If a very smooth ball is rolled down an inclined surface with zero friction, the ball will continue to roll indefinitely for an infinite time, in an attempt to reach to the same height on the opposite hill!

Textbook Question

Chapter 6, Problem 12CQ

The gravitational attraction of the Earth is only slightly less at the altitude of an orbiting spacecraft than it is on the Earth’s surface. Why is it, then, that astronauts feel weightless?

Chapter 6, Problem 13CQ

Students have asked these similar questions

The acceleration due to gravity in the surface of the Planet Jupiter is 254 percent times that of Earth. An object has a mass of 45 kg here on Earth. What will be its weight at the surface of the Jupiter?

If an object weighs 3 x 105 N on the surface of the earth, what would its weight be at an altitude of 400 km above the surface of the earth?

For this problem, assume that the earth is a perfect sphere. Also, assume that if your mass is m, then the earth exerts a gravitational force on you of magnitude mg, where g = 9.8 m/s2 at all points of the earth's surface. a) Your mass is m = will the scale read? (Thanks to the Third Law, this is the same as asking for the normal force exerted on you by the scale.) b) Next you go to the Equator and stand on a scale. What does it read? The radius of the earth is 6.4 × 106 m. c) Suppose the earth were rotating so quickly that objects became “weightless" at the equator. How long would the day be? 50 kg. If you are standing on a scale at the North Pole, what
