Answer: a) The universal law of gravitation states that everybody in the universe attracts every other body with a force F which is directly proportional to the product of their masses and is inversely proportional to the square of the distance between them.
Hereof, how did Newton calculate gravity?
Newton’s insight on the inverse-square property of gravitational force was from intuition about the motion of the earth and the moon. The mathematical formula for gravitational force is F=GMmr2 F = G Mm r 2 where G is the gravitational constant.
Keeping this in consideration, how do you calculate gravitational potential energy?
The formula for potential energy depends on the force acting on the two objects. For the gravitational force the formula is P.E. = mgh, where m is the mass in kilograms, g is the acceleration due to gravity (9.8 m / s2 at the surface of the earth) and h is the height in meters.
How do you solve the universal law of gravitation problem?
How is gravitation different from gravity?
Gravitation is the acting force between two bodies. On the other hand, gravity is the force occurring between an object and the very big object earth. Gravitation also represents that this force is directly proportional to the product of the masses of both objects.
How the mass of Sun is to be calculated by applying the law of universal gravitation?
Because the gravitational attraction of our Sun for the Earth is the centripetal force causing the Earth’s circular motion around the Sun, we can use Newton’s law of universal gravitation to find the mass of the Sun without visiting the Sun.
What do Newton’s equations tell us?
In the first law, an object will not change its motion unless a force acts on it. In the second law, the force on an object is equal to its mass times its acceleration. In the third law, when two objects interact, they apply forces to each other of equal magnitude and opposite direction.
What is formula of universal law of gravitation Class 9?
Universal Law of Gravitation Every body on earth attracts every other body with a force which is directly proportional to product of their masses and inversely proportional to square of distance between them Force is exerted by all bodies This force is gravitational force Force ∝ 1/𝑟^2 How to Calculate Gravitational …
What is Newton’s conclusions on universal gravitation?
Newton’s law of universal gravitation is usually stated as that every particle attracts every other particle in the universe with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.
What is the formula for calculating universal gravitation?
M and m are the masses of two objects in question; R is the distance between the centers of these two objects; and. G is the gravitational constant. It is equal to 6.674×10–11 N·m²/kg².
What is the mathematical expression of universal law of gravitation?
Mathematically, gravitation force is given by F=r2Gm1m2.
What is the universal law of gravitation obtain a mathematical equation for it also give two points highlighting its importance?
=> F ∝ m1m2 / d2.
What is universal gravitational law write formula of gravitational force what is G In this formula What is value and unit of G?
The force is directly proportional to the product of their masses and inversely proportional to the square of the distance between them. In equation form, this is F=GmMr2 F = G mM r 2 , where F is the magnitude of the gravitational force. G is the gravitational constant, given by G = 6.673 × 10−11 N·m2/kg2.
