Which statement is true according to Newton’s law of universal gravitation?
Newton’s law of universal gravitation is usually stated as that every particle attracts every other particle in the universe with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.
How does Newton’s law relate to gravity?
Newton’s Law of Gravity says that gravity is a force that acts between any two objects with mass, and that force increases if the mass increases and decreases if the distance between the two objects increases. This force is always attractive, that is, it always works to pull the objects closer together.
What is true gravitational force?
The gravitational force only acts between very, very massive objects. … The gravitational force acting upon an object is the same as the weight of the object. The gravitational force between two objects is independent of the mass of the smaller of the two objects.
What is gravitational force equal to?
On the Earth this gravitational force is known as weight. The gravitational force is equal to the product of the mass and the gravitational field strength.
Which is larger the sun’s pull on Earth or Earth’s pull on the sun?
Which is larger, the Sun’s pull on Earth or Earth’s pull on the Sun The Sun’s pull on Earth is twice as large as Earth’s pull on the much larger Sun. They pull on each other equally.
Which statement is true about Newton’s first law of motion quizlet?
What is Newton’s First law of motion? An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
What is the law of gravity in simple terms?
a law stating that any two masses attract each other with a force equal to a constant (called the gravitational constant) multiplied by the product of the two masses and divided by the square of the distance between them.
How did Einstein explain gravity?
GETTING A GRIP ON GRAVITY Einstein’s general theory of relativity explains gravity as a distortion of space (or more precisely, spacetime) caused by the presence of matter or energy. A massive object generates a gravitational field by warping the geometry of the surrounding spacetime.
What are the 3 laws of gravity?
Newton’s three laws of motion may be stated as follows:
- Every object in a state of uniform motion will remain in that state of motion unless an external force acts on it.
- Force equals mass times acceleration [ ].
- For every action there is an equal and opposite reaction.
Where is gravity strongest?
In the case of the earth, the force of gravity is greatest on its surface and gradually decreases as you move away from its centre (as a square of the distance between the object and the center of the Earth).
Is gravity just a theory?
Gravity is most accurately described by the general theory of relativity (proposed by Albert Einstein in 1915), which describes gravity not as a force, but as a consequence of the curvature of spacetime caused by the uneven distribution of mass.
Who invented gravity?
What is value of G?
Its value is 9.8 m/s2 on Earth. That is to say, the acceleration of gravity on the surface of the earth at sea level is 9.8 m/s2. When discussing the acceleration of gravity, it was mentioned that the value of g is dependent upon location. There are slight variations in the value of g about earth’s surface.
What is gravity made of?
They proposed that gravity is actually made of quantum particles, which they called “gravitons.” Anywhere there is gravity, there would be gravitons: on earth, in solar systems, and most importantly in the miniscule infant universe where quantum fluctuations of gravitons sprung up, bending pockets of this tiny space- …7 мая 2014 г.
