The force can be determined like so: F = ma F = m a, where F F is the force, m m is the mass and a a is the acceleration (the gravity in case of weight). So W = mg W = m g, where W W is the weight, m m is the mass and g g is the gravity. By the way, weight is measured in newtons, while mass is in kilograms. 1N =1kg ⋅m ⋅s−2 1 N = 1 k g ⋅ ...
When being asked for the weight force, it is generally implicitly understood, it's the gravitational force of an object on the earth (or it will be specifically called out on what body and the acceleration due to gravity on that body, e.g. find the weight force of a person of 68 kg mass on the moon which has an acceleration due to gravity of $1 ...
Weight is the measure of how much force does gravitation exert on an object. It can be expressed in units of mass, by dividing by the Earth's standard gravity: $$\text {weight} = \frac {\text {gravitational force}} {9.80665\, m/s^2}$$. Inertia, or inertial mass, is a measure of how much force do you need to apply to an object to cause ...
But weighing machine measures our weight and its unit is in kgf (kilogram force) not kg, its a metric unit of weight, and as we know that N (Newton) is a SI unit of weight and 1Kgf = 9.807N. So as from Newton’s second law F= ma, Weight (W)= mg. if a body have a mass of 1kg and g=9.807 m/s^2.
1. The astronauts on cosmonauts on the International Space Station exhibit a marked difference in their "true" and "apparent" weights. Their true weight, tautologically mass times gravitational acceleration, is about 10% less than what it is on the surface of the Earth. Their apparent weight is essentially zero.
$\begingroup$ @Jake - we called it "weight" long before people made the distinction between mass and weight: according to the etymological dictionary, "The original sense was of motion, which led to that of lifting, then to that of "measure the weight of." The older sense of "lift, carry" survives in the nautical phrase weigh anchor."
A mass of 100 grams has no directional component, whereas a weight of 1 Newton has both directional and mass components. It is the directional force necessary to accelerate 1 kilogram of mass at the rate of 1 meter per second, per second (1Kg * 1m/sec^2). These differences are important to avoid confusion in dimensional analysis.
The scale is calculated by measured weight of known mass in the lab x multiplier used for leverage = weight of person on scale. So if the mass weighs 3 lbs, and there's a 50x multiplier at a specific notch on the scale, then the mass is putting 150 lbs of force on the lever in one direction. If the lever is balanced at that setting, that means ...
What is the difference between center of mass and center of gravity? These terms seem to be used interchangeably. Is there a difference between them for non-moving object on Earth, or moving obje...
71 1 2. Add a comment. Sorted by: In linear (translational) cases, the inertia is called mass m m. The unit is [kg] [k g] The larger the mass, the tougher it is to push something to move or to slow something down. In rotational cases, the inertia is called moment of inertia I = ∑ mr2 I = ∑ m r 2. The unit is [kg ⋅ m2] [k g ⋅ m 2]
