What is the gravitional force between a mass of 20 kg and a mass of 100 kg that are 15 meters apart?
The gravitational force between the two objects is 59.31 Newtons.
What is the gravitational force between a mass of 20kg and a mass of 100kg that are 15 meters apart?
Sir Isaac Newton realized in studing gravitional force that two things were always true about the amount of gravitional force an object has and the effect it has on nearby objects What did he realize?
Yes..... Our Earth and the rest of the planets would fly away from the Sun if it had no gravitional force. But also the Sun would blow apart if it had no gravity! The Sun is a full-time Fusion nuclear bomb! If the Sun had no gravity then the force of the explosion would send the Sun's matter flying outward, but the gravitional pull keeps the explosion in place!
There's gravitational force between every two specks of mass in the universe. That would include between every two people. Regardless of where they are. The magnitude of the force between two 100-pound students sitting with their centers 20 feet apart is about 0.000000003695 Newton, or about 0.0000000133 ounce. There is also gravitational force between the lint in the pockets of each student. That force is much less, because the lint has so much lass mass.
Physically, gravitional force between objects is notices when the two objects are of different mass and are not separated by an "ideal" distance (the ideal distance being there the pulls of both are cancelled out). The gravitional force would cause a net movement of one object towards the other, the less massive towards the more massive.
How the gravitional force between two objects depends on the mass of the objects and the distance between them?
How does the gravitational force between two objects that are close together compare to the gravitational force between two objects as they move farther apart?
All objects with mass attract all other objects with mass. The force between two 1-kg masses 1 metre apart is 6.670E-11 Newtons. All gravitional forces are attractions, unlike electric or magnetic attraction that can be attraction or repulsion. Thus gravitation is the only force that could have caused the stars to form.
