According to Sciama's interpretation of Mach's principle, when a body of mass m moves with acceleration 伪 relative to a second mass M , the latter experiences a force of the form F = GmM 伪/ c 2 r, where G is the gravitational constant, c is the speed of light, and r is the...

Gravitational mass is the property of objects that determines how they interact via gravity. For example how the Moon rotates around Earth. Inertial mass is an object's property that determines how much the object "resists" acceleration when force is applied to it. And it seems both are one ...
where m is an object's mass, and g is the acceleration due to gravity. Acceleration due to gravity on Earth, is 9.8 m/s² — it never changes, regardless of an object's mass. That's why if you were to drop a pebble, a book and a couch off a roof, they'd hit the ground ...
Gravity is a force. It pulls objects with mass toward each other. The moon has less gravity than Earth. This means it does not pull on things as strongly. For example, let's say that an astronaut drops something...
(lower case), the "acceleration due to gravity." This is the famous legend that has Galileo dropping objects from the Leaning Tower of Pisa. It tells us that the gravitational force is proportional to the mass of the object. This is such an important discovery that physicists call it a [...

aThe earth's gravity field is almost the same as that of a sphere having the same average radius and total mass but increases slightly towards the poles. In gravity surveys, gravimeter measures gravity differences ,not absolute field strengths. 地球的引力场轻微地几乎是相同象那球形有同样平均半径...
What exactly presents the Einstein equation for gravity? Why is it important to precisely know acceleration due to gravity? Why might you need to divide mass by gravity? Explain what is a pseudo force? Include an example. Explain the difference between inertial and gravitational mass. If these ...
