WebThe "normal" here refers to perpendicular. This is because the normal force, usually represented with F_n F n or just N N, is a force that is directed perpendicular to the two surfaces in contact. It makes sense that the force is perpendicular to the surface since the normal force is what prevents solid objects from passing through each other.

WebMar 29, 2024 · Gravity is a force that pulls objects towards each other. The strength of the gravitational force depends on how much mass an object has. Mass is the amount of matter an object contains. So, the more massive an object is, the stronger its gravitational force. The most massive object in our solar system is the sun. Webthe gravitational field of the Earth extends infinitely throughout space but its intensity is so less that it doesn't effects bodies outside a certain limit. just like Andrew said, the strength of the gravitational field declines with the square of the distance which is known as the inverse square law; 1/x^2.

But we kind of imagine it as kind of what dictates what happens in the, amongst the stars and the planets and moons. While the electrostatic force at close range is a much stronger force. It can overcome the gravitational force very easily. sbm wins corner
