A variety of robot-assisted surgical systems have been proposed to improve the precision of eye surgery1,2. However, to date, little attention has been paid to patient head motion, which is frequent among patients undergoing eye surgery under monitored anesthesia3, also known as conscious sedation...
If we take a unit area at height h, then the vertical force from below, on this unit area, is the pressure P. The vertical force per unit area pushing down at a height h+dh would be the same, in the absence of gravity, but here it is not, because the force from below must ...
Related to Gravity constant:Acceleration due to gravity gravitational constant n.Abbr.G The constant relating the force of gravitational attraction between two bodies to the product of their masses and the inverse square of the distance between them in Newton's law of gravitation. It equals 6.67 ...

Gravity and acceleration are the same according to Einstein's Equivalence Principle. Density also has the same effect as gravity because gravity attracts matter thereby increasing matter density. The laws of Physics and all the constants of nature such as the Speed of light, Planck's constant, ...
In a physics experiment to measure the acceleration due to gravity, if the measured value is consistently lower than the actual value, which of the following might be the main source of error? A. The length of the pendulum was measured inaccurately longer than it actually is B. The time ...
