This is often described as "the acceleration due to gravity". Is this really the best thing to call this? No. A better name would be "the local gravitational field" and list it in units of: ...

No, the acceleration due to gravity is constant. Providing the object does not build up too much speed and air resistance is not a factor the acceleration measured should be the same.

It changes due to different densities of the local Earth. In spite of this, a value of 9.81-ish N/kg is pretty reasonable. And yes, 9.81 N/kg has the exact same units as 9.81 m/s 2 .

Those three types of acceleration — gravitational, linear, and rotational — are the only ones we have that will have the effects of gravity. Which is a big, big problem aboard a spaceship.

We call this g (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 ...

Drag (air resistance) opposes acceleration due to gravity. In a vacuum, such as on the Moon, both objects will hit the ground at the same time. How does gravity work?

Two different types of atoms had the same acceleration within about a part per trillion, or 0.0000000001 percent, physicists report in a paper in press in Physical Review Letters.

In the case of gravity, as far back as around 500 BCE the Ionian Greek philosopher Heraclitus theorized on the balance created by what we came to call ‘gravity’.

In addition, gravity is weaker at the equator due to centrifugal forces produced by the planet’s rotation. It’s also weaker at higher altitudes, further from Earth’s centre, such as at the ...
