A few further comments should be added about the single force that is a source of much confusion to many students of physics - the force of gravity. As mentioned above, the force of gravity acting upon an object is sometimes referred to as the weight of the object. Many students of physics confuse weight with mass. The mass of an object refers to the amount of matter that is contained by the object; the weight of an object is the force of gravity acting upon that object. Mass is related to how much stuff is there and weight is related to the pull of the Earth (or any other planet) upon that stuff. The mass of an object (measured in kg) will be the same no matter where in the universe that object is located. Mass is never altered by location, the pull of gravity, speed or even the existence of other forces. For example, a 2-kg object will have a mass of 2 kg whether it is located on Earth, the moon, or Jupiter; its mass will be 2 kg whether it is moving or not (at least for purposes of our study); and its mass will be 2 kg whether it is being pushed upon or not.
A confluence of heroes! Having accepted defeat at the hands of their evil selves, our heroes await a grim death sentence in the dungeons of Jarmlek. Meanwhile, the Grommulon version of Sarrklon discovers a way to bend the dimensions to his will using the merged Dragonstars and formulates a plan to save the Dragonstar Force. But, it will take merging with himself from the prime dimension. Can his fractured psyche survive such a quantum entanglement, and will he manage to save our intrepid heroes? Imposters in their midst! The mystery of Sarrklon's reappearance may not be resolved, but our heroes have a new problem to deal with: their companions may not be who they say they are. After visiting a resort planet, Jarmon begins acting strangely, even for a changeling! They discover that Jarmon is in fact an imposter in disguise, sowing the seeds of doubt among the entire Dragonstar Force. Who is who, and can anyone be trusted again? Sandstorm – A freak explosion in the British Museum in London ignites a perilous race for an earth-shaking power source buried deep beneath the sands of history. When an ancient artifact points the way toward the legendary ‘Atlantis of the Sands,’ Painter Crowe, an agent for Sigma Force, must travel across the world in search of the lost city–and a destructive power beyond imagining.
The death of Zeffrex! Having sacrificed himself to merge with the Ultra Dragonstar and defeat the Specter of Sarrklon once and for all, the mighty Zeffrex Laserbrand is no more. While mourning the loss of her husband, Princess Laglorial happens upon a fabled wishstone. However, the chaotic power of the wishstone makes things much worse before they are better. And in the end, can Laglorial make the right choice between reviving her dead lover, or saving the universe once again? They stood no real chance, not against the Ruhar. But just when all seemed lost, the Kristang swooped in to save the day. The second alien race to grace the earth with its presence, the Kristang ships sent the Ruhar running.
The force of gravity is the force with which the earth, moon, or other massively large object attracts another object towards itself. By definition, this is the weight of the object. All objects upon earth experience a force of gravity that is directed "downward" towards the center of the earth. The force of gravity on earth is always equal to the weight of the object as found by the equation: Fgrav = m * g where g = 9.8 N/kg (on Earth)The air resistance is a special type of frictional force that acts upon objects as they travel through the air. The force of air resistance is often observed to oppose the motion of an object. This force will frequently be neglected due to its negligible magnitude (and due to the fact that it is mathematically difficult to predict its value). It is most noticeable for objects that travel at high speeds (e.g., a skydiver or a downhill skier) or for objects with large surface areas. Air resistance will be discussed in more detail in Lesson 3. Return to Top With so many books on physics out there, it can be challenging to find a good place to start. These books on physics about force and more cover the science behind force and gravity as well as other topics in physics, such as electricity, space-time, relativity, and quantum physics. Desperate times, desperate measures! When Sarklonn reveals his plan to destroy all the dragons in the galaxy with the Dragonstar, Jeffrex Laserbrand and the rest of the Dragonstar Force must form an uneasy alliance with their former Dragon foes, the dragonspawn of Fraxitarr! The dragons arm Jeffrex with a new weapon of their own creation, the laser-axe, Glorybringer, in hopes he can use it to bring Sarrklon's reign to an end. Considering the frequent nature of his publishing schedule, specifically the fact that he releases so many full-length novels in a year, it should come as no surprise to learn that Alanson is self-published.
Dragons within! Shussalina, the forgotten daughter of Sarrklon, has assembled the fractured Dragonstar and seeks her revenge! Using the magic of Dragonstar, she covertly travels to the peaceful world of Ploximar, bringing with her a seemingly magical pox, infecting the local populace. What seemed to be a disease turns out to be millions of microdragons, shrunken down to microscopic scale by the power of the reformed Dragonstar. Unbeknownst to her, Tanskler and his new friends Glorp, the gelatinous golem, and Minnialissa, the fae witchling, are on a diplomatic mission to Ploximar when Tanskler falls ill to the dragon pox. His companions shrink down and enter his body to take on the microscopic threat. Physics of the Impossible explores the science of several “impossible” things, such as time travel and starships. The book touches on nearly every corner of physics, including force, gravity, and the physics of how objects interact with each other. Physics of the Impossible is a great way to dive into physics by learning about it through the context of science fiction.The universe is in chaos! The evil Sarrklon, an alien being born of pure hatred, has amassed his secret armies to rain destruction upon the people of the Allied Worlds. A young man, Zeffrex Laserbrand, is thrust into the conflict when he discovers he is the descendent of a great hero, and one of the only ones capable of wielding the Dragonstar, a magical weapon capable of defeating Sarrklon and bringing peace to the galaxy. But first, it must be found. Joe had made peace with his fate. But now the UN has decided to send a few dozen elite troops with him, a development that has only saddled him with more responsibility. A universe at peace! All seems well for the Dragonstar Force. Jeffrex Laserbrand, having successfully restored the natural balance of the universe, has settled in with Princess Laglorial on her homeworld of Zlaxx. When vacationing offworld with their newborn son, a massive explosion rends their homeworld apart. The Dragonstar Force reconvenes to avenge the planet's sudden destruction, but what they find, haunts them. The latent power of the Ultra Dragonstar manifests as a Phantom Dragon, merged with the life force of Sarrklon, and it seeks revenge on the Dragonstar Force. Can they defeat an enemy they can't see? There are hundreds of books on physics about force, gravity, and the way the objects of the universe interact. If you’re looking for a good one to read, whether you’re a beginner or a seasoned physics student, these six books are a great place to start. Many people get interested in physics through science fiction. If this is why you’re looking for a great book on physics about force, look no further than Physics of the Impossible by Michio Kaku! This is a great read, no matter your experience level with physics. Michio Kaku does a great job of exploring even advanced physics topics without becoming too complex or abstract.
Written by author James Rollins, The Sigma Force series is obviously about The SIGMA Force. It is a fictional division of the U.S. DARPA program whose purpose is to investigate and secure sensitive information that could be a threat to the United States. Before the publication of ‘Expeditionary Force’, most people had no idea that Craig Alanson existed. ‘Expeditionary Force’ put him on the publishing map. People were drawn in by his story of a United States soldier who takes to the stars to fight an alien force that might or might not wish him harm. Even if you want to move on to more advanced, in-depth books on physics about force specifically, The Physics Book is a great handbook to have around. It will give you a clear understanding of physics in general without over-complicating any topics or bringing in the complex mathematics of physics. He got a promotion out of the whole deal but now something grim awaits his future. Joe agreed to take a captured alien starship out into space for a foolish mission he knew he would never survive. Earth was invaded by two warring races. The human race was drawn into a conflict that they knew nothing about. Colonel Joe Bishop was one of those that survived the resulting melee.Mind over matter! Having escaped from the Grommulon dimension with the intact Dragonstar, the Dragonstar Force now finds themselves trapped in prisons of their own minds. It turns out that merging with evil alternate-dimension versions of themselves has caused more problems than it may have solved. Now, our heroes fight for their very souls and must battle their own personal demons if they wish to survive! Alanson made quite the splash when he appeared on the publishing scene in 2016. A lot of people think that ‘Columbus Day’ was the author’s first published novel and for good reason.
Great Deal
