A person weighs 120pounds on earth weighs 20 pounds on the moon how much does a 90 pound persob weigh on the moon
Just use a ratio
weight/90 =20/120
weight = 90(20/120) = ...
To find out how much a 90-pound person would weigh on the moon, we can use a simple ratio:
Weight on moon = (Weight on Earth / Earth's gravity) \* Moon's gravity
First, let's calculate the ratio of Earth's gravity to Moon's gravity:
Earth's gravity = 1 (since we are using it as the reference point)
Moon's gravity = 1/6 (approximately, since the Moon's gravity is about 1/6th of Earth's gravity)
Now, we can rearrange the formula:
Weight on moon = (Weight on Earth / 1) \* (1/6)
= Weight on Earth / 6
Therefore, a 90-pound person on Earth would weigh:
Weight on moon = 90 / 6
= 15 pounds
So, a 90-pound person would weigh approximately 15 pounds on the moon.
