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. This law was given by Sir Isaac Newton.
Keeping this in view, how do you find the G in universal gravitation?
The acceleration g=F/m1 due to gravity on the Earth can be calculated by substituting the mass and radii of the Earth into the above equation and hence g= 9.81 m s–2.
Moreover, how much would a 60 kg person weigh on the moon where the gravitational field strength is 1.6 N kg?
Answer and Explanation: Answer: The person weigh 96 N on Moon.
How much would a 60 kg person weigh on the moon?
For example, on Earth, where the acceleration due to gravity is 9.8 m/s2, a person who has 60 kg of mass weighs 588 Newtons (132 lbs). Whereas on the moon, where the acceleration due to gravity is about 1/6 of what it is on Earth, that same 60 kg person weighs just 98 Newtons (~22 lbs).
How would your weight and mass change if you were standing on a planet that was twice the size of Earth quizlet?
The force of gravity is the same for each object. The force of gravity is proportional to the object’s mass. If you stood on a planet having a mass four times that of Earth, and a radius two times that of Earth, how much would you weigh on that planet? the same as your weight on Earth.
What is universal law of gravitation explain with example?
Newton’s law of universal gravitation states that any two bodies in the universe attract each other with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between them. Mathematically, Fg=r2Gm1m2.
What is universal law of gravitation explain?
Newton’s law of gravitation, statement that any particle of matter in the universe attracts any other with a force varying directly as the product of the masses and inversely as the square of the distance between them.
Why is the black hole invisible?
Black holes are so massive that not even light can escape their gravitational pull, so by their nature they are invisible.
