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!). Weight is a measure of that gravitational pull. Second, the greater the mass of an object, the stronger the force of gravity. The Moon's mass is about 1.2% of the Earth's mass (1/80th), so the Moon's gravity is much less than the Earth's gravity: 83.3% (or 5/6) less to be exact. Other related facts: the Moon is 1/4 the size of the Earth by diameter, and 1/50 the size by volume. The bottom line is that you would weigh much less standing on the Moon. Imagine how far you could jump on the Moon! The Apollo astronauts apparently had fun :-) Your Weight On The Moon. If you were to take a scale to the Moon and stand on it, here's what it would say:
