On my planet a man with a mass of 90 kg has a weight that is also 90 kg. On the Moon the same 90 kg man has a weight of 15 kg because the Moon is smaller and has less gravity.
We distinguish between mass (amount of matter) and weight (a downward force) so that mass stays the same wherever the man is, even if his weight changes.
Since Isaac newton's time we know that force is equal to mass times acceleration, and the unit of force is defined technically as the force that accelerates a mass of 1 kg by 1 metre per second, every second. That amount of force is a Newton.
If a 1-kg mass is dropped it will accelerate downwards at 9.806 metres per second per second, therefore the force on it is 9.806 Newtons.
So the weight of a 90 kg man is technically described as 90 x 9.806 Newtons, in other words 882 Newtons. On the Moon his mass is still 90 kg but his weight is now only 147 Newtons.
What else can I help you with?
How does the gravity of the planet vary with its mass?
The larger the planet mass, the bigger force of gravity it has.
How does the gravity of planet mercury vary with its mass?
The gravity of a planet like Mercury is directly proportional to its mass. This means that as the mass of Mercury increases, so does its gravity. Gravity is the force of attraction between two masses, and the larger the mass of an object, the stronger its gravitational pull.
Can planet grow without gravity?
Gravity comes with mass so since a planet has mass there is some gravity. the bigger the planet the more mass it has. smaller planets have less gravity. so either way there is always some gravity on a planet.
Do large planets such as Jupiter and Saturn have gravity?
Anything with mass has gravity. Anything massive enough to be considered a planet has noticeable gravity, whether it is a giant planet like Jupiter or a small planet like Mercury.
Why there is force of gravity on your planet?
Where there is mass there is gravity.
How do you calculate weight on other planets?
To calculate weight on other planets, you can use the formula: Weight Mass x Gravity. The mass of an object remains the same, but the gravity on different planets varies. You can find the gravity of a planet by looking it up online or using a formula. Then, multiply the mass of the object by the gravity of the planet to find the weight on that planet.
Can a planet suddenly lose its gravity?
No that is impossible. Gravity is related to mass, so while a planet still has mass it still has gravity.
How does a planet's gravity vary with its mass?
The gravity of a planet is directly proportional to its mass, and inversely proportional to the square of the distance from the center of mass. For the gravity on the surface of the planet, the distance is just the planet's radius. Thus, if a planet has three times the mass, it has three times the gravity. If you are three times as far away, the gravity decreases by a factor of nine.
What conclusion you make about the mass and gravity of planet?
more mass = more gravity
Where does the gravity of a planet come from?
Its mass
How does the gravity of a planet vary with it's mass?
Objects have a gravitational pull proportional to their mass.
How does a planet gets its force of gravity?
A planet gets its force of gravity from its mass and the distance from its center. The more massive the planet, the stronger its gravitational pull will be. Gravity is a fundamental force of nature that attracts all objects with mass towards each other.
