Motion in Gravitational Fields Multiple Choice Quiz 8

If the mass of the Earth was doubled and its radius was also doubled then the new value for the acceleration due to gravity on Earth would be:

A newly discovered planet has both a mass and radius that is double that of the Earth. What is the acceleration due to gravity on this planet?

The value of acceleration due to gravity on three planets, as well as their masses and radii, are given in the table below. The acceleration due to gravity on the surface of planet Z is closest to:

The gravitational potential energy of an object near Earth’s surface is changed when you:

Planet T-Trot has a mass that is 5 times greater than the Earth and a radius that is 3 times greater. What is the acceleration due to gravity on planet T-Trot?

Two astronauts landed on a very small asteroid orbiting the Sun between Mars and Jupiter. They experienced almost negligible weight force. Which statement explains this?

A satellite is in a stable geostationary orbit around the Earth. Which choice best shows the satellite’s path (solid arrow) if the gravitational force acting on it was somehow “switched off” which it was at point X?

The acceleration due to gravity on a planet is determined by the mass of the planet and its radius. Use the information in the table below to determine which planet has the largest acceleration due to gravity.

Mercury, the innermost of the Solar system’s planets, has a mass of 3.3 × 1023 kg. The average distance between Mercury and the Sun is 57,909,175 km. If the force of gravity keeping Mercury in orbit around the Sun is equal to 1.30546 × 1022 N, the mass of the Sun must be

Which statement is correct?

The diagram represents the gravitational field around planet X. If planet Y has the same mass but half the density, which diagram would best represent its gravitational field?
