How does the four factors affects stability?
The four factors that affect stability are the center of gravity, the reaction forces, the buoyancy, and the moment of inertia. The center of gravity is the point at which the weight of an object is concentrated. It is the point at which the object balances when it is in equilibrium. If the center of gravity is located too far forward or backward, the object will be less stable and more prone to tipping over. When the object has its center of gravity located in the center, it will be more stable. The reaction forces refer to the forces that act on an object when it is in contact with another object. These forces include gravity, friction, and surface tension. If the reaction forces are not balanced, the object will be less stable. The buoyancy of an object is a measure of its ability to float in water or other fluids. The buoyancy of an object is determined by its density, shape, and size. If an object is too heavy, it will sink; if it is too light, it will float. An object’s buoyancy will affect its stability in water. The moment of inertia is a measure of an object’s resistance to changes in its rotational motion. The higher the moment of inertia, the more stable the object is. If the moment of inertia is too low, the object will be more prone to tipping over. These four factors all affect the stability of an object. The center of gravity affects the object’s balance, the reaction forces affect how the object interacts with other objects, the buoyancy affects how the object behaves in water, and the moment of inertia affects the object’s resistance to changes in its rotational motion. When these four factors are in balance, the object will be more stable.
What are the 3 factors of weight?
The mass of the object, the mass of the object that is attracting it and the distance between their centres of gravity.So your weight on the moon will depend on your mass, the moon's mass and the distance from your centre of gravity to the moon's.The mass of the object, the mass of the object that is attracting it and the distance between their centres of gravity.So your weight on the moon will depend on your mass, the moon's mass and the distance from your centre of gravity to the moon's.The mass of the object, the mass of the object that is attracting it and the distance between their centres of gravity.So your weight on the moon will depend on your mass, the moon's mass and the distance from your centre of gravity to the moon's.The mass of the object, the mass of the object that is attracting it and the distance between their centres of gravity.So your weight on the moon will depend on your mass, the moon's mass and the distance from your centre of gravity to the moon's.
Can you live on a brown dwarf star?
No. Even a brown dwarf, one that we would call "cool" for a star, still has surface temperatures far above the vaporization temperature of all matter. And even if you had perfectly insulating shoes, the gravity on the surface of even a small star would crush any material object instantly.
How does the downward component of the motion of a projectile compare with the motion of free fall?
well if you think about it free fall is just an object that falls down with no force besides gravity pushing on it. and projectile is also something or an object that has no force acting on it besides gravity. so there pretty alike. that is how they compare.
What is an object so massive that light cannot escape its gravity called?
A black hole is an object so massive that light cannot escape its gravity, due to the intense gravitational pull caused by its mass and density.
What is a massive and dense object from which light cannot escape its gravity called?
A "Singularity" or a "black hole".
Is there another place in outer space that has gravity?
Yes, every planet and every star has gravity. In fact, every object that has mass, has gravity. Black holes have so much gravity that even light cannot escape.
To escape from a planets gravity an object must reach a speed called the?
Escape Velocity
Is the escape velocity higher for the earth or the moon?
The mass of an object is the same wherever it may be. The weight of an object changes however. The weight of an object is the product of its mass times gravity. Gravity is greater on earth than it is on the moon, so an object will weigh more on earth.
How long does it take to escape gravity in a rocket?
It isn't clear what exactly you mean with "escape gravity". The effects of Earth's gravity (for example) extend all the way to infinity, while getting weaker and weaker at a greater distance. So in a way, an object moving away from Earth never "escapes gravity". If an object moves fast enough - about 11.2 km/second near Earth's surface - it is said to have reached "escape velocity", in this case, it is fast enough never to come back. A rocket will reach escape velocity in a few minutes.
What object is so dense and has such strong gravity that no light can escape it?
A black hole is an object with such strong gravity that not even light can escape its pull. This intense gravity is due to its extreme density, formed when a massive star collapses in on itself.
The downward pull of gravity on an object?
gravity=9.8m/s^2 (on the Earth's surface)
What is an object so massive that light cannot escape its gravity is a?
A black hole has so much mass that light can't escape from it once it passes the event horizon. It can still escape if it hasn't passed the evnt horizon.
What is the force of gravity at Pluto's surface on an object with a mass of 100 kg?
The force of gravity on an object with a mass of 100 kg at Pluto's surface would be approximately 6.7 N. Gravity on Pluto is only about 0.063 times that of Earth's gravity, so objects weigh much less on Pluto.
What force always acts in the opposite direction from gravity?
The normal force, exerted by a surface in contact with an object, always acts perpendicular to the surface and in the direction opposite to gravity to keep the object from falling through the surface.
Why does an object accelerate when it falls to Earth's surface?
beause of gravity
