Why do we experience weightlessness in space?
Because there are no contact forces acting on us. Gravity is the only acting on us. A body experiences weightlessness when gravity is the only force acting on it.
Which of these develop when gravity pulls gas and dust together with enough pressure to ignite nuclear fusion?
Having some trouble seeing your list of choices from here.But stars do.
How does gravity affect the stars moon an planets?
Gravity keeps the planets in orbit around the sun and the stars and the stars in orbit around the center of the galaxy. Gravity also holds the stars together against their own internal pressure.
Did gravity form stars?
Yes. Stars form when clouds of gas and dust, called nebulae, collapse under the force of gravity.
What would happen to stars if there was no gravity?
If there were no gravity, period, there would be no stars. If gravity ceased to work, there would be a whole lot of violent explosions as the nuclear, mechanical and other forces within the stars popped the stellar balloons, so to speak.
Why is the pressure extremely high for the nuclei to crash into one another in stars?
gravity acting on the mass of the star.
Can a object have weight without having mass?
No. Weight is the result of gravity acting on mass.
Measure of force of gravity acting in an object?
weight, The weight of an object is the force of gravity acting on it.
Is gravity a force?
Yes, gravity is a force that pulls us towards the Earth 🌍.
Why do we experience weightlessness in space?
Because there are no contact forces acting on us. Gravity is the only acting on us. A body experiences weightlessness when gravity is the only force acting on it.
Are stars rounded by gravity?
yes because they levitate in space gravity does hold stars up
Do stars twinkle due to refraction or gravity?
Stars in the universe twinkle because of refraction not gravity.
Which of these develop when gravity pulls gas and dust together with enough pressure to ignite nuclear fusion?
Having some trouble seeing your list of choices from here.But stars do.
When apple is falling the gravitational force is acting but why force of gravity is not acting here?
I have no idea what you mean - the force of gravity acts everywhere.
What is the force called that gravity is acting on you?
The force exerted by the earth towards itself,known as the gravitational force is called that gravity is acting on you.
The force of gravity acting upon the mass of an object?
That's usually called the object's "weight". Like say if you're talking about the forces of gravity between you and the Earth, the force of gravity acting on you is your weight on the Earth, and the force of gravity acting on the Earth is the Earth's weight on you, and they're equal.
How are stars made with no gravity?
They aren't. Stars form as a result of a cloud of gas collapsing due to gravity.
