Gravity

Gold has the highest specific gravity out of the options given, as it is a dense metal. Styrofoam has a low specific gravity because it is lightweight and mostly made up of air. Water has a specific gravity of 1, while halite (rock salt) is more dense than water but less dense than gold.

Here we have to be precise with the terms that we use. Gravity is the property of an massive body. Gravitational force is the force between two massive bodies. Acceleration due to gravity is the acceleration produced in a body due to gravitational pull on it. And it is constant at a particular. place and independent of the size , mass and nature of the body. If M is the mass then Mg is the gravitational pull on it. So 80 kg would have a force of gravity = 80 * 9.8 N

That would be called a "constant speed".

(Not 'velocity', since no information about the direction of its motion has been given.)

The name "gravity" comes from the Latin word, gravitas. In the Europe of Newton's time, Latin was the language used by the learned, and many books on academic and scientific subjects were written in Latin so that they could be read by people in all the European countries regardless of the reader's own native language. English is coming to play a similar role in the world today. Gravitas simply meant "heaviness" or "weight," and heavy bodies were usually said at this time to possess the property of gravity. Their heaviness, or weight, was what made them fall down. Newton had new things to say about heaviness, and a new way of talking about it. By saying that gravity should be understood as a force that's exerted between heavy bodies that had what Newton called mass, Newton was saying that weight shouldn't any longer be regarded as simply a property possessed by a "heavy body", but that a body that seems to be heavy is in fact being attracted by another body with mass, in this case, the earth. So it tends to push downwards towards the center of the earth, against anything (such as your hand) that gets in the way to prevent it from falling. When you weigh something, you're measuring how difficult it is to prevent the heavy body from moving downward.

The picture is resting on the shelf, which counteracts the force of gravity pulling it down. The shelf provides support that balances the weight of the picture, preventing it from falling.

The specific gravity of liquid argon is approximately 1.4.

No. Gravity is a function of mass, and since the sun is thousands of times bigger, the sun's gravitational force is abomany thousands of times greater. However, the moon is much closer to earth (a quarter of a million miles vs. 93,000,000 miles for the sun), so the moon's gravitational effect on the earth is much larger than the sun's gravitational effect on the earth.

This is why ocean tides resulting from the moon's gravitational pull are much higher than tides resulting from the sun's gravitational pull. One a month, when the sun and moon are aligned on the same side of the earth, will create the highest tides since the gravitational pull of both sun and moon are pulling in the same direction.

A specific gravity less than 1 allows a chemical to float in water. This means the chemical is less dense than water and so it will float on the water's surface instead of sinking.

The force of gravity on an object with a mass of 100 kg at Pluto's surface would be approximately 6.7 N. Gravity on Pluto is only about 0.063 times that of Earth's gravity, so objects weigh much less on Pluto.

Gravity pulls the projectile down towards the ground, affecting its trajectory. Air resistance acts against the forward motion of the projectile, slowing it down as it travels through the air. These forces must be accounted for when designing and using a catapult for accurate targeting.

The gravity on Mercury is 38% of Earth's gravity. So, if you were 150mlbs on Earth, you would be 57 lbs on Mercury.

Chemical reactions are a topic in chemistry, gravity is a topic in physics, and atoms are a topic in both chemistry and physics.

The force of gravity on an object that needs to be lifted is called the object's weight. This weight is the measure of the force of gravity pulling the object downward towards the Earth.

Gravity is a noncontact force because it acts at a distance without the need for physical contact between objects. This force is exerted between any two objects with mass, pulling them towards each other based on their masses and the distance between them, as explained by Newton's law of universal gravitation.

Capillary action does not defy gravity; it is a result of intermolecular forces, specifically adhesive forces between the liquid and a solid surface, which allow liquids to move against gravity in narrow spaces like tubes or porous materials. This phenomenon occurs because the adhesive forces between the liquid molecules and the solid surface are stronger than the cohesive forces between the liquid molecules themselves.

The acceleration due to gravity on Earth is approximately 9.81 meters per second squared. This means that for every second an object is in free fall near the surface of the Earth, its velocity increases by 9.81 m/s.

by the laws of motion(s=ut+gt2) you can easily find out the answer, where s is the height, u is the initial velocity(in this case its 0), g is the acceleration due to gravity. since u is 0 the equation reduces to s=gt2 the answer is about 3.1 sec

Yes, an increase in mass will lead to an increase in gravitational pull. This is due to the direct relationship between mass and gravitational force as described by Newton's law of universal gravitation.

The specific gravity of lithium is around 0.534 grams per cubic centimeter, which is quite low compared to other metals.

Gravity is called the invisible force because it is a natural phenomenon that cannot be seen by the human eye. It is a fundamental force that attracts objects with mass towards each other, regardless of their size or distance. Although we cannot see gravity directly, we can observe its effects on objects and bodies in the universe.

The only force affecting an object's gravity is the gravitational force, which is determined by the mass of the object and the distance between objects.

Gravity affects motion by exerting a force that causes objects to accelerate towards the center of the Earth. This acceleration influences the direction of motion by pulling objects downward. As a result, gravity can cause objects to fall towards the ground or follow a curved path when in motion.

Lift generated by the wings of an airplane counteracts the force of gravity, allowing the plane to fly. As the plane moves forward, air flows over the wings, creating a pressure difference that results in lift. This force allows the aircraft to become airborne and stay aloft.
