Gravitational Constant The gravitational constant (G) is a fundamental constant in physics that describes the strength of the gravitational force between two objects. It has a value of approximately 6.67430(15) x 10-11 Newtons (m2/kg2). Gravity and Everyday Objects The gravitational attraction bet...
How to measure magnetic field strength of a magnet. Why is the magnetic force perpendicular to the magnetic field? What are two ways that magnetism is produced? How do neutral particles move in a magnetic field? Is electromagnetism the same as electricity and magnetism?
What unit is used to measure electrical force? What can affect the strength of gravitational force? A very long straight wire has charge per unit length 1.51 x 10^-10 C/m. At what distance from the wire is the magnitude of the electric field equal to 2.50 N/C?
Hyperdrive or spatialjump, right or wrong, there's at least one theory. But there are some things:Einstein's general theory of relativity predicts that gravitational waves cantravel at the speed of light in a vacuum; Carrying energy and informationrelated to the source; It's the transverse wa...
The two forces are equal in strength and oriented in opposite directions. Many people have trouble visualizing this law because it's not as intuitive. In fact, the best way to discuss the law of force pairs is by presenting examples. Let's start by considering a swimmer facing the wall ...
electrical current is the flow of moving charges in the flow of electrons. Charges move under the influence of an electric field. Just as objects with mass tend to be accelerated by gravitational fields, charged particles tend to be accelerated by electrical fields. The strength of these fields...
It’s difficult, if not impossible, for any company to be truly and fully regenerative today. But it’s possible — and imperative — to begin the smaller transformations which will result in a big transformation, both in the company and outside it. This is the beg...

Add just the right amount of powder and impart just the right velocity to the ball, and it will travel completely around the planet, always falling in the gravitational field but never reaching the ground. In October 1957, the Soviets finally proved Newton correct when they launched Sputnik 1...
