Universal Law of Gravitation Answers

The acceleration due to gravity on Jupiter is 23.1 m/s2, which is about twice the acceleration due to gravity on Neptune.

The image shows a model of the gravitational field around Earth.

The gravitational force between two objects is 2000 N. The mass of each object is reduced to one-third of its original mass.

The gravitational force between two objects is proportional to the product of the masses of the objects.

A probe orbiting Venus exerts a gravitational force of 2.58 × 103 N on Venus. Venus has a mass of 4.87 × 1024 kg. The mass of the probe is 655 kilograms. The gravitational constant is 6.67 × 10-11 N*m2/kg2.To three significant digits, the probe is × 106 m from the center of Venus.

The gravitational force between two objects is 45,000 N. What will be the gravitational force between the two objects if the distance between the objects is reduced by one-half?

Which changes would result in a decrease in the gravitational force between two objects? Check all that apply.increasing the distance between the objectsdecreasing the distance between the objectsincreasing the mass of one of the objectsincreasing the mass of both objectsdecreasing the mass of one of the objectsdecreasing the mass of both objects

A baseball has a mass of 0.145 kilograms, and a bowling ball has a mass of 6.8 kilograms. What is the gravitational force between them if their centers are 0.5 m apart?

Which are the effects of gravity on objects on the surface of Earth? Select 2 options.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 pull on the Earth is much stronger than the Earth’s pull on the object.
