Gravity

To increase gravity, you would need to increase the mass of the object or planet exerting the gravitational force. To decrease gravity, you would need to reduce the mass of the object or planet exerting the gravitational force. Another way to decrease gravity is by increasing the distance between the objects experiencing the gravitational force.

In the context of celestial bodies, gravity is greater on larger objects with more mass. For example, Earth's gravity is greater than the moon's gravity due to Earth's larger size and mass.

Gravity depends on the mass of matter. The larger the mass, the greater the gravitational force it exerts.

No, gravity and buoyancy are not the same thing. Gravity is the force of attraction between objects with mass, while buoyancy is the upward force exerted by a fluid that opposes the weight of an immersed object. Buoyancy depends on the density of the fluid and the volume of the object, while gravity depends on the mass of the objects involved.

No it isn't it is in kg/oz/ect

Weight is a force equal to the product of an object's mass and gravity. Gravity in this context is not a force but an acceleration. Near the Earth's surface, that acceleration is 9.8 m/s², regardless of the mass.

Gravity is a force that exists between any two objects with mass, and it acts over a distance. It is proportional to the masses of the objects and inversely proportional to the square of the distance between them, as described by Newton's law of gravitation.

Newton confirmed his hypothesis about gravity by developing the Universal Law of Gravitation, which described the force of gravity between two objects. He used this law to predict the motion of the planets and the Moon, which matched observations made by astronomers, confirming the validity of his theory.

The Earth pulls down on you, but you pull up on the Earth!

Bouncing on a trampoline does not affect gravity itself. Gravity still exists and exerts the same force on you whether you are on a trampoline or not. However, the trampoline provides a surface that can help you overcome gravity's pull temporarily, allowing you to experience the sensation of jumping higher than you could on solid ground.

No, the water inside the mug won't appear lighter. The perceived weight of the mug may seem less due to the buoyant force acting on it in water, but the water itself won't change its color or weight when viewed inside the mug.

None

Gravity is the dominant force that governs motion in the universe on a large scale, such as the motion of planets, stars, and galaxies. It is responsible for keeping celestial bodies in their orbits. On a smaller scale, other forces like electromagnetism and nuclear forces also play a role in governing motion.

Gas does not have a flat surface due to gravity. Gas molecules are constantly moving in all directions, leading to a more random and spread-out distribution. Gravity does play a role in keeping gas molecules bound to Earth, but it does not affect the shape of the gas itself.

Look up the gravitational acceleration, in meters/second square, for example in the Wikipedia article about "Mars". Meters/second squared is the same as newtons/kilogram.

The only factor needed to calculate change in velocity due to acceleration of gravity is time. The formula to calculate the change in velocity is: change in velocity = acceleration due to gravity * time.

Because of Newton's 3rd law, if you push on a wall with, let's say, 10 N, the wall will, by definition of the law, push back on you with 10N. The forces are balanced and you don't move backwards because the forces "cancel out" because they are equal and opposite, and if Fnet=0, we now acceleration must be 0.

The speed of an object in a specific direction is referred to as velocity. It is a vector quantity that includes both the speed and direction of motion. Velocity indicates how fast an object is moving and in which direction.

The amount of matter in an object is called mass, and it is a measure of the inertia of an object. Mass is a fundamental property of an object that quantifies how much matter it contains, influencing its resistance to acceleration or change in motion.

Velocity is distance/time. So, 2000/400 reduces to 5 m/s, but since velocity is a vector, direction MUST be stated along with the speed we just calculated. The final answer is 5 m/s South (or 270 degrees).

The acceleration of gravity is important because it determines the rate at which objects fall towards the Earth. It affects a wide range of physical phenomena, from the motion of projectiles to the orbits of planets. Understanding and being able to calculate the acceleration of gravity is essential for various scientific and engineering applications.

Gravity, pressure, and temperature are all related in the context of a planet's atmosphere. Gravity determines the pressure of the atmosphere, with higher gravity leading to higher pressure. Temperature affects pressure as well, with increasing temperature leading to higher pressure due to the increase in kinetic energy of gas molecules. Overall, these factors work together to create the atmospheric conditions we experience on Earth and other celestial bodies.

Yes, in a sloppy manner of speaking. A better way to say it

is that gravity is a property of mass and space that causes

forces of attraction between every pair of masses.

Yes. Gravity is a fundamental force that is the attraction between any object. It has nothing to do with pressure or gases.

Note that while some people may explain that it acts between two masses, and while this is true, it also affects light particles which have no mass.

Currently gravity is described as an effect on the space-time-continuum. Just imagine a heavy ball on a trampoline, but in 3D space rather than the 2D surface of the trampoline. A body with mass will create a sort of 'dip' in space which an object will fall into, including light.

are you talking about sub atomic particles ? and do you agree that outer space is a vacuum ?

and so what holds us to earth ? Earth has it's own atmosphere and the pressure inside that atmosphere is what holds us to Earth ! It is not magnetism !

Now as we venture into space , we ask what are "Black holes"

To understand this , we must think of outer space, as Flat !!

Then we can bigin to understand the Paradox of "Black Holes"

Acceleration is the rate of change of velocity over time. In the context of gravity, objects near the Earth's surface experience a gravitational acceleration towards the center of the Earth of approximately 9.81 m/s^2. This gravitational acceleration causes objects to fall towards the Earth at an increasing rate due to the force of gravity acting upon them.
