How can weight be measured physics
Web30 de abr. de 2015 · Weight is the force on an object exterted by a gravitational field, and is proportional to the mass. On the Earth's surface W = m*g. We can convert weight to mass if our measuring scale is calibrated, usually with an object of known mass. This would work for any planet. Even though the weight would change from planet to planet, the mass would … WebWeight is the measure of the force of gravity acting on a body.The formula for weight is given by: w = mg What is the relationship between mass and weight? Technically, weight is the mass of a body multiplied by the …

Webwork, in physics, measure of energy transfer that occurs when an object is moved over a distance by an external force at least part of which is applied in the direction of the displacement. If the force is constant, work may be computed by multiplying the length of the path by the component of the force acting along the path. To express this concept … WebOne way to measure the mass, say, of a proton, is to put it in a mass spectrometer. Accelerating it in a known electric field gives it an amount of kinetic energy proportional to its charge. Causing the proton to move in a circular path in a uniform, well-calibrated magnetic field allows the momentum to be measured quite precisely.
Web1. power is all about converting whatever your work into the work with 1 second of window. 2. in most cases, you do work for more than 1 sec. thus you have to do divide them by the time it take to do the work. e.g. work_of_pushing_a_box_right = 30J, time = 3s. power = work/time = 30J/3s = 10J/1s = 10W.
