From the word itself, we can say it is not the actual weight.Now we need to know, where do we use this word and what this actually mean?In the case of weightlessness one person feels it has lost his / her weight. Here person falls in full influence of gravity alone. This weight is not the actual weight. This weight is called apparent weight which is actually impossible but one can experience in elevator or some thimg like that
Plz define APPARENT WEIGHT. i need simple and best definition. thanx?
Definition: "A Parent Weight": The reading reported by a weighing scales after you have laboriously managed to persuade your Mammy or your Daddy to stand on them. Definition: Apparent Wait: The (usually grossly exaggerated) time that seems to pass while life passes you by in a traffic jam, queue for the till, standing at a bus stop, etc. ---- Definition: Apparent Weight: The reading from a scales on which the object of interest and other disposable paraphernalia were present, less the previously determined weight of that paraphernalia. [e.g. You weighing yourself while wearing your pyjamas+slippers, with these known to weigh 500g by themselves! So AW(nude self) = W(self plus night attire) - 500g (Weight of night attire).
Define mass,applied force,gravitational force and weight indicating?
Mass: Definition- amount of matter Unit of Measurement: grams (g) or kilograms (kg) Note: does not change from place to place Applied force: Definition- force applied on a certain object Unit of Measurement: newtons (N) Gravitational Force: Definition- force of gravity; force due to gravity Unit of Measurement: newtons (N) Note: changes from place to place Gravitational force is an applied force on an object. The gravitational force causes the object to have a weight. The higher the mass of the object or the higher the gravitional force in that area, the higher the weight will be. (The unit of measurement for all forces are newtons) Hope I helped! :)

real weight = true weightTrue weight is simply weight. What is your true weight? It's simply [math]mg[/math]. Mass multiplied by gravity. End of story.Now, Apparent weight. I'll denote it by [math]WA[/math]. It's defined as[math]WA=N[/math]where [math]N[/math] is the normal force in the direction opposite to the direction of gravity. That is away from the center of the earth. You may be standing and someone may be trying to push you horizontally. That normal reaction force doesn't count. Only the vertical Normal Force counts.So suppose you jump from the top of the building because your dog died. You are falling. Your '(True) Weight' is simply [math]mg[/math]. Your Apparent weight is [math]0[/math]. Because there is no normal force applied on you currently. (Off course the ground will apply one hell of a normal force when you finally reach it.)Now suppose you are standing in an elevator at rest. True weight, off course is [math]mg[/math]. But Apparent weight is also [math]mg[/math]. Because you are at rest, [math]N=mg[/math].Elevator moving with constant speed: [math]N=mg[/math]Suppose the magnitude of elevator's acceleration is[math]|a|[/math].Elevator moving upwards, and slowing down: [math]N=mg−m|a|[/math]Elevator moving upwards, and increasing speed: [math]N=mg+m|a|[/math]Elevator moving downwards, and slowing down: [math]N=mg+m|a|[/math]Elevator moving downwards, and increasing speed: [math]N=mg−m|a|[/math]So, why did they introduce the concept of Apparent Weight. Apparent weight is the weight you 'feel'. Think about it! When you are falling, you feel weightlessness. Hence Apparent Weight is [math]0[/math]. When in an elevator with moving upwards with increasing speed, you feel heavier. Hence more is the Apparent Weight!
Apparent forces arise in non-inertial frames of reference, frames of reference that are themselves accelerating. When this happens, the motion of bodies in this non-inertial frame don’t seem to obey Newton’s laws.For a person standing still next to a stop sign, no apparent forces are needed to explain the motion of the stop sign. Only gravity acts which is countered by the reaction from the ground, and the net force being zero, the stop sign at rest remains at rest.If you are sitting in a car that is accelerating, and you apply Newton’s law to a stop sign on the sidewalk, then from the point-of-view of you in the car, the stop sign is accelerating even though no net force is acting on it. An apparent force can be created to fix this discrepancy between the laws of physics applied in the two frames. If one sticks to inertial frames, one doesn’t need an apparent force to explain motion in any of those frames.
Can you explain express, implied, and apparent authority?
An agent who acts within the scope of authority conferred by his or her principal binds the principal in the obligations she creates against third parties. There are essentially two kinds of authority recognized in the law: actual authority (whether express or implied) and apparent authority. Express actual authority means an agent has actually been expressly told she may act on behalf of a principal. An insurer specifically authorizes an agent to bind certain risks. Implied actual authority is authority an agent has by virtue of being reasonably necessary to carry out his or her express authority. As such, it can be inferred by virtue of a position held by an agent. An insurance agents implied authority would suggest an agent can accept premium payments on behalf of the principal (i.e. the insurer). Apparent authority (also called "ostensible authority") exists where the principal's words or conduct would lead a reasonable person in the third party's position to believe that the agent was authorized to act, even if the principal and the purported agent had never discussed such a relationship. An example would be an agent that displayed signs, preprinted company forms and stationary with the company logo would lead one to believe that the agent had the authority to act for the principal (the insurer).
The apparent weight of the body decreases only when the lift is accelerating or else their is no change.The reason for feeling weight:When we exert a force on the floor of the lift i.e. our weight, according to Newton's third law the floor of the lift exerts an equal and opposite force on us. This reaction force is felt as the apparent weight and is called normal reaction force.You need to be familiar with the term 'Pseudo Force'.Pseudo Force: Any force that is postulated to account for apparent deviations from Newton's laws of motion appearing in an accelerated reference system.Pseudo force always acts opposite to the direction of acceleration.Let's say the lift is moving downwards with an acceleration 'a'.let's consider the forces acting on the floor of the lift.A force due to weight of our body acts downwards=mg.Pseudo force acts upwards=ma (since the lift is accelerating downwards)Net force=mg-maTherefore, their is a net decrease in downward force and hence a net decrease in normal reaction force. So, the apparent weight of the body decreases.Note: The above problem has been solved with reference to the frame of the lift, which is a non-inertial frame.
What is the definition of an unbalanced force?
An unbalance force is one that is not opposed by an equal and opposite force operating directly against the force intended to cause a change in the object's state of motion or rest. Take this: Object, O is at rest and subjected to a force from the left as shown: Let ====> represent the force to change the object's state of motion or rest on object. O This unopposed (unbalanced) force will cause the object to move to the right. ====> O Let O <==== represent an opposing force of equal magnitude operating on object O. When the forces are opposed and impinging on the object ====> O <====, the object will not move because each force is balanced by an equal and opposite force. However, if the forces are unbalanced and aligned thus, ====> O <========, the larger force coming from the right is unbalance by the one from the left. So, the object will move toward the left. The picture is more complicated than I can illustrate here because an opposing force my be impinging on the object from an angle. Overall, it is the "net" unbalanced force that will cause the object to move or change its state of motion. LOL i hope that makes sense...Good luck in your studies!!
