Gravity Physics Questions & Answers

Gravity Physics Questions & Answers How far apart are Pluto and Charon? - CORRECT ANSWER- 2.0 × 10^7 m If the distance from the moon to the satellite is 2.6 × 106 m, what is the mass of the satellite? - CORRECT ANSWER- 450kg In the equation for the gravitational force between two objects, which quantity must be squared? - CORRECT ANSWER- d The gravitational force between two objects is 3600 N. What will be the gravitational force between the objects if the mass of each object is reduced to one-third of its original mass? - CORRECT ANSWER- NOT: 1200 N The universal law of gravitation states that the force of attraction between two objects depends on which quantities? - CORRECT ANSWER- the masses of the objects and the distance between them What is an effect of gravity on objects on the surface of Earth? Check all that apply. - CORRECT ANSWER- Objects "fall" toward the center of Earth. Objects are pulled by Earth but do not pull on Earth. Objects accelerate at a rate of 9.8 m/s each second. Objects travel at a rate of 9.8 m/s toward the center of Earth. Objects are pulled by Earth more strongly than they pull on Earth
