A low-frills patio or deck is pretty cheap. Everyone's definition of cheap is different, but decks can be had for as low as $1,000, according to Jessica Piha, a spokeswoman for Porch.com, a website that helps homeowners find the right contractor. But the average deck costs $8,300, Piha says. And how much is a cheap patio? The cost to install a 200-square-foot concrete patio is about $740 to $840 on average, according to HomeWyse.com, an online reference for home projects. But here's why you probably won't buy a cheap patio. If you're pining over someone's patio, you presumably don't want a concrete slab.
The acceleration due to gravity on the surface of the Moon. The mass of the Moon is 7.35 x 10^22 kg and the average radius of the Moon is 1.74 x 10^6 m. Plugging into the formula, we have: g = (6.67 x 10^-11 N-m^2/kg^2)(7.35 x 10^22 kg )/(1.74 x 10^6 m)^2 = (4.9 x 10^12 )/(3.03 x 10^12) = 1.6 m/s^2.
Your weight on the moon is a function of the moon's gravity. First, we know that gravity is a force that attracts all physical objects towards each other (but why this happens is largely unknown!). Second, the greater the mass of an object, the stronger the force of gravity. The moon is 1/4 the size of Earth, so the moon's gravity is much less than the earth's gravity, 83.3% (or 5/6) less to be exact. Finally, weight is a measure of the gravitational pull between two objects. So of course you would weigh much less on the moon. Imagine how far you could jump on the moon!
