  1. Apparent Weight and Artificial Gravity

  2. To measure weight:  “Weight” is the force of gravity acting on an object.  We use a spring scale or bathroom-type scale to balance the force of gravity acting on the object.  If the object is at rest or moving at a constant velocity, then the measurement of weight is valid! FBD and Force Statement: FBD and Force Statement: FT FN Fg Fg FT= Fg FN= Fg

  3. Accelerated System If the system is accelerating, then the apparent weight measured will be greater or less than the force of gravity (true weight) Accelerating up apparent weight > Fg Accelerating down apparent weight <Fg If the object goes into free-fall  apparent weight is zero!

  4. Example: • The apparent weight of a student (mass 40.0 kg) standing on bathroom scale in an elevator is measured as 650. N. Determine the acceleration of the elevator.

  5. Simulated Gravity Astronauts in long-term flights experience negative health effects due to “weightlessness” A rotating space station can be used to produce “artificial gravity” A vision of a space station from 2001 A Space Odyssey..... Example: A large space station has a radius of 400.0 m. What period of rotation would be required to simulate Earth’s gravitational field at the outer radius of the space station? HW: Handout + Practice 7-10 page 150
