Friction does, including air resistance. We can never observe
Newton's first law in our daily experience on Earth.
They are both celestial bodies, both makes part of the solar system, however, the Moon ( assuming you are referring to the Earth's natural satellite) makes revolution around the Earth, and Mars, which is a planet, makes revolution around the Sun.
1 newton = 0.225 pounds force, so 400 newtons = about 90 pounds force. 1 pound-force ≡ 0.45359237 kg × 9.80665 m/s2 = 4.4482216152605 N (exactly) = 32.17405 lbm·ft/s2 Also, if you use Google search try typing in ' 1 N to pounds ' . You can use Google.com's search for all kinds conversion tasks.
Yes. You're on to something important here. 'Kg' is a unit of mass. That means: how much stuff the thing is made of. It doesn't change. Whether the thing is on Earth, on the Moon, on Mars, or in space, it's still made of the same amount of stuff, so it has the same mass. That same mass has different weights in different places. On Earth, it doesn't matter what the object or the substance is, if it has 1 kg of mass, then it weighs 9.8 newtons. (About 2.205 pounds) When you take the same 1 kg of mass to the moon, it weighs only 1.62 newtons. And if you ever take it to Mars, it'll weigh 3.72 newtons there.
Strictly speaking no. For practical purposes yes.Mass does not change - 1 kg is 1 kg anywhere in the universe. However, 1 kg weighs less on the moon than it does on the earth. Weight is dependent on gravity.1 kg weighs 9.81 Newtons on the earth and about 1.64 Newtons on the moon.
list 5 thing about each planet that makes them different
i guess not but the mass and energy in the earth makes gravity. I guess... the energy and mass in the earth makes gravity.
There is no such thing as the Earth revolving around the Earth. This question makes no sense what so ever...
BACTERIA
Earth
A rocket
well the first thing was algae...and formed from there on
a bacteria
Single sell organisms
The same thing that makes you afraid to make the first move.
The first thing people saw Earth from above was likely from a high mountain or hilltop before the invention of flight. The first time Earth was seen from space was by astronauts during the Apollo 8 mission in 1968.
i my opinion it was an ape
Unless you count God himself (Genesis 1:1- 'In the beginning, God created the heavens and the earth.... and the spirit of God was hovering over the waters.') the first thing on earth would be water... it was formless and empty, dark and there was no land. The next thing God did make was light, then the sky, and then dry land. After this, he made vegetation, so the first thing on the dry ground of earth would've been plant life.
