Gravity

If gravity and friction have no influence, the rock would continue moving in a straight line at a constant speed due to its inertia. It would not slow down or change direction unless acted upon by an external force.

Gravity impacts different objects based on their mass and distance from a gravitational force. Objects with greater mass experience a stronger gravitational pull, causing them to attract other objects towards them. The force of gravity weakens with distance, so objects farther away experience less gravitational pull. Generally, gravity causes objects to be pulled towards each other, affecting their motion and interactions in the universe.

The "why" is sort of tricky. You can think of every mass exerting a force on every other mass. According to General Relativity, a mass will actually distort spacetime in its surroundings, in such a way that this affects other masses.For more details on what we know and what we don't know, you may want to look up "Gravity" in Wikipedia, for example.

It is incorrect to say that if a root is placed horizontally it will bend towards gravity because roots exhibit positive gravitropism, meaning they grow downwards in response to gravity. Thus, a horizontal root would still grow downwards due to gravitropism.

Gravity ! The source (or start) of a river is (usually) high up in a mountain or hill. As the water travels downhill, it combines with others - gradually widening and gathering pace.

Mass is a measure of the amount of matter in an object, while weight is the force exerted on that object due to gravity. The weight of an object is directly proportional to its mass and the acceleration due to gravity, as given by the formula: weight = mass x acceleration due to gravity.

Gravity affects diving by pulling the diver towards the earth, increasing the pressure on the body the deeper they go. This pressure affects the compression of gases in the body, potentially causing issues such as nitrogen narcosis or decompression sickness. Additionally, gravity affects buoyancy, making it harder for divers to stay afloat and control their position underwater.

The force produced by gravity acting on a mass is known as weight. Weight is calculated as the mass of an object multiplied by the acceleration due to gravity. This force is proportional to the mass of the object and the strength of the gravitational field.

Gravity is not a form of speed but a force that attracts objects with mass towards each other. The speed at which an object falls towards the Earth due to gravity is approximately 9.8 meters per second squared, which is known as acceleration due to gravity.

The WEIGHT is the measure of the force of gravity on an object (including people).weight = mass x gravitational field

The gravitational field near Earth's surface is approximately 9.8 newton/kilogram.

Use the formula v2=u2+2*a*s

v=final velocity

u=intital velocity

a=acceleration due to gravity

s=displacement

This then gives:

2*9.8*5

=98

square root of 98

9.89ms-1

No. Magnets behave like any other mass in relation to gravity.

Possibly. Spinning superconductors produce not only a weak magnetic field, the so-called London moment but an angularly accelerated superconductive ring also induces non-Newtonian gravitational fields in its neibourghood. It has been postulated by Tajmar and de Matos that the force carrying particles of both the electromagnetic force and gravity gain mass under such conditions. The effect has been named the gravitomagnetic London moment. (Credit ESA)

The law of gravity is the same everywhere because it is a fundamental force of nature that acts uniformly on all objects with mass. This consistency across the universe is a reflection of the underlying nature of space and time as described by the principles of physics.

The combined center of gravity is formed by the individual centers of gravity of all the objects that are combined or connected together. It is calculated by taking into account the mass and position of each object to determine the overall center of gravity of the entire system.

1. In a weightless environment, such as outer space, objects are not pulled towards each other by gravity.
2. Objects floating in water due to buoyancy are not examples of gravity at work.
3. The motion of planets due to their inertia rather than the gravitational force between them is a non-example of gravity.

Gravity pulls objects toward the center of the Earth, causing them to accelerate as they fall. This acceleration increases their speed until they reach the ground or another surface.

"Negative gravity" is not a scientific concept. Gravity is a fundamental force of attraction between masses. "Positive gravity" is simply the normal gravitational force experienced on Earth, pulling objects towards the center of the planet.

One question that a lab might be trying to answer is: What is the effect of temperature on enzyme activity? This type of experiment would involve testing how changes in temperature impact the rate of enzyme-catalyzed reactions in a controlled setting.

The gravity model is an economic concept that predicts the interactions between two places based on their size and distance from each other. It suggests that larger economies or populations and shorter distances between them will result in stronger economic relationships, such as trade or migration flows. The model is commonly used in international trade and migration studies to understand patterns of interaction between countries or regions.

The balance of buoyancy and gravity is called equilibrium. It occurs when the upward force of buoyancy on an object is equal to the downward force of gravity acting on it, resulting in a state of balance or stability in a fluid.

The amount of gravity acting on an object is determined by its mass. The greater the mass of the object, the stronger the force of gravity acting on it. Gravity is a force that pulls objects towards each other, with the strength of the force depending on the masses of the objects and the distance between them.

While gravity is not considered a typical stimulus that induces tropic responses in plants, it does play a role in some plant behaviors like gravitropism (response to gravity). Gravitropism causes plant roots to grow downward and stems to grow upward, helping plants orient themselves for optimal growth. Other stimuli, like light, touch, and chemicals, are more commonly associated with inducing tropic responses in plants.

The specific gravity of Shell Argina S6 cylinder oil is approximately 0.921 at 15.6°C.

The specific gravity of emulsion polymer can vary depending on the specific type and composition of the polymer. However, generally, the specific gravity of emulsion polymers range from 1.0 to 1.2.
