MACHOs include brown dwarfs, weak stars that exert a gravitational pull but emit no light. WIMPs, on the other hand, would constitute a radically different form of matter left over from the big bang. Research into the exact nature of dark matter and dark energy continues. In what appears ...
Roughly nine billion years after the Big Bang, the universe’s expansion began to speed up again—defying the gravitational pull that should have been slowing it down. Scientists realized that some unknown force was pushing space apart at an accelerating rate. They named this mysterious phenomenond...
The tonic and dominant chords act as harmonic poles with their own gravitational pull. That neatly fits the diatonic chords into three categories—tonic, pre-dominant and dominant. It also generally describes forward harmonic motion in a chord progression—from tonic to pre-dominant to dominant and...
What factors determine the gravitational potential energy of an object? Is gravitational force an example for potential energy? What is the link for gravitational field strength, gravitational potential energy, height, and mass? An apple with a mass of 154g is placed 1.5m above the...
What factors determine the gravitational potential energy of an object? What is the horizontal component of gravitational acceleration? What affects the magnitude of gravitational force? How much does the force of gravity depend on the distance between two objects?
Amplitude refers to the angle of swing, or how far back the pendulum swings. A resting pendulum has an angle of 0 degrees; pull it back halfway between resting and parallel to the ground and you have a 45-degree angle. Start a pendulum and you determine the amplitude. Experiment with di...
knowledge, high action, and high ethics, all of which are rooted in critical thinking and a robust cultural foundation. Mediocrity, akin to gravity, exerts a force that automatically and naturally pulls one down. Parrish's book is dedicated to liberating oneself from the gravitational pull of ...
Then came the name brands:Kenmoreappliances,Lands’ Endclothing, and the unbeatableKenmore Directline. Sears wasn’t just selling items; they were creating the brands people swore by. Each brand had its gravitational pull, drawing consumers into the orbit of Sears stores and catalogs. It was syn...
The values based on gravitational wave observations are currently consistent with both values, due to significant error bars in this extremely sensitive method; but other more mature methods are now of sufficient accuracy that they are basically only consistent with one of the two values. Currently ...
It is impossible for a moon to exceed the mass of its planet because the definition of a moon is an object of smaller mass orbiting a planet. The more mass an object has, the more gravitational pull it exerts on its surroundings, so if the Moon was more massive than Earth, we would ...
