Can gravity be manipulated?
Can gravity be manipulated?
The better news is that there is no science that says that gravity control is impossible. First, we do know that gravity and electromagnetism are linked phenomena. Another way is through new theories from quantum mechanics that link gravity and inertia to something called “vacuum fluctuations.”
What is the fastest a human has ever gone?
Is normal contact force equal to weight?
Many forces do come from objects being in contact with each other. The normal force is usually symbolized by N . In many cases the normal force is simply equal to the weight of an object, but that’s only when the normal force is the only thing counteracting the weight.
Is normal force equal to applied force?
An applied force is a force that is applied to an object by a person or another object. If a person is pushing a desk across the room, then there is an applied force acting upon the object. The normal force is the support force exerted upon an object that is in contact with another stable object.
What is the strongest and weakest force?
Actually, gravity is the weakest of the four fundamental forces. Ordered from strongest to weakest, the forces are 1) the strong nuclear force, 2) the electromagnetic force, 3) the weak nuclear force, and 4) gravity.
Do astronauts drink their own urine?
Astronauts have been drinking distilled urine since 2009, and they currently recapture 93 percent of wastewater, but the system they’re using now is heavy, slow and has been prone to breaking down. It spins the urine at high speed to separate out the water vapor, then treats it chemically.
What is the fastest jet in the world?
Lockheed SR-71 Blackbird
Can astronauts poop in their suits?
The Apollo astronauts defecated into fecal collection bags that were part of their flight suit. This system was so prone to failure that the crewmembers were specifically placed on a high-protein diet to reduce the amount of waste they produced.
What was the fastest car ever made?

Has anyone ever floated away in space?
On February 7, 1984, Bruce McCandless became the first human to float free from any earthly anchor when he stepped out of the space shuttle Challenger and flew away from the ship. McCandless, who died on December 21, 2017, had a long and storied history in NASA’s space program.
Is normal force equal to gravity on an incline?
Breakout the gravity force vector into components which are parallel -mg*sin(Θ) and perpendicular -mg*cos(Θ) to the incline. The normal force will be equal and opposite to the perpendicular gravity component so N = +mg*cos(Θ).
How do I calculate normal force?
The weight of an object equals the mass of the object multiplied by the acceleration of gravity. Multiply the two values together. In order to find the normal force, you need to multiply the weight of the object by the cosine of the angle of incline.
What is the most powerful force in the universe?
Who was the 2nd man to walk on the moon?
