Is mass zero if the object is in orbit around the earth?
The answer is false because. The weight of an object at the centre of the earth can be zero. not in the whole earth. the mass is constant it will not change with even if we are in space.
What would the gravity be on a planet twice the size of earth?
Part 7: What if Earth were twice as big? If Earth’s diameter were doubled to about 16,000 miles, the planet’s mass would increase eight times, and the force of gravity on the planet would be twice as strong.
What would your weight be at the center of the earth?
When you’re at the center of the earth, you’d have equal amounts of gravitational force pulling you in all directions from the mass of the earth evenly distributed around you. Thus, the net gravitational force would be zero. This is also known as your weight. Additionally, g=Fg/m=0/m=0.
What is the mass of the object on the earth?
The Earth mass excludes the mass of the Moon. The mass of the Moon is about 1.2\% of that of the Earth, so that the mass of the Earth+Moon system is close to 6.0456×1024 kg….

What would happen if the Earth was twice as far from the sun?
Also, that gravitational force had to predict the correct behavior of falling bodies on Earth, as observed by Galileo. In other words, if a planet were twice as far from the Sun, the force would be (1/2)2, or 1/4 as large. Put the planet three times farther away, and the force is (1/3)2, or 1/9 as large.
What would happen if the Earth was half its size?
As the Earth is methodically sliced in half, its mantle and core would be exposed to the vacuum of space, causing massive earthquakes that would be felt everywhere on the planet. Those who are the furthest from the split would have the best chance of surviving the longest, at least from the initial earthquakes.
What is the weight of 1 kg mass on Earth?
an object with a mass of 1.0 kilogram will weigh approximately 9.81 newtons on the surface of the Earth (its mass multiplied by the gravitational field strength), since the newton is a unit of force, while the kilogram is a unit of mass.
What will be the mass and weight of a body at the Centre of Earth?
Thus, weight is zero where the acceleration due to gravity is zero. Hence, the weight of the body placed at the center of the earth is zero.
Can mass be equal to weight?
They convert it into kilograms for convenience.) On the surface of the Moon, where the force of gravity is weaker (about a sixth Earth’s gravity, or 1.6 newtons per kilogram), a 70-kilogram astronaut would weigh only 112 newtons. This is about what an 11.5-kg object would weigh on Earth.
How is weight and mass the same?
In scientific contexts, mass is the amount of “matter” in an object (though “matter” may be difficult to define), whereas weight is the force exerted on an object by gravity. Objects on the surface of the Earth have weight, although sometimes the weight is difficult to measure.
Why is the Earth not a perfect sphere?
The earth is spinning, causing it to slightly flatten like a pizza crust thrown and spun in the air. As a result, the earth is an oblate spheroidand not a perfect sphere. If you stand at sea level on the equator, you are 6378 km from the center of the earth. In contrast, at each pole, you are only 6357 km from the center of the earth.
How much does an object weigh on Jupiter’s surface?
Yet on Jupiter’s surface an object weighs only about 3 times as much as it would on earth. The explanation to this involves Jupiters… A 440 N woman stands on top of a very tall ladder so she is one earth radius above Earths surface. How much does she weigh?
What would happen to your weight if the Earth were not spinning?
If the earth were not spinning, you would be heavier as you would feel the full force of gravity. Since there is more centrifugal force at the equator to cancel gravity, your overall weight at the equator versus at the poles is even less. The centrifugal force on your body at the equator is 0.034 m/s2times the mass of your body.
How much less do you weigh at the equator?
Compare this to the acceleration due to gravity which is about 9.8 m/s 2 and you can see how tiny an effect this is – you would weigh about 0.3\% less at the equator than at the poles! There is an additional effect due to the oblateness of the Earth.
