The remains of a massive star pulled into a small volume by gravity?
A black hole is formed when the remains of a massive star collapse under their own gravity, creating a region of spacetime where gravity is so strong that not even light can escape. The mass is concentrated into a small volume called the singularity at the center of the black hole, surrounded by an event horizon beyond which nothing can escape.
Does gravity have volume?
All substances have volume, but gravity is not a substance; gravity is a force and has no volume.
Why is the density of lead the same on the Moon as it is on Earth?
Density is based off mass and volume, not weight and volume. Weight is a measurement of gravity, and changes based on strong the pull of gravity is in the area. Mass is a measurement of the amount of matter in an object, and does not change based on the pull of gravity. Density is Mass/Volume. Volume is a measure of how much space an object occupies. The more condensed matter is, the higher its density.
Why does Jupiter have more moons than mars?
Jupiter is far more massive than Mars and therefore its gravity field covers a larger volume of space so that it has been able to capture more debris from that volume.
What is the formula for calculating weight if density and volume are given?
Weight = (density) times (volume)The definition of density is mass/volume .Now [ weight = mass x gravity ], so [ mass = weight/gravity ], and [ density = weight/gravity x volume ] .So Weight = (density) x (volume) x (gravity)
What is the law of density?
The law of density states that the density of a substance remains constant under uniform conditions of temperature and pressure. It means that the mass of a substance per unit volume remains the same, regardless of the size of the sample. Mathematically, density is calculated by dividing the mass of an object by its volume.
Does weight depend on mass and its volume?
Weight depends on mass and the acceleration due to gravity, while volume is a measure of the space occupied by an object. The weight of an object may change depending on the mass and the gravitational pull, but the volume of the object remains constant as long as its shape and size do not change.
Do mass and volume have to do with gravity?
yes
What happens to an objects mass weight and volume when taken into space?
Mass: Does not change Weight: The weight will be zero, if you are not standing on a large massive body (like the moon). When in orbit you are actually in continuous freefall around the planet with a sufficient tangential velocity component. Volume: If the object is filled with gas from the earth's lower atmosphere the gas will exert this pressure on the sides of the object, prehaps causing the object to explode.
What happens to density if an objects volume remains constant but its volume is decreased?
If an object's volume remains constant but its mass is increased, its density will also increase. Density is defined as mass divided by volume, so if the volume stays the same while the mass increases, the density will increase as well.
Is vacuum has a zero gravity?
Vacuum itself does not have gravity. In a vacuum, there is an absence of matter and gas particles, so there is no medium for gravity to act upon. Objects in a vacuum are subject to the gravitational pull of nearby massive bodies like planets or stars.
How can you describe the relationship between mass and volume for these samples?
For substances with constant density, their mass is directly proportional to their volume. This means that as the volume of the substance increases, its mass also increases in a linear fashion. The relationship between mass and volume is described by the density of the substance, which remains the same regardless of the amount of the substance present.
