why does the earth have gravitational force?
Answers
Answer:
yes Earth has gravity
Explanation:
the force of the gravity is the weakest at the equator because of the centrifuge force caused by Earth S rotation
Answer:
Explanation:
The universe has a lot of forces, a lot of pushes and pulls. We're always pushing or pulling something, even if only the ground. But it turns out that in physics, there are really only four fundamental forces from which everything else is derived: the strong force, the weak force, the electromagnetic force, and the gravitational force.
The gravitational force is a force that attracts any two objects with mass. We call the gravitational force attractive because it always tries to pull masses together, it never pushes them apart. In fact, every object, including you, is pulling on every other object in the entire universe! This is called Newton's Universal Law of Gravitation. Admittedly, you don't have a very large mass and so, you're not pulling on those other objects much. And objects that are really far apart from each other don't pull on
each other noticeably either. But the force is there and we can calculate it.
