What happen to the weight of the object if the mass of the Earth decreases one half from its original mass without changing its radius?

In the given problem your weight will become half of original weight.

Does the Earth exert the same amount of gravitational force?

That’s what gives you weight. And if you were on a planet with less mass than Earth, you would weigh less than you do here. You exert the same gravitational force on Earth that it does on you. But because Earth is so much more massive than you, your force doesn’t really have an effect on our planet.

What would happen to the Earth if the sun suddenly shrunk in size and became a black hole?

What would happen if the Sun suddenly became a black hole without changing its mass? The black hole would quickly suck in the Earth. Earth would gradually spiral into the black hole.

What would happen if the mass of the Earth decreased?

If the mass will decrease, then gravitational attraction between earth and sun must decrease, and its angular momentum must decrease, which would result in greater orbit of earth and earth being cooler over the time, but instead the temperature of earth is increasing, why is it so?

Does Earth exert the same force?

The Earth always produces the same acceleration on every object. Although the gravitational force the Earth exerts on the objects is different, their masses are just as different, so the effect we observe (acceleration) is the same for each. The Earth’s gravitational force accelerates objects when they fall.

What is the difference between weight and mass in physics?

Mass is a measure of how much force it will take to change that path. Weight, on the other hand, is a measure of the amount of downwards force that gravity exerts on an object. This force increases with the object’s mass: the more inertia it has, the harder gravity pulls.

What is the effect on the revolution of the Earth if the Sun is suddenly converted to black hole?

It is true that, if the mass of the Sun (or black hole, whichever is at the center of the Solar System) goes up, then the Earth’s orbit will be affected. Specifically, it would move to a smaller orbit. And of course the reverse is true if the mass goes down.

What would happen to Earth’s orbit if the Sun collapsed?

Scientists estimate that the Sun will die in around 5 billion years. If the Sun miraculously disappeared, the Earth (and all the other objects in the Solar System) would continue their forward motion in a straight line off into space, instead of following their almost-circular orbits.
