What is the apparant weight if a body in free fall?
in free fall, weight is zero.
The apparent weight of a body in free fall is zero. When an object is in free fall, it means that it is falling under the force of gravity with no other forces acting upon it. In this case, the only force acting on the object is the force of gravity, which causes it to accelerate towards the ground. As a result, the object experiences weightlessness or a sensation of zero apparent weight.
To understand why the apparent weight is zero in free fall, you need to know the concept of weight. Weight is the force exerted on an object due to gravity, and it is equal to the product of mass and acceleration due to gravity (which is approximately 9.8 m/s^2 on Earth's surface).
However, when an object is in free fall, it is experiencing a gravitational force that is balanced by the inertial force caused by its acceleration. This balance of forces creates a situation where the apparent weight is zero. Essentially, the object and the force of gravity are canceling each other out, resulting in weightlessness.
So, in summary, when a body is in free fall, its apparent weight is zero due to the balance between the gravitational force and the inertial force caused by its acceleration.
