With compressive force counted as negative tensile force, the rate of change of the tensile force in the direction of the g-force, per unit mass (the change between parts of the object such that the slice of the object between them has unit mass), is equal to the g-force plus the non-gravitational external forces on the slice, if any (counted ...
The increase in weight is equal to the amount of liquid displaced by the object, which is the same as the volume of the suspended object times the density of the liquid. [1] The concept of Archimedes' principle is that an object immersed in a fluid is buoyed up by a force equal to the weight of the fluid displaced by the object. [2]
Thermal input necessary to evaporate all surface water on Earth. [243] [244] [245] Note that the evaporated water still remains on Earth, merely in vapor form. 4.2×10 27 J Kinetic energy of a regulation baseball thrown at the speed of the Oh-My-God particle, itself a cosmic ray proton with the kinetic energy of a baseball thrown at 60 mph (~50 J).

Dutch Prime Minister Dick Schoof will miss the COP29 climate summit after clashes in Amsterdam this week between Israeli soccer fans and pro-Palestinian protesters as his government investigates ...
Pollard’s family called police at about 1 a.m. Tuesday to say she had not been seen since going out at about 5 p.m. Monday to search for Pepper, her cat.
They did the math. Sheriffs in Wisconsin sprang into action Friday night when a 10-year-old boy called 911 with an epic educational emergency: math homework.
Suppose that, when the rock is lowered into the water, it displaces water of weight 3 newtons. The force it then exerts on the string from which it hangs would be 10 newtons minus the 3 newtons of buoyant force: 10 − 3 = 7 newtons. Buoyancy reduces the apparent weight of objects that have sunk completely to the sea-floor.
