Einstein’s general relativity explains gravity as the result of spacetime curvature due to mass, contrasting with magnetism’s dual ability to attract and repel. This theory introduces the concept of gravity wells, central to understanding gravitational pull. Credit: SciTechDaily.com Why does gravity...
Is normal force the y-component of the force of gravity? Does static friction move objects? Is centripetal force an outwards force? Is friction an applied force? Does Newton's third law apply to an object in motion? Is centripetal force contact or noncontact? Does the strong force bend? Is...
You watch what they do, listen to what they say and to the other sounds they make, and see how they respond to their environment -- what things attract them and what things repel them, what they eat, and so forth. You can also cut open other creatures and look -19- at their ...
Objects with like charges repel each other, while objects with opposite charges attract each other. The magnitude of the repulsive or attractive force in relation to the charge of the objects and their distance is described by Coulomb's law....
Someone asked, if the temperature had such an effect on gravity, the rocket would have been so hot that it would have been impossible to control it. Right? When two objects attract each other, each changes the density of the Yizi gas around it, and creates a gravitational field, the corr...
Does a gravity theorist know more about your business than you do? At PayPal, I once interviewed a physics PhD for an engineering job. Halfway through my first question, he shouted, "Stop! I already know what you're going to ask!" But he was wrong. It was the easiest no-hire decisi...
Hence, they attract positively charged objects. Water shows neutral electric charges as it encompasses an equal number of protons and electrons. But when the negatively charged object comes in close contact, the matching ions repel each other and move away from the object, pushing the positively ...
(upper right) if the matter is off to the side, then gravity will be stronger, or weaker, or point in different directions at different points on the surface, but the total stays the same. (bottom) matter ...
