Now the weight of any object on the surface of Mars can be easily calculated. Our new colony member with a mass of 60 kg would find his weight to be: weight = F grav = M man g Mars = (60 kg)(3.8 m/s 2) = 230 N (just as we found above.)
Answer. the actual weight of a astronaut( m) = 68-kg. 9.8×68 = 666.4 = 6.7×10^2newton.
To convert 32 kg to N use direct conversion formula below. 32 kg = 32 N.
(b) The weight of a 90-kg astronaut in the space station is the gravitational force by Earth on the astronaut. On the surface of Earth, the astronaut weighs 90 × 9.8 = 882 N. Thus, the astronaut's weight in the space station is 783/882 = 89% of her weight on Earth.
It is given that the mass of a man is 75 Kg in earth.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.
How heavy is
98 kilograms? How much does
98 kilograms weigh in
pounds?
Convert 98 Kilograms to Pounds.
| kg | lb |
|---|
| 98.00 | 216.05 |
| 98.01 | 216.08 |
| 98.02 | 216.10 |
| 98.03 | 216.12 |
Weight (magnitude) = Fg = mg. Details of the calculation: Weight = Fg = mg = (60 kg)*(9.8 m/s2) = 588 N.
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.
On Earth, a 70 kg person weighs 706 Newtons (or 160 lbs). In orbit, the astronauts weight is 632 Newtons (142 lbs).
Weight is different from mass. Weight is the measure of the force of gravity on an object. The mass of an object will never change, but the weight of an item can change based on its location. For example, you may weigh 100 pounds on Earth, but in outer space you would be weightless.
Your weight on the Moon is 16.5% what you would experience on Earth. In other words, if you weighed 100 kg on Earth, you would weigh a mere 16.5 kg on the Moon. For you imperial folks, imagine you tipped the scales at 200 pounds. Your weight on the Moon would only be 33 pounds.
In science and engineering, the weight of an object is the force acting on the object due to gravity. Some standard textbooks define weight as a vector quantity, the gravitational force acting on the object. Others define weight as a scalar quantity, the magnitude of the gravitational force.
The Moon's gravity is much less than the Earth's gravity - approximately one sixth. So, a 100 kg astronaut weighs 980N on Earth. On the Moon, the astronaut would weigh only 162.2N. However, the astronaut's mass is 100kg where-ever they are.
And there would be no weight in outer space because there's no body to exert gravity, and it says they're traveling with constant velocity. So, there won't be any perceived weight due to the ship pushing on them either. So, d) is zero.
Weight is a measure of the force of gravity pulling down on an object. It depends on the object's mass and the acceleration due to gravity, which is 9.8 m/s2 on Earth. The formula for calculating weight is F = m × 9.8 m/s2, where F is the object's weight in Newtons (N) and m is the object's mass in kilograms.
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.

Answer: The person weigh 96 N on Moon.
If a person has a mass of 80kg, then they will weigh 80kg x 9.8m/s^2 or 784 Newtons on the Earth. That same person would weigh 80kg x 9.8m/s^2/3 or 261.33 Newtons on Mars, which the person might think was 26.66 Kg (although he would be incorrect since his mass has not changed).
For example, if you weigh 100 pounds on Earth, you would weigh only 38 pounds on Mercury. That's because Mercury weighs less than Earth, and therefore its gravity would pull less on your body. If, on the other hand, you were on heavy Jupiter, you would weigh a whopping 253 pounds!
Being that it takes the weight of an object on earth and converts it to lunar weight, the formula is Weight on the Moon= (Weight on Earth/9.81m/s2) * 1.622m/s2. To find the weight on the moon, we divide the weight on earth by the earth's force of gravity, which is 9.81m/s2.
The weight of an object is minimum when it is placed at the center of the earth because when an object is in the center, experiences gravitational pull from all directions & the weight of an object maximum on earth is on the poles.
Does the moon have gravity?
In space without gravity pulling down on them, Astronauts are essentially weightless. It is important to explore the difference between mass and weight. While Astronauts may not weigh anything in space and can float around freely, their body shape and size does not change.
Since the Moon is smaller than Earth, it has a weaker gravitational pull. In fact, the Moon only has 1/6 the gravity that Earth does. This means you weigh six times less on the Moon than you do on Earth!
National Aeronautics and Space Administration scientist Carolyn Leach said that each of the seven astronauts who flew aboard the shuttle Columbia in June lost up to six pounds after a day in orbit. As the nine-day mission wore on, they gained back all but two to three pounds, she said.
You're not as strong on the moon compared to say a kryptonian on earth, however, you and I would be around 6x stronger on the moon than on earth, not because our muscles would be around 6x stronger nor bigger but because of this force called “gravity” it is roughly 6x weaker than the gravity here on earth, yes, our
On the moon, there's no air to breathe, no breezes to make the flags planted there by the Apollo astronauts flutter. However, there is a very, very thin layer of gases on the lunar surface that can almost be called an atmosphere. In the moon's atmosphere, there are only 100 molecules per cubic centimeter.
Water retention can make you feel bloated, which may add on to your weight. In the morning our stomach is empty and the body's water is lost through sweat, respiration and urination. Due to these factors, we feel lighter.
The Earth's Moon has considerably less mass than the Earth itself. Not only is the Moon smaller than the Earth, but it is only about 60 percent as dense as Earth. Thus, the gravitational attraction on the Moon is much less than it is here on Earth, and a person weighs less on the Moon.
