To solve a quick and easy gravitational problem, you will need to know the mass of the objects involved and the distance between them. You can then use the formula F = G(m1m2)/r^2 to calculate the force of gravity between the objects. G is the gravitational constant (6.67 x 10^-11 Nm^2/kg^2).
Weight is a measure of the force of gravity on an object, while mass is a measure of the amount of matter in an object. In gravitational problems, weight is calculated by multiplying mass by the acceleration due to gravity (9.8 m/s^2 on Earth).
According to the inverse square law, as the distance between two objects increases, the force of gravity between them decreases. This means that the closer two objects are, the stronger the gravitational force between them will be.
Yes, the formula F = G(m1m2)/r^2 can be used for any two objects in a gravitational problem. However, keep in mind that the value of G may vary depending on the units used (e.g. kg or g).
No, gravity is a fundamental force that acts between any two objects with mass, regardless of the distance between them. However, the force becomes weaker as distance increases, making it practically negligible at very large distances.
