Text: For a person standing in an elevator either stationary or moving at constant velocity, the normal force on the person's feet balances the person's weight. In an elevator that is accelerating upward, the normal force is greater than the person's ground weight and so the person's perceived weight increases (making the person feel heavier). In an elevator that is accelerating downward, the normal force is less than the person's ground weight and so a passenger's perceived weight decreases. If a passenger were to stand on a weighing scale, such as a conventional bathroom scale, while riding the elevator, the scale will be reading the normal force it delivers to the passenger's feet, and will be different than the person's ground weight if the elevator cab is accelerating up or down. The weighing scale measures normal force (which varies as the elevator cab accelerates), not gravitational force (which does not vary as the cab accelerates).

Question: is weight always equal to the normal force?

Text: In November 2003, Trump denied that the project had been delayed or that it was suffering from a lack of financing. Trump also said he was considering ''something on a larger scale'' for the project. In July 2004, Ruffin said the project had been delayed up to that point because of other business ventures, including Trump's reality television show, The Apprentice. That month, Trump and Ruffin announced revised plans for Trump International Hotel and Tower, a $300 million condominium-hotel with over 1,000 units. Although Trump held a Nevada gaming license, he chose not to include a casino on the property. Donald Trump's son Eric Trump later said, ''We have no problem getting a gaming license, but we wanted to do something different here. We wanted a true luxury resort experience. It's hard to have a high-quality product when you walk into 'ding, ding, ding' and there are people walking around in Hawaiian shirts with big plastic drink mugs.''

Question: does the trump hotel in vegas have a casino?
