Gravity

When an elevator starts or stops, there is a change in acceleration which causes a shift in forces acting on your body. This sudden change can make you feel a jerk as your body adjusts to the new motion. It's similar to the sensation you feel when a car accelerates or decelerates quickly.

A nebula IS a cloud of dust and gas loosely held together by gravity.

In "Pine Quest" on Gravity Falls, the goal is to complete various quests and puzzles to progress through the game. To win, you need to explore the different locations, interact with characters, and solve challenges along the way. Keep playing and advancing in the game to reach the end and complete the final quest.

A spring scale or a dynamometer is typically used to measure the force or pull of gravity acting on an object.

Buoyancy. This is the force exerted by a fluid on an object. It is due to pressure difference in the fluid (pressure increases a you get deeper). Thus the force always acts in the opposite direction to gravity (upward).

The buoyancy force is equal to the WEIGHT of the fluid displaced by the object. Remember that weight is the FORCE due to gravity, and so buoyant force can vary if gravity varies.

The formula for calculating buoyant force is:

F = ρgV

where ρ is density of fluid and V is volume of fluid displaced.

Notice that ρ (density) times V (volume) is mass, and that mass times g (acceleration of gravity) is weight.

Also for your consideration...

An object will rise if buoyant force exceeds weight, like a balloon full of helium (gases like air are also fluids). If weight exceeds buoyancy, the object will sink, like a stone in water.

Weight can also be calculated like buoyancy:

W = ρgV

ρ is density of the object and V is volume of object.

So determining whether an object in a fluid will sink or rise can involve comparing density of fluid with average (bulk) density of object.

If the object is a solid object with known density you can detarmine if object will float our not. If density of object is greater than density of fluid it will sink, and vice versa.

False. The presence of gravity does not directly affect the amount of gas in an atmosphere. Factors such as temperature, pressure, and chemical reactions play a larger role in determining the composition and amount of gas in a given atmosphere.

A pendulum can swing through any angle you want. But because of the

mathematical approximations you make when you analyze the motion of

the pendulum, your predictions are only accurate for a pendulum with a

small arc.

The force of gravity is what pulls liquids towards the ground. Gravity is the natural force that attracts objects with mass towards each other, which is why liquids flow downward and are pulled towards the Earth's center.

If there's any difference, it's the result of air. If you pump all the air out of a

long tube and then drop things in it, they fall with the same acceleration, and

they hit the bottom at the same time with the same velocity. Doesn't matter

if you use a feather, a sheet of paper, a leaf from a maple tree, or a rock.

The acceleration due to gravity is a property of the Earth's mass and radius,

and of gravity itself, and doesn't depend on which way something is moving.

-- The acceleration produced by a force is always in the direction of the force,

and the forces of gravity act along the line between the centers of two objects.

-- One force of gravity acts on the body that's up in the air, pulling it ... and

therefore accelerating it ... toward the center of the Earth, with acceleration

equal to the body's weight/the body's mass = 9.8 meters per second2.

-- The other force of gravity acts on the Earth, pulling it ... and therefore

accelerating it ... toward the center of the body that's up in the air, with

acceleration equal to Earth's weight/Earth's mass. In order to calculate that

number, you have to know the Earth's weight. It's the same as the weight

of the body that's up in the air, since the forces of gravity are equal in both

directions. So once you know the weight of the body on Earth, you know the

weight of the Earth on the body, and you can calculate the Earth's acceleration

when they're falling toward each other.

Yes, gravity is a force that pulls objects toward the center of the Earth. This force is what keeps us grounded and gives weight to objects.

Occasionally, an accident is the result of mechanical failure. But most often, usually,

and typically, accidents are direct results of the fact that the vehicles are under the

manual control of human beings.

Yes, gravity is a force that pulls objects toward each other, so it typically pulls objects down toward larger masses like the Earth. However, in space, the gravitational forces between objects can pull them in various directions depending on their positions and masses.

The forces of gravity always pull two objects toward each other.

Gravity applies to a force between celestial bodies and to the force of gravity pulling something towards it center on the surface of a planet, for example. Electronics is a subfield of electrical engineering and a thing or a gadget can be constructed and designed by using electronics. Magnetism and electromagnetism is not the same thing although it is closely related. Electromagnetism is created by artificial means by having a current flows through a simple wire or other kind of conductor. The force of the magnetism is then increased by winding a length of wire around a coil or a tube. Electromagnetism also happens naturally, for example in the interaction of physical matter in stars such as the sun. When a current is applied to a coiled wire, then electromagnetic waves are created. Magnets can be natural or made from alloys, metals can be magnetized so they have a south and a north pole. Common to all magnets is that they have a magnetic effect, that is to say, they will have a pulling force towards other metals especially iron and steel. Things that have gravity are planets, magnets have magnetism and electronic devices have electronics.

In a free-falling elevator, both you AND the elevator are falling at the same rate of acceleration with respect to the gravitational pull of the Earth. Therefore, since both you and the elevator both accelerate at the same rate, making your velocities increase at the same rate, and you both start off with the same initial velocity, you both travel at roughly the same velocity relative to each other during the entire descent, meaning that your head should not hit the roof of the elevator at any point.

Gravity does not effect speed of light ,so velocity is constant. Even if it effect the effect is negligible. So in short answer is 3*108ms-1

Roots respond to gravity through a process known as gravitropism. When a root detects the pull of gravity, it will grow downward in response. This allows the root to anchor itself in the soil and seek out water and nutrients more effectively.

The law of floatation states that an object will float in a fluid if the weight of the fluid it displaces is equal to its own weight. This principle is based on Archimedes' principle, which explains the buoyant force acting on an object in a fluid.

The center of gravity on a plastic ruler would typically be located at the midpoint, which is where the ruler balances evenly when placed on a narrow edge or fulcrum. This point is usually at the 15 cm mark on a 30 cm ruler or at the 6 inch mark on a 12 inch ruler.

Ignoring gravity can result in not understanding the forces acting on objects, leading to incorrect predictions about motion and interactions. It can also result in unsafe practices, for example, not securing objects or structures properly, leading to potential accidents or damage.

Because the vapor is less dense than the air in which it's floating, so the buoyant

force on it is stronger than its weight.

Exactly the same way that a bar of soap or a rubber ducky moves upward through

a bathtub full of water and against the gravity

Since Jupiter has 317 times the mass of Earth, its gravitational attraction at any given distance is also 317 times greater. On the other hand, the surface gravity (please note that Jupiter doesn't have a proper "surface", though) is approximately 2.5 times that of Earth.
