All in all, your body inside a Gravitron is pinned to the wall by forces that feel as strong as 3 g, or three times the normal force of gravity, according to NASA. That force is similar to what ...

At this point, your body feels “lighter” because the force of gravity and the normal force, of your seat, are working in opposite directions. The center of the ride is below you, so the ...

Some examples are friction, gravity and the normal force (the force between two surfaces pushing on each other). With real forces, we can say the total force on some object is equal to the time ...

Gravity might not be a more fundamental than the force of a stretched elastic band. Maybe gravity is just an entropic byproduct—an emergent effect of the universe’s tendency to disorder.

For those still holding out hope that antimatter levitates rather than falls in a gravitational field, like normal matter, the results of a new experiment are a dose of cold reality. Physicists ...
