All physical objects, he said, had a force of attraction between them, the strength of the force depended on the masses of the objects and the distance between them.

What distance is a book from the floor if the book contains 98 joules of potential energy and has a mass of 10kg?
The idea here is to write the equation for gravitational potential energy:GPE = mgh (mass x gravity x height), then replace the numbers you know, and solve the resulting equation. You can assume Earth's gravity to be about 9.8 newtons/kilogram.
What gave Sir Isaac Newton the idea about gravity and when?
when he was watching a apple fall off a tree into an orchard. It gave him an idea to start to study gravity.
How do gravity and inertia work together in the solar system?
The Earth's gravity is trying to pull the Moon towards the Earth. However, the Moon has inertia. It is trying to move in a straight line. If the Moon had no "sideways" velocity it would fall onto the Earth. In fact the Earth's gravity is needed just to bend the direction of the Moon's path and make the Moon orbit the Earth instead of flying off into space. This becomes clear if you do the mathematics, but that's the basic idea.
Did Einstein create a telescope?
No, he did not. But his theories are supported by some interesting observations that are indirectly related to telescope technology. Under special circumstances, like the occurance of a total solar eclipse, it can be shown that the light from stars that are behind the sun actually bends under the influence of the sun's gravity, and the stars can be seen from earth. Also, very large objects in distant space like super giant galaxies can have a similar effect on objects behind them, almost as if the farther objects are being seen through a gravity telescope. So Einstein's idea that light is influenced by gravity is well established.
How many newtons are on a scale of 5 newtons?
the two quantities are different - 5kg indicates the mass of the object, ie how much stuff it contains, a newton is a force, in this case a weight (a force produced by gravity, the mutual attraction of two objects with mass). The weight produced by 5kg depends on g, which is a function of how massive the other object is and how far away you are from its center. Assuming you mean 'how many newtons is 5kg on the surface of earth', g is about 9.81. To get the weight (in newtons) from the mass (in kg) all you do is multiply by g - so 5kg by 9.81 roughly equals 49 newtons. The apparent weight may be less than this. If you only want a rough estimate, then if we approximate the g from 9.81 to 10, then the force (in Newtons) is almost equal to the mass (in kg) multiplied by 10. Therefore 5kg is almost 50N (but actually less than 50). It is not accurate but it gives you an idea of the magnitude.
What is the basic idea behind decentralization?
kundanThe basic idea behind decentralisation is that there are a large no. of problems and issues which are better settled at local level.
What is the basic idea behind hydraulics?
The incompressibility of most liquids.
What is the basic idea behind hydraulic machines?
The incompressibility of most liquids.
What is the basic idea behind T.S. Eliot's crticism of hamlet?
It is an artistic failure.
What is the basic idea behind rule of law?
To achieve order and maintain it, in society.
What is isacc newton famous for?
I would say Issac Newton is best known for getting hit in the head with an apple and coming up with the idea of gravity. Newtons 3 laws
How are mass and gravity different?
Mass is what causes gravity. Better do some reading on mass, and on gravity; the difference will be quite clear. Those are not two things that you easily confuse, once you get the basic idea.
What is 105 pounds in newtons?
The pound is a unit of weight, which is the force that gravity exerts on an object on earth's surface, and the newton is a unit of force defined metrically. Since weight is the result of an object's acceleration by the force of gravity (yes, the idea of acceleration applies to a stationary object), they are directly comparable. One pound [of force] equals 4.44822162 newtons, so 100 pounds equals 444.822162 newtons. For any object in one frame of reference for all measurements, pounds and newtons can be converted one to another in this way.
What important discovery was made by edmond halley and alexis clairaut using newtons idea of mathematics and gravity?
They were able to find the orbit of a comet and predict the year of it's return.
What is the magnitude of the force of gravity on the skydiver with 845 N?
If you're telling us that the skydiver weighs 845 newtons, then that's the magnitudeof the forces of gravity between him and the Earth whenever he's near the Earth.
What was the basic idea behind roosevelts plans for recovery?
Why don't you read the Chapter or the new deal? Duffer
How does a nebula form into a prostar?
The basic idea is that it is pulled together by its own gravity. For more details, check the Wikipedia article on "protostar".
