Gravity

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.

The specific gravity of powdered sugar is approximately 0.6 to 0.8.

Newton's law of gravity states that the force of gravity between two objects is directly proportional to the product of their masses and inversely proportional to the square of the distance between them. Acceleration due to gravity near the Earth’s surface is approximately 9.81 m/s^2.

To use gravity in an egg drop experiment, simply drop the egg from a certain height and observe how gravity affects its descent. You can vary the height from which you drop the egg to see how it impacts the egg's landing. Consider using different materials or design structures to protect the egg from the force of gravity upon impact.

The value for acceleration of gravity was discovered by Sir Isaac Newton in the late 17th century. He determined that the acceleration due to gravity near the surface of the Earth is approximately 9.81 m/s^2.

The center. just a theory its really hard to say things about a black hole because we know so little about them other than they are made from supernovas and have an intence gravitational pull and consume everything around it and its so dence not even light can escape it (thus the name black hole)

The center of gravity using the plumb line method is determined by suspending an object from different points and allowing it to come to rest. The intersection of the lines traced by the plumb bob at each resting position indicates the center of gravity of the object. This method is commonly used to locate the center of gravity of irregularly shaped objects or structures.

The acceleration due to gravity alone on Earth

is about 9.81 meters per second-squared.

Two forces that can work against gravity are lift (such as in the case of a plane generating lift to counteract gravity) and buoyancy (such as in the case of a buoyant object in water being pushed upwards).

To calculate the center of gravity of a pipe, you will need to determine the geometric center of the pipe's cross-section. This is typically done by finding the midpoint of the diameter for a circular pipe cross-section. Next, consider the material density distribution within the pipe to pinpoint the location of the center of gravity. The final center of gravity position will be a balance point where the pipe can be considered to be concentrated.

The effect of gravity slowing down blood flow from the legs to the heart is counteracted by the contraction of leg muscles, which act as pumps to push blood upward through the veins. Additionally, one-way valves in the veins prevent blood from flowing backward and help maintain the flow of blood toward the heart.

Yes, gravity is a fundamental force of nature that affects objects with mass. Objects with mass are attracted to each other due to gravity, creating phenomena such as planetary motion and the acceleration of falling objects.

Mass remains the same when gravity changes, while weight changes. Mass is a measure of the amount of matter in an object and remains constant regardless of the gravitational force acting on it. Weight, on the other hand, is the force of gravity acting on an object's mass and will change with variations in gravity.

When gravity changes, the mass of an object remains the same. However, its weight would vary depending on the strength of gravity.

Gravity remains constant regardless of the direction you are driving in. However, the gravitational force may feel stronger when driving uphill due to the incline causing a greater component of gravity to act against the vehicle's motion.

When driving uphill, gravity acts against your motion, decreasing your kinetic energy. When driving downhill, gravity acts in the direction of motion, increasing your kinetic energy.

Gravity is a non-contact force, meaning it can exert its influence on objects without direct physical contact between them. This force is responsible for the attraction between all objects with mass.

The center of gravity in the body is typically located around the belly button. Maintaining good posture, such as standing up straight with shoulders back, helps align the body so that the center of gravity is well-supported. This reduces strain on muscles and bones, promoting balance and stability.
