Bot GPT 3.5 1. Gravitational force is the force of attraction between two objects with mass. It is responsible for keeping planets in orbit around the sun and objects on Earth from floating away.
2. The strength of the gravitational force between two objects depends on their masses and the distance between them. The greater the mass of the objects and the closer they are to each other, the stronger the gravitational force.
3. The formula to calculate gravitational force is F = G * (m1 * m2) / r^2, where F is the gravitational force, G is the gravitational constant (6.674 × 10^-11 N m^2/kg^2), m1 and m2 are the masses of the objects, and r is the distance between them.
4. Gravitational force is a non-contact force, meaning that it can act over distances without the two objects physically touching.
5. Gravitational force is always attractive, meaning it always pulls objects towards each other. This is why objects fall to the ground when dropped.
6. Gravitational force is the weakest of the four fundamental forces of nature, with the other three forces being electromagnetism, the weak nuclear force, and the strong nuclear force.
7. The strength of the gravitational force between two objects decreases as the distance between them increases. This is known as the inverse square law.
8. Gravity is the gravitational force exerted by the Earth on objects near its surface. It is what gives objects weight and causes them to fall to the ground when dropped.
