2015年8月15日 · In summary, Veritasium made a video explaining that a flight wheel can feel weightless when spinning due to the combined angular velocity of the wheel's rotation around its stick and the stick's rotation around the hand. This creates a torque that counters the torque from gravity, making the wheel feel lighter.

2020年8月15日 · "Anti-Gravity Wheel Explained" by Veritasium It is the second video in particular that bothers me. It seems as if he can lift the wheel up over his head while it's spinning and precessing with ease, but when it's not spinning nor precessing, then he …

2015年5月19日 · This is the Anti gravity wheel video from Veritassium. I have a similar problem to calculate the forces on arm. How can I calculate the precession force pushing the arm vertically ? Lets assume that the angles between shaft and arm …

2016年1月11日 · Many of you might have seen veritasium's video on the "Anti-gravity wheel". Through one of the comments, I was introduced to the idea that the reason the apparatus is so easy to lift is because the energy to do so comes from the spin of the wheel, i.e. its rotation slows down as it is lifted and speeds up again as it's lowered.

2015年5月19日 · This is the Anti gravity wheel video from Veritassium. I have a similar problem to calculate the forces on arm. How can I calculate the precession force pushing the arm vertically ? Lets assume that the angles between shaft and arm is 90° the angles between shaft and wheel is 90° The wheel...

2014年3月12日 · For example, a ball that falls onto a scooped wheel to drive it. Take the ball and move a sheet of anti-grav material under it. As the ball now no longer feels the earth's gravity, we can push it up above the wheel without using any energy. Now remove the anti-grav sheet. The ball will fall onto the wheel and thus generate energy.

2006年7月22日 · Actually anti-gravity is observed in nature. It is now apparent that the universe is expanding at an accelerated rate. This can be accomplished by introducing a non-zero cosmological constant into Einstein's equations of gravity. This non-zero cosmological constant acts in nature as anti-gravity.

2016年10月1日 · In summary, spinning a wheel does not generate lift or change the mass or total downwards force of the wheel. However, in the presence of air, the wheel can be designed to intentionally generate lift, similar to a helicopter rotor, without affecting the force of gravity or the mass of the wheel.

2017年4月3日 · The wheel has three forces on it: the force at the right hand, the force at the left hand, and the force of gravity. There is no torque at the right hand because r=0. There is a torque in the y direction due to gravity.

2013年6月25日 · FAQ: Magnetic levitation of vehicles vs anti-gravity What is the difference between magnetic levitation and anti-gravity? Magnetic levitation (Maglev) uses the repulsive force between two magnets to lift and propel a vehicle, while anti-gravity is a theoretical concept that suggests the existence of a force that counteracts the effects of gravity.
