Gravity

Gravity causes small objects to be pulled towards larger objects, such as the Earth. The force of gravity is directly proportional to the mass of the objects and the distance between them, so small objects experience a weaker gravitational force compared to larger ones. This force is what gives small objects weight and keeps them grounded.

FSL stands for Free Surface Level. In a gravity canal, the FSL is the level of the water surface that is free to interact with the atmosphere and not confined by any structure. It indicates the height at which water is flowing in the canal.

The measure of the pull of gravity on an object is its weight, which is determined by the mass of the object and the acceleration due to gravity. The acceleration due to gravity varies on different planets, so the weight of an object will change if it is on a planet other than Earth.

The force of gravity between two objects is determined by their masses and the distance between their centers. The larger the masses of the objects and the smaller the distance between them, the greater the force of gravity.

A quarter and and a pencils have little air friction and would not observed to fall at different velocity in normal classroom condition. It will be observed to fall to the ground at the same time.

If you increase the mass, you increase the gravitational force proportionally.

If you increase the distance between two masses, you decrease the gravitational force between them by and amount proportional to the square of the distance.

no a body can,t be rotate about its centre of gravity

Plants can contribute to weathering by a tree growing in the cracks of a rock then its roots will eventually run out of room therefor it pushes steadily against the rock until it breaks and so on.

It is very well known that Issac Newton was said to be the first to discover gravity while walking through his estate one day and saw an apple fall from a tree. He then asked, "If an apple falls from a tree, does the moon also fall?" He then created calculus, which was originally created to calculate the speed of a falling moon. So in short, Issac Newton.

Gravity acts as a centripetal force when it pulls an object towards the center of rotation in a circular motion, keeping the object moving in a curved path instead of a straight line. This allows the object to continually change direction without breaking away from the circular path, achieving dynamic equilibrium.

Force equals mass times acceleration, if you are sitting at rest you are not accelerating, so your acceleration is zero.

The force is your mass times zero, 75 kg x 0 ms-2= 0 newtons.

If the force is zero, this means the force of gravity pulling you down is cancelled out by the force of the chair pushing you up.

So the forces are balanced.

Gravity is both a theory and a law. The theory of gravity, proposed by Isaac Newton, explains how objects with mass attract each other. The law of gravity, also known as the law of universal gravitation, quantifies this force of attraction between objects with mass.

Weight is what we call the amount of the gravitational force between the Earth

and an object on the surface of the Earth.

It works both ways. Your weight on the Earth is also the Earth's weight on you.

To calculate the effect of gravity on weight, you multiply an object's mass by the acceleration due to gravity. The formula is W = m * g, where W is weight, m is mass, and g is the acceleration due to gravity (9.81 m/s^2 on Earth). The result will be in units of force (e.g. Newtons).

The value of 3g would be three times the acceleration due to gravity (g). On Earth, the average value of g is approximately 9.81 m/s^2, so 3g would be 3 * 9.81 = 29.43 m/s^2.

If the mass of one or both objects were increased by a factor of four, the force of gravity between them would be four times greater. The force of gravity is directly proportional to the product of the masses of the two objects.

In "Gravity Falls," Tara Strong voices additional characters in some episodes, including a few unnamed characters such as Citizen #2 in "Boyz Crazy" and Scientist #1 in "Society of the Blind Eye."

Examples of conservative forces include gravity, electromagnetic force, and spring force. These forces depend only on the initial and final positions of an object and do not dissipate energy as the object moves along a path.

If gravity increases, the bridge is subjected to more weight. If gravity decreases, the bridge is subjected to less weight. Either way, the bridge will have a maximum weight that will remain the same regardless of the gravitational environment.

On Venus, the acceleration due to gravity is about 8.87 m/s^2. Since weight (in newtons) is equal to mass (in kg) multiplied by acceleration due to gravity, the weight of 1 kg on Venus would be 8.87 newtons.

What we call "gravity" is a fact of nature that causes forces of attraction in both

directions between every two specks of mass, no matter where they are or what

else is in between them. The forces are stronger if the masses have more mass,

and if they're closer together.

That's the connection between gravity and the force of it.

(The force of gravity is not the only force there is. Force can also be generated

by a muscle in your arm, an electrical charge on a rubber balloon, a bottle rocket,

a horse, wind, a gasoline engine, flowing water, a stretched rubber band, etc.)

The vertical motion of a projectile is affected by gravity. Gravity acts to accelerate the projectile downward while it is in motion, causing its vertical velocity to increase or decrease accordingly.

Gravity affects the vertical component of projectile motion by causing the object to accelerate downward as it moves horizontally. This acceleration due to gravity affects the object's vertical displacement and velocity. It does not affect the horizontal component of projectile motion, which moves at a constant velocity in the absence of air resistance.
