13.6 & 13.7 Gravity Fields
Fichas del conjunto (7)
- 1What is the value of Earth’s gravitational field at the center of Earth?0
- 2If you stepped into a hole that passed completely through Earth, you’d oscillate down and up. How long would a one-way trip take?between 30 minutes and one hour
- 3A friend suggests you could launch a rocket by drilling a hole completely through Earth. Your friend says a rocket dropped into the hole would accelerate all the way through the earth and shoot out the other side into space. Will that work?No
- 4If you stand on a shrinking planet, so that you are getting closer to its center, your weight WILL increase. But if you go inside the planet and get closer to the center, your weight will decrease. Why does it decrease when you get underground?As you go deeper underground there is now mass above you pulling you back upward.
- 5If you stood on a ladder that was so tall that you doubled your distance from Earth’s center, how would your weight change?Your weight would be four times less.
- 6Suppose you stood atop a ladder that was so tall that you were three Earth radii from Earth’s center. How would your weight change?Your weight would be 1/9th as much.
- 7Consider a pair of planets that both somehow double in mass while keeping their same distance apart. By what factor does the force of gravity change between them?It would quadruple.
