a scale? F=zero because a=zero or is the acceleration of the object 32.174 ft/sec^2??? Prove it!
  3. My comment, "A frame of reference has no time, therefore no motion" means that there is no relative motion between two objects unless you observe an interval of time. A frame of reference has no interval of time, therefore there is no motion. No change occurs in a zero interval, so there is no relative motion during a zero interval.
  4. A frame of reference has no time, therefore no motion.
  5. I never mentioned relativity. I merely expressed the idea that there is no such animal as a place in this universe that doesn't have a reference to measure motion.
  6. If I am not there to measure the motion, does that mean the particle doesn't travel a specific distance?
  7. Can you name a place in this universe that has no reference to measure motion, or are you thinking in terms of text books? The universe exists, or?
  8. No need to compare, we are talking about reality. If you tell me a particle traveled 10 feet, I know exactly how far that is. If you tell me observer A views the particle as having traveled 20 feet, and observer B views the particle as having traveled 5 feet, then I know for a fact that one or both observers are wrong. The particle traveled a specific distance, whether there is something to measure it against or not, regardless of how many different observations are made of the particle from different angles and distances in the universe. And rest doesn't mean zero velocity, it means zero acceleration.
  9. The train moves because the force (load) on the crank is less than required to stop the increase in rotational velocity of the crank at that specific RPM of the crank. The more load you put on the crank the lower the acceleration rate of the crank, to the point where the load is so great on the crank that it can no longer accelerate.
  10. Measure the speed you can throw that ball without the paperclip. Now glue the paperclip to the ball and retest the speed you can throw it. The force you exert on the ball is less without the paperclip, and a greater acceleration occurs when thrown. When the paperclip is glued to the ball the acceleration decreases, and the force increases. You can throw a ball faster, not harder. In order to throw it harder more mass needs to be added.
  11. In order to create a force you must have a load. The force can not be greater than the load. The force is created by the load, and can not exceed the load.
