Apr 12, 2024 · See all videos for this article. Newton’s law of gravitation, statement that any particle of matter in the universe attracts any other with a force varying directly as the product of the masses and inversely as the square of the distance between them. In symbols, the magnitude of the attractive force F is equal to G (the gravitational ...

t. e. Newton's law of universal gravitation says that every particle attracts every other particle in the universe with a force that is proportional to the product of their masses and inversely proportional to the square of the distance between their centers. Separated objects attract and are attracted as if all their mass were concentrated at ...
Learn the equation and definition of gravitational force, field, and mass, and how they relate to Newton's law of universal gravitation. See examples, questions, and tips on this high school physics topic.
- I'm confused about calculating all numbers like this "6.67 x 10^-11 m^3/kg*s^2". I know that is grav...Remember that 10² is 100. 10³ is 1,000. So 10^10 is a one followed by ten zeros, or ten billion. 10^-10 is going backwards: a decimal point followe...
- How do I calculate after I input the numbers in the formula? What does N stand for?N stands for Newtons, which is a unit of force. Could you clarify what you mean about inputting the numbers in the formula?
- Wait, so, I'm kind of confused. If g = G*(m1/r^2), then does that mean that the mass of m2 does not ...It does, but it is mostly not obvious. Everything has a gravitational pull, but it is not noticeable except for some exceptions; your dog, for inst...
- Is the "little g" just a gravitational field? And is it specifically Earth's gravitational field?Little g is the numerical value of Earth's gravitational field's pull at the Earth's surface. Another planet would have a different value for its o...
- i dont get itme neither
- Will `G` always be 6.67 x 10^-11 m^3/kg*s^2?Yes. By definition, G is a constant.
Learn how gravity is a force of mutual attraction between two objects that have mass or energy, and how to use Newton's universal law of gravitation to calculate its strength. Watch a video, see examples, and read comments from other learners.

- Actually andrew sir there is a problem which i want to discuss with you sir because one of my colleg...The gravitational force is F=G*m*M/d^2 (look at the video at 0:50) *But* the mass M of a planet is its density [rho] times its volume and the volum...
- Why would G not be constant everywhere in the universe? Would it be because the density of matter is...G is the universal constant for the gravitational force. It never changes. The units for G are m^3/(kg*s^2) g is the local acceleration due to grav...
- I've read that the acceleration due to gravity in the center of the earth is zero. I believe this is...If you are at the center of a sphere of mass, there is equal amounts of mass in all directions around you. This means that the gravitational pull o...
- what is the difference between the big G and the small gThey are not the same thing at all. G is the universal gravitational constant. It's the constant in the equation F = GMm/r^2. It's value is 6.67E-1...
- where can be a situation where is no gravity present??There is nowhere in the universe with no gravity. Every single object extends it's gravitational field infinitely into space. However the strength...
Jul 3, 2019 · Learn how Isaac Newton defined the attractive force between all objects that possess mass using a simple formula and a vector equation. Explore how to interpret the law of gravity, its gravitational fields, and its gravitational potential energy in different contexts and scenarios.
Aug 11, 2021 · Figure 13.2.1 13.2. 1: Gravitational force acts along a line joining the centers of mass of two objects. These equal but opposite forces reflect Newton’s third law, which we discussed earlier. Note that strictly speaking, Equation 13.2.1 13.2.1 applies to point masses—all the mass is located at one point.
