In most other contexts when you talk about a physical object you call it a "mass". we used scales to determine that W mg (weight mass x acceleration of gravity). Therefore the force of gravity on earth is 9.81 x mass. Thats wrong and it may mean gravity travels at different speeds across. There is about a 0.7% change in force of gravity from North Pole to the Nevado Huescaràn mountain in Peru (you are heavier at the North Pole) - or about 0.01% for every degree of latitude (on average). The surprise answer that reshapes reality We long assumed particles carrying the force of gravity couldnt have mass.
Large bodies such as the Sun, the Moon and the Earth all have very large masses. Weight includes only the force due to the local gravitational field, not the forces due to buoyancy, air currents, magnetic fields, bungee cords, or anything else. Weight - a force downwards due to gravity. This is one reason why even cheap 5-digit digital balances (you can get them at Amazon for about $30) ship with calibration weights - to get that 0.01% accuracy you need a local reference calibration. The weight will not in general equal the total downward force. Thus it is OK to calibrate a scale in grams and indicate mass in grams - as long as you understand that you had to calibrate locally using a known mass to get the conversion factor. When you know the ratio of weights you know the ratio of masses. So when you want to determine the mass of an unknown object you can use scales to compare its weight with that of a known object. In physics, gravity (from Latin gravitas weight 1) is a fundamental interaction which causes mutual attraction between all things with mass or energy. 11 results for 'to drop under the force of gravity'. Explore more crossword clues and answers by clicking on the results or quizzes. This is because weight is a function of position on earth - mass is not. For the word puzzle clue of to drop under the force of gravity, the Sporcle Puzzle Library found the following results. But a calibrated weight is never calibrated in Newtons - it is calibrated in grams. The (calibrated) object you place on a scale is called a "weight" - because that is the property you most care about. In our lab, we used a spring scale to measure the force of gravitational attraction between the Earth and the 8 different-sized balls.
So when you do calculations about the force in the cables due to acceleration of an elevator car you need to know both it's mass and it's weight. When you are considering the force of gravity you use "weight". If you care about the inertia you use "mass".
