What is the weight of an 80 kg person?
Method 1: First of all what does an 80 kg person weigh on the Earth? Weight is the force of gravity, F = ma, where a = 9.8 m/s2 on the Earth. Thus, 80 kg weighs 80 kg x 9.8 m/s2 = 784 kg m/s2, or 784 Newtons. The surface gravity of Mercury is 0.39 that of Earth’s (table 10-1), so 80 kg weighs 784 N x 0.39 = 306 N.
What is the weight of a man who has a mass of 80kg?
We would take the mass given, 80 kg, and multiply it times the acceleration of Earth’s downward pull on that mass, 9.8 m/s/s. So the weight on Earth is 784 newtons.
What is the mass of a 75 kg person on the moon?
The weight of the man in earth can be calculated by W=mg=75×9.8=735 N. While g is gravitational force and has the value of 9.8 m/s2. We know that a person weighs six times less on the moon than on the Earth. As the Moon has one sixth of the gravity of Earth, his weight in moon would be 122.5 N.
What is the weight of a 70 kg astronaut on the moon?
For example on earth a 70kg person would weigh 686N (70kg x 9.8 ) whereas on the moon, where the gravitational acceleration is about 1.62 , that same 70kg person would weigh 113N. This means on a pair of scales calibrated for earth they would measure 11.5kg. G-force is another name for the acceleration due to gravity.
What will be the weight of a person on the earth who weighs 9n on the moon?
Answer Expert Verified 54 newton . because moon gravity is 1/6 of earth gravity .
How much does a 80 kg person weigh on the moon?
The moon’s acceleration due to gravity is 1/6 of that of Earth. Thus, a person weighs 6 times more on Earth than the moon. This person will have a weight of 80 kg x 9.8 m/s^2 = 784 N on Earth and 130.7 N on the moon.
What is his mass on the surface of the moon?
On the Moon, g = 1.6 N/kg. In other words, a 1 kg mass has a weight on the Moon of 1.6 N….Summary.
| Mass | Weight |
|---|---|
| Measured in kilogrammes kg | Measured in newtons N |
| A measure of the amount of matter | The force of gravity acting on the object |
How much would a 78 kg person weigh on the moon?
The correct answer is 127.14 N. Concept: Mass: It is defined as the amount of matter it contains. It is measured in kg /g /milligram etc.
The radius of the Moon is Rm = 1.74 x 106 m, the gravitational constant is G = 6.67 x 10-11 N m2kg2 and the mass of the Moon is Mm = 7.35 x 1022 kg. Solve On the moon the acceleration due to gravity is 5 ft/sec2.
What is the mass of a man on Earth?
You mean, his *mass* is 80kg on Earth… his mass will be unchanged on Mars and Jupiter. His weight on Earth will be 80kg x 9.8m/sec^2 = 784 Newtons, which is his mass times the gravitational acceleration at Earth’s surface.
How to calculate the mass due to gravity?
The calculation formula used for this tool is: F g = m · g. Symbols. F g = weight or force due to gravity of object; m = mass of object; g = local gravity (e.g. standard earth gravity or g 0 = 9.80665ms-2) Mass of Object. Enter the mass of the object that you wish to determine the gravitational weight. Acceleration Due To Gravity
How to calculate the mass of an object?
Use this calculator to determine the weight of an object from its mass and the acceleration due to gravity at a particular geographical location or any other source of gravitational attraction. Formula. The calculation formula used for this tool is: F g = m · g. Symbols. F g = weight or force due to gravity of object; m = mass of object
