JPG, it works well for output to digital fabrication tools like laser cutters and CNC machines, something we do often at Westside Neighborhood School. Gravit is a simplified version of Adobe Illustrator, not overwhelming but enough to meet the needs for basic graphic design.

There is both a free and a pro version of the program, and the company provides reasonable education pricing upon request. It also provides versions for Windows, Mac, and Linux. Recently, however, with my school’s 1:1 Chromebook program, I needed to find a tool that worked on the web, or at least had a Chromebook extension. Both work sufficiently well for the needs of middle school students. In years past, the free programs of choice were Gimp (replacement for Photoshop) and Inkscape (for Illustrator). As such, I continue to explore less expensive (or free) programs that students can use.

And while I continue to use this professional software suite, it often does not fit a school’s budget when trying to support a 1:1 laptop program. Gravity is keeping it safely in orbit.I have always enjoyed the Adobe Suite for both vector and bitmap graphic design. But until then, we can be satisfied just knowing that planet Earth won't go hurtling into the sun anytime soon. Gravitons or no gravitons, we know that what goes up must come down. And neither have gravitational waves, sometimes called gravitational radiation, which supposedly are generated when an object is accelerated by an external force. Gravitons have never actually been observed, though. One view states that particles called gravitons cause objects to be attracted to one another. Still more-recent theories of gravity express the phenomenon in terms of particles and waves. And two straight paths along that sphere end in a single point. So two objects that were moving along a flat plane are now moving along a spherical plane. It's a curve in space-time.Īccording to Einstein, those objects are still travelling along the straightest possible line, but due to a distortion in space-time, the straightest possible line is now along a spherical path. Einstein also says this occurs due to gravity - but in his theory, gravity is not a force. Newton's theory says this can occur because of gravity, a force attracting those objects to one another or to a single, third object.
Particles that start off on parallel paths sometimes end up colliding. That changed in the early 1900s.īut the fact is, they do meet. That's why if you were to drop a pebble, a book and a couch off a roof, they'd hit the ground at the same time.įor hundreds of years, Newton's theory of gravity pretty much stood alone in the scientific community. Acceleration due to gravity on Earth, is 9.8 m/s² - it never changes, regardless of an object's mass. Where m is an object's mass, and g is the acceleration due to gravity. When you step on a scale, the scale reads how much gravity is acting on your body. The force of gravity acting on an object is also that object's weight. That's why you're not floating around in space right now. When you deal with massive bodies like the Earth, however, which has a mass of 6E+24 kilograms (see How much does planet Earth weigh?), it adds up to a rather powerful gravitational force. So 6.67 x 10E-8 dyne is a miniscule force. A dyne is equal to about 0.001 gram weight, meaning that if you have a dyne of force available, it can lift 0.001 grams in Earth's gravitational field.
So if you put two 1-gram objects 1 centimeter apart from one another, they will attract each other with the force of 6.67 x 10E-8 dyne.
G has the value of 6.67 x 10E-8 dyne * cm 2/gm 2. Where G is the gravitational constant, m1 and m2 are the masses of the two objects for which you are calculating the force, and d is the distance between the centers of gravity of the two masses. Gravitational force = (G * m1 * m2) / (d 2 ) The standard formula for the law of gravitation goes : Gravitational force = (G * m1 * m2) / (d2) So the farther apart the particles are, and/or the less massive the particles, the less the gravitational force.
