Force of Gravity in terms of Density

In summary, the conversation is about finding the equation for the Force of Gravity in terms of density. The person has been trying to plug in the equation for the density of a sphere into Newtons Gravity formula, but is having trouble. They are looking for someone to explain the math and reasoning behind it. The other person suggests that the only reason to use density would be to find the mass when only the density and volume of the body are given, and provides steps for calculating the mass and plugging it into the equation.

Does anyone know the equation for the Force of Gravity in terms of density? I have been trying to plug in the equatin for the density of a sphere into Newtons Gravity formula and keep hitting dead ends. And if you can show me the math and reasoning behind it please.

I'm not sure what you are looking for. The only reason to use density would be to find the mass when you only have the density and volume of the body involved. In which case you calculate the mass from the given density and volume and plug that answer into the equation.
 

Related to Force of Gravity in terms of Density

1. What is the force of gravity?

The force of gravity is a natural phenomenon that causes objects with mass to be attracted to one another. It is one of the four fundamental forces in the universe and is responsible for keeping planets in orbit around the sun and objects on Earth from floating off into space.

2. How is the force of gravity related to density?

The force of gravity is directly related to the density of an object or substance. The denser an object is, the greater its gravitational force will be. This is because more mass means more gravitational pull.

3. Why does a more massive object have a greater force of gravity?

The force of gravity is directly proportional to the mass of an object. This means that the more mass an object has, the stronger its gravitational pull will be. This is why larger planets like Jupiter have a stronger gravitational force than smaller planets like Mercury.

4. How does the force of gravity affect the density of objects?

The force of gravity does not directly affect the density of an object. However, the strength of the gravitational force can influence the density of objects. For example, if an object is pulled by a stronger gravitational force, it may become more compressed, resulting in a higher density.

5. Is the force of gravity the same everywhere on Earth?

No, the force of gravity is not the same everywhere on Earth. The Earth's gravitational force is not uniform due to variations in the density and mass of the planet. For example, the force of gravity is slightly stronger at the poles than at the equator due to the Earth's oblate shape.
