Gravity

Force is the first derivative of energy. The gravitation energy is

W = -mGm/r + cmV = -mvh/r + cP

Gravity energy is a Quaternion energy consisting of a scalar force -mGM/r and a vector energy cmV = cP a momentum vector energy, the so-called Dark Energy.

In addition physics does not recognize the four space derivative X,properly a Quaternion derivative, X =[d/dr, DEL].

With these reflections the Force is the first derivative and a Quaternion Force.

Force F= XW = [d/dr, DEL][ -vh/r ,cP]

F = [vh/r2 -cDEL.P, cdP/dr -DEL vh/r + cDELxP]

F = [vp/r - cp/r cos(P), -cp/r 1P + vp/r 1R + cp/r sin(P) 1RxP]

F = cp/r[v/c -cos(P), -1P + v/c 1R + sin(P) 1RXP]

cp/r = cp/ct=p/t = mv/t = ma.

The vector energy provides the centrifugal force that keeps the mass m from falling into the center. The centrifugal force is teh Divergence of the vector energy, cDEL.P = -cp/r cos(P).

It isn't quite clear what you mean. Depending on the context, gravity is either expressed as a force (measured in newton), or as a field (measured in newton/kilogram), so you can't compare it directly with a mass.

The pen is at rest as long as it is not moving relative to its surroundings. If the pen is stationary, it is considered to be at rest.

It's forced upwards by the pressure of the blood behind it. Additionally, there are valves in veins and arteries to stop the blood flowing backwards (kind of like a door that only opens one way).

The unit of acceleration is Length/Time2 .

It depends on how great the gravitational gradients are. Gravity follows the Inverse square law, so The gravitational attraction force between two point masses is directly proportional to the product of their masses and inversely proportional to the square of their separation distance . The force is always attractive and acts along the line joining them.(Wikipedia says this but my physics text book confirms, in case you wanted an exact answer) In extreme situations, like that found around stellar mass black holes, the gravitational gradient between say your head and feet is great enough that it will rip you in half, thus killing you. Don't believe me, look up spaghettification :-). In super massive black holes, you have to descend fairly deep into the black hole for the effect to take hold

Splashing around in a bath with low gravity would cause the water droplets to float rather than fall back into the bath. The droplets would likely form hovering globules that could be pushed around easily due to the reduced gravitational pull.

The value of acceleration due to gravity (g) on Earth is approximately 9.81 m/s^2. This value can vary slightly depending on the location on Earth due to factors like altitude and latitude.

Newton's 3 laws of motion:

1.) The law of inertia- An object will remain at rest unless acted on by an unbalanced force. An object in motion will remain in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

2.) Acceleration is produced when a force acts on a mass. The greater the mass (of the object being accelerated) the greater the amount of force needed ( to accelerate it).

3.) For every action, there is an equal but opposite reaction.

The string that the 'bob' hangs from is a fixed length. So when the bob is off center

and over to one side, it must be a little higher than when it's hanging straight down.

The restoring force is the force of gravity that pulls it back down to the center.

Yes, according to our current understanding of physics, the speed of gravity is considered to be constant. It is believed to travel at the speed of light, which is approximately 186,282 miles per second. This means that changes in gravitational fields propagate through space at this speed.

If the force of gravity were to disappear suddenly, the mass of the body would remain the same, as mass is a measure of the amount of matter in an object and does not change. However, the weight of the body would become zero, since weight is the force exerted on an object due to gravity.

The speed of a ball thrown against gravity decreases because gravity acts in the opposite direction of the ball's motion, slowing it down. As the ball goes higher, it loses kinetic energy as it works against gravity, causing its speed to decrease until it reaches its peak and falls back down.

Yes, the gravity on Venus is about 91% of the gravity on Earth. So, a human on Venus would not be significantly squashed by the gravity, but they would feel heavier than on Earth due to the increased gravitational force.

A product with a specific gravity greater than 1 will sink in water. This means the product is denser than water.

To determine if a product will sink in water based on its specific gravity, compare the specific gravity of the product to that of water. If the specific gravity of the product is greater than 1, it will sink. If it is less than 1, it will float. The specific gravity is the ratio of the density of the product to the density of water.

When the distance between two objects is doubled, the strength of gravity decreases to one-fourth of its original value. This is because gravity follows an inverse square law, where the gravitational force is inversely proportional to the square of the distance between the objects.

Gravity is proportional to the product of the masses, and inversely proportional

to the square of the distance. The gravity constant is simply the proportionality

constant.

If you're calculating with all SI units, then the universal gravitational constant is

6.67 x 10-11newton-meter2/kilogram2

As you get further away from Earth, the gravitational forces between you and

Earth decrease. But the gravitational forces between you and something else

might increase, like between you and the moon, or between you and the sun.

The forces of gravity between two masses are always forces of attraction.

As far as we know now, gravity always draws the two masses towards each

other, and never pushes them apart.

There are 5 consonants in the word "gravity" - "g", "r", "v", "t", and "y".

Newton's law of universal gravitation 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. This law helps us understand how the force of gravity between objects changes as their masses change or as they move closer or farther apart.

The center of gravity of the human body is typically located around the pelvis region, specifically near the sacrum. This point is important for maintaining balance and stability during various movements. It varies slightly depending on body composition and posture.

Earth's gravity is the force that objects experience due to the planet's mass. The acceleration due to gravity on Earth is approximately 9.8 m/s^2. This means that objects on Earth experience a gravitational force that is about 9.8 times stronger than in space.

Mass is a measure of the amount of matter in an object, weight is the force of gravity acting on an object due to its mass, and gravity is the natural force of attraction between objects with mass. In simple terms, mass is what an object is made of, weight is the force with which it is pulled down by gravity, and gravity is what causes that force.
