Apr 10, 2024 · Newton’s Law of Gravitation. Newton’s law of gravitation can be expressed as \[\vec{F}_{12} = G \frac{m_{1} m_{2}}{r^{2}} \hat{r}_{12} \label{13.1}\] where \(\vec{F}_{12}\) is the force on object 1 exerted by object 2 and \(\hat{r}_{12}\) is a unit vector that points from object 1 toward object 2.

In the equation of gravitational force, G is a constant, called Universal Gravitational Constant or Gravitational constant. Its unit is Nm2kg-2 And the Value of G (Gravitational constant): 6.67408 × 10-11 Nm2kg-2 **Also read: How to measure G (Universal Gravity Constant)
With the law of universal gravitation, it is important to notice that two equal but opposite forces are present between any 2 objects. Earth pulls on the Moon and the Moon pulls on Earth with a force of equal magnitude. On the Earth’s surface, Earth pulls down on a 1 kg mass with a force of magnitude 9.8 N, and the 1 kg mass pulls upward on Earth w...
On the surface of a planet – such as Earth – the r in the Universal Law of Gravitation is very close to the radius of the planet. A planet’s center of mass is approximately at its center (for a spherical planet with azimuthal symmetry of density this is exactly true). In addition, we can safely ignore the increase in height off the surface of the E...
Jupiter has a mass of 1.9 × 10^27 kg. This is approximately 200 times the mass of Earth. Some astronomers believe that Jupiter has saved Earth from being bombarded by many more asteroids than it actually has in the past. Why is this? Solution Jupiter’s gravity can attract asteroids that stray too close to the planet, pulling them in and thus preven...
Q 1) Determine the magnitude of the gravitational attraction force between the Sun and the Earth, given that the mass of the Sun is 1.99 × 10^30 kg, the mass of the Earth is 6.0 × 10^24 kg and they are separated by 1.5 × 10^8 km as measured between their centers. Solution F = Gm1m2/r^2 m1 = 1.99 × 10^30 kg m2 = 6.0 × 10^24 kg G = 6.67 × 10–11 r = 1...

F g = G m 1 m 2 r 2. where: F g is the gravitational force between m 1 and m 2 , G is the gravitational constant equal to 6.67 × 10 − 11 m 3 kg ⋅ s 2 , and. m 1 and m 2 are masses. The force is directly proportional to the product of the masses. It is also inversely proportional to the square of the distance between the centers of mass.

- Yes. By definition, G is a constant.
For two bodies having masses m and M with a distance r between their centers of mass, the equation for Newton’s universal law of gravitation is. F = GmM r2 F = G m M r 2. where F is the magnitude of the gravitational force and G is a proportionality factor called the gravitational constant.
Newton’s Law of Universal Gravitation. where W is the weight of an object with mass m due to the earth’s gravitational force, G is the universal gravitational constant = 6.67x10-11 m2/kg2, ME is the mass of the earth, r is the distance between the object and the center of mass of the earth.
