With all his gear, neil armstrong weighed 360 pounds on earth. when he landed on the moon, he weighed 60 pounds. why? a. his mass changed while traveling to the moon. b. the gravity on the moon is six times the gravity on earth. c. the gravity on the moon is less than the gravity on earth. d. he experienced the effects of a gravity slingshot.
C.The gravity on the Moon is less than the gravity on Earth.Explanation;Mass of an object is the amount matter in an object, and is always constant irrespectful of the place, be it on the earth or on the moon or on any other planet. Weight on the other hand is the measure of the gravitational pull acting on a body or an object. Therefore, weight depends on the gravitational acceleration of a place. Hence, weight vary from one place to another depending on the gravitational pull.This explains why the weight of Neil Armstrong was different when on the moon surface and when on the earth's surface, due to the difference in gravitational acceleration on the two surfaces. Gravitational acceleration on the moon surface being less than that on the earth surface means that he weighed less on the moon, 60 pounds.
C) The gravity on the Moon is less than the gravity on Earth.
Since Moon is smaller than Earth, any mass on Moon will experience less gravitational force and so that mass will weigh less on Moon.
C. The gravity on the Moon is less than the gravity on Earth.
The weight of Neil Armstrong changed because the gravity on the Moon is less than the gravity on earth. We can infer that the gravity on moon is one-sixth the gravity earth.Mass of Armstrong on earth and moon is the same. Mass is the quantity of matter contained in a substance. Since he has the same quantity of matter on earth and moon, his mass will be the same.
Weight is a function of mass and gravity on a body.
Since his weight reduced, we can infer that the gravity on the moon is lesser:
Weight = mass x gravity.
Weight and mass
C: The gravity on the moon is less than the gravity on Earth.
The difference between weight on the moon and the earth because the influence of the earth's and the moon's gravitational force on objects
The moon's gravitational acceleration is 1,622 m / s², smaller than the earth at 9.88 m / s²Further explanation
Mass is one of the principal quantities, which is related to the matter in the material, whereas weight is a force that leads to the center of the earth which is subject to the earth to matter (Earth's gravitational force)
So that the mass does not depend on the location of the object, while the weight can change depending on the position of the object
In international standards, the mass unit is kg while the weight is in units of newton
1 kg itself is the mass of a cylinder made of platinum-iridium
While the standard mass of an atom is determined according to the carbon-12 atomic mass of 12 atomic mass units
1 atomic mass unit comparable to 1.6605402.10⁻¹⁷ kg
Measuring the atomic mass using a mass spectrometer.
The mass itself can be measured by the arm balance while the weight is measured by the spring balance
One equation that can relate mass and force (weight) is
W = weight, N
m = mass, kg
g = gravity acceleration, m / s2
The pound of force or pound-force (lbf) is a unit of force or weight
1 lbf is equal to 4.5 N
Neil Armstrong weigh 360 pounds on earth = 360 x 4.5 N = 1620 N
Then (g earth = 9.8 m/s²)
w earth = m.g
1620 N = m .9.8 m/s²
m= mass = 165.306 kg
So the weight on the moon become :(g moon = 1.622 m/s²)
w moon = 165.306 kg . 1.622 m/s²
w moon = 268.1265 N = 59.584 lbf(pound-force) = ± 60 poundsLearn more
the Earth have more gravitation pull than the moon
