is weight and support the same force?
96297
Weight is the force acting downwards and support is the force which is acting upwards (A.K.A Normal Force). In most cases if the support does not undergo buckling or breaking when weight is applied, their magniture will be the same.\nMag of Weight = Mag of Normal force.\n\nBut the difference is they act on different objects. i.e. weight acts on the supporting plane and the normal force acts on the object that is put on the support.\n\n-->  p  <--\n\nDanEelectrician@yahoo.com

25 lbs\nThe distinction between mass and weight becomes obvious when we move away from the earth's surface. For example, on the surface of the Moon gravity is only about one sixth as strong as on the surface of the earth. A one kilogram mass is still a one kilogram mass – mass is an intrinsic property of the object. However, the weight of the object – the downwards force due to gravity – is only one sixth of what it is at the surface of the earth; that is, only one sixth of what we would expect one kilogram to weigh.

this is the amount of force.  Force equals mass times acceleration.  The mass is ur bodyweight in kilos and the acceleration is gravity 9.8m/s/s

Mass is a constant; weight varies by gravitational pull.

weight = mass * gravity\ntherefor\nmass = weight/gravity\n\nsorry naughty but you're wrong, if you go to the moon or jupiter you will have the same mass you have in earth but you'll have a different weight

Weight is the amount of force on an object and mass is the amount of matter in that object

Mass is a fundamental quality. No matter where something is, it has the same mass. Weight, on the other hand, is the force that gravity exerts on the mass. Though in standard units we measure both in pounds, technically mass is measured in pounds mass, while weight is measured in pounds force. In SI units, mass is measured in grams, and weight in newtons.\n\nTo answer your question, weight will change with distance from the earth's center. Mass will not.

Mass is a direct measure of an object's inertia, and the strength of its gravitational pull. More often, we find it easier to say that mass is a measure of quantity. More mass = more interia, so it works out.\n\nWeight, the way we think of it, is a measure of the net downward force an object undergoes when placed in a gravitational field ("down" meaning toward the source of the gravitational force in question). On Earth, weight is a measure of the effect gravity has on an object.\n\nSince more mass = more for gravity to pull, objects with more mass also have more weight (at the same location in the same gravity field), so we generally use weight and mass interchangeably, and this doesn't cause too many problems.

yes \n\nbasic fdormula = mgh\n\nhere mg= weight of body[mass * acc. due to gravity}\nso it can be\nweight* height\n\nalso weight is a kind of force\nso weight = Force represented by F\nand 'd' = distance\nso it can be F*D where f= force[weight] and d=[distance]

There are many systems of measurement for force, ft/lbs, newtons etc. you can define your own if you wish. what is it you are really asking?

When the pendulum reaches the 90 degree point in the motion, the force of gravity and the applied force are equal for an infintesimal moment. \n\nThat means there is no "weight" to support. Weight is a function of mass and the force of gravity. Since gravity = 0 relative to the object, then weight = 0

You mean Newton's 2nd law of motion, don’t you?\n\nForce = mass * acceleration\n\nI like this law, a lot, actually.\nIt may not seem very intuitive at first to someone trying to learn it, but with practice, you'll come to understand.\n\nThe basic concept is that a [net] force applied to an object causes it to accelerate.  When you push on something, it moves.  They key work being a "net" force.  If there is no net force (i.e. F = 0), there is no acceleration.\nThe force the chair is exerting on you, called the "Normal" force is necessary because while you are sitting in the chair are you falling towards the ground?  No, of course not.\n\nWe all know that Earth (gravity) exerts a force on you in the downward direction, called "Weight".  Without a balancing force, you would continue to accelerate downward.  If the chair did not exert a normal force back upward to cancel weight, there would be a net force acting upon you in the downward direction which would cause you to accelerate downward.\n\nA similar case is true for other objects, like when you push on a wall.  In this case, it is not gravity which exerts the force, you are doing it.  In order to keep the wall from accelerating when you push on it, the wall must exert a force back which is "normal" to its surface.  Eventually, however, the wall will not be able to provide ample normal force to counter your push and parts of the wall will begin to accelerate as the wall breaks.

Yes the scale will reflect the additional weight.\n\nThe downward force on the water is still an additional downward force which is measured by the scale.

Weight is define by your mass times the acceleration due to gravity where you are.  So you mass is the same anywhere in the universe but your weight will be effected by where you are.  Now what is weight measured in?  This is dependent on the units you use for mass and acceleration.  Using kilograms for mass and m/s^2 for acceleration you will get newtons.  Use slugs and ft/s^2 you get a pound-force.  Using a standard equivalence between pounds and kilograms you get kilogram-force.  Many people think kilograms is a measure of weight when it really is not, its kilograms-force.  There should be somewhere on most scales that will show a lbf or kgf instead of just lb or kg.  Newtons is the standard SI unit of measure though.\n\nEdit: when i say acceleration, i mean acceleration due to gravity.  Weight *is* a unit of force.\n\nhoarp001:  Weight is a unit of force, all the units you put there are units of mass, not weight.\n\nzeno : "From other experiments, we know that g, or acceleration by free fall is actually an acceleration of 9.8N at sea level"  G is acceleration due to gravity.  According to your "9.8N" your mass would be a kg*N, not newtons.  Pay attention to your units, especially since he was asking a unit question.  Standard SI would be 9.8 meters / second^2, CGS would be 980 centimeters / second^2.  If using standard engineering units, it would be 32 feet / second^2.  Bascially anything that is a length per time ^2.

No, the same molecules and atoms are on (in) the screens regardless of what the image is.  Their appearance changes, but there is no change in weight.

Ok, let's set this straight. Weight is a measure of the force exerted on an object by a gravitational field. It is measured in NEWTONS. Most people are getting this mixed up with mass, which can be measured in metric tons and doesn't change from one gravitational field to another. The weight of the lead on the moon is only 166 Newtons.

The musculoskeletal system is basically a bunch of levers and fulcrums, with forces being applied at the points of muscle insertion.  Since the points of insertion are fixed and the location of the weight is fixed in this example, if you double the force being applied by the weight, you must also double the force being applied by the muscle to hold the weight in a static position.  However, force and energy expenditure are not really the same thing, and I don't know if they have a linear relationship to eachother.  I would guess that muscular efficiency i.e. calories burned per unit of force applied, varies based on the amount of force applied.
