Weight is a force exerted by Earth on a given mass. How do actual weight and apparent weight differ? An object’s apparent weight is the magnitude of the support force exerted on it. An object with no apparent weight experiences weightlessness.
Additionally, how are the weight and the mass of an object related?
Weight of an object is always directly proportional to the mass of the object. i.e. weight of an object will increase or decrease if the mass of the object increases or decreases. Let be the mass of an object and be the weight of the object. While gravitational acceleration.
In respect to this, under what condition is weight equal to apparent weight?
Under what conditions is an object weightless quizlet?
weightlessness occurs in the free fall when the weight of an object seems to be zero. when actions and reaction forces are exerted by two objects, the acceleration of the objects depend on the masses of the objects.
What apparent weight means?
Definition of apparent weight
: the weight of a body as affected by the buoyancy of a fluid (such as air) in which it is immersed, being the true weight minus the weight of the displaced fluid — compare archimedes’ principle.
What does Archimedes Principle explain?
What is Archimedes’ principle? A body at rest in a fluid is acted upon by a force pushing upward called the buoyant force, which is equal to the weight of the fluid that the body displaces. If the body is completely submerged, the volume of fluid displaced is equal to the volume of the body.
What is the apparent weight of a floating body How does it change when we change the liquid body floats in both the liquids?
Explanation: according to the principle of floatation, when a body floats in a liquid, the weight of the body is balanced by the upthrust acting on it which is equal to the weight of the liquid displaced by its submerged part.
What is the relation between actual and apparent weight of a floating body?
Solution : According to law of floatation, weight of a floating body is equal to the weight of the liquid displaced by it.
Why is the apparent weight smaller than the actual weight?
Objects also experience some buoyancy in air, so even in air the normal force (apparent weight) is slightly less than the true force of gravity. Most objects are much denser than air and so the difference is usually small.
