## Where in a planet is the gravitational force the strongest?

In the case of the earth, the force of gravity is greatest on its surface and gradually decreases as you move away from its centre (as a square of the distance between the object and the center of the Earth).

**At which point is the gravitational force on the satellite the greatest?**

As a satellite orbits in an elliptical path, the force of gravitation is greatest at the times when it is closest to the Earth; this force causes a greater acceleration and speed of the satellite along these nearest locations of its orbit.

### Which planet has the lowest gravitational force?

Mercury

Which planet has the smallest gravitational field strength? An object has a mass of 10 kg….

Planet | Diameter (Compared to Earth) | Gravitational Field Strength |
---|---|---|

Mercury | 0.4 | 4 N/kg |

Venus | 0.9 | 9 N/kg |

Earth | 1 | 10 N/kg |

Mars | 0.5 | 4 N/kg |

**At which point does the planet have the least gravitational force acting on it?**

The planet has the least gravitational potential energy when it is closest to the Sun. So, therefore, the planet has its maximum speed when it is closest to the Sun.

## When a satellite is in orbit around the Earth the force of gravity on the satellite?

True weightlessness only occurs in deep space where the gravitational force on an object is zero. A satellite in a stable circular orbit around Earth is continually in free fall. As it orbits, it experiences a gravitational force towards the centre of Earth, which causes it to change direction and ‘fall’ towards Earth.

**What is value of gravitational constant?**

Value of universal gravitational constant G is 6. 67×10−11 kgNm.

### Which planet has the highest density?

Earth

Earth is the fourth smallest of the planets—though in terms of the rocky planets, it’s the largest—but it’s the most dense. Jupiter is the largest planet in the solar system, but it’s Saturn—the solar system’s second largest planet—that takes the prize for least dense.

**What is the gravitational force on each planet?**

Gravity on other objects in space

Space object | g, gravitational field strength (N/kg) |
---|---|

Venus | 8.8 |

Earth | 9.8 |

Moon (satellite) | 1.7 |

Mars | 3.7 |

## How do you calculate the gravitational strength of a planet?

The gravitational strength of a planet really depends on its density, but I’m wondering how I’m supposed to create a formula where gravity is the function of a planet’s average density.. M= mass of planet. G= Newton’s gravitational constant. r= average radius of planet. Strength of a gravitational field: M*G/r^2 = g.

**Why is the Earth’s gravity the strongest at the surface?**

The field produced by the mass at larger radii cancels out. For a perfectly uniform density spherical Earth, the gravity is strongest at the surface. But for a realistic Earth, the density is higher deeper underground, so the strongest gravity is somewhere underground.

### What is a large spherical planet of radius r?

A large spherical planet of radius R, made of a material of density d, has a spherical cavity of radius R/2,with centre of cavity a distance R/2 from the centre other planet. Find the gravitational force one small mass m at the centre of the cavity. > A large spherical planet of…

**What is the relationship between density and gravitational force?**

First impressions are that density is directly involved. As the density of a given volume of mass is increased the gravitational force its surface also increase, but so does the distance between that surface and the center of mass. Again, the density is secondary to the total mass involved which has not changed.
