The weight of a body is zero during free fall. Why?
Answers
Answer:The weight of an object in freefall is NOT zero.
In physics, the definition of weight is the force of gravity upon an object. To remove a common misconception, although we generally measure the weight of an object by measuring the force between the object and the source of the gravitational pull (e.g. Earth) using a scale. However, only two things are necessary for an object to have weight:
The object has mass
The object is being accelerated (“pulled”) by one or more other objects with mass which create a net gravitational field.
An object in empty space free of all graviataional fields (of course not possible) would have no weight. It could be moving, and could even experience forces, such as electromagnetic forces, but in the absense of another source of gravity, no weight.
An object in freefall is accelerating in response to a gravitational field. For example, a spaceship in orbit around Mars, or an airplane plumetting towards Earth both have weight. The same spaceship orbitting Earth at the same height would weigh more because of Earth’s larger gravitational acceleration.
Answer:
Explanation: Because during free fall the falling body does not depends upon other support as the body becomes weightlessness so it becomes zero
