## What is the acceleration of a weightless object?

At every point on the trajectory, the acceleration is equal to g downward since there is no support. A considerable amount of experimentation has been done with such ballistic trajectories to practice for orbital missions where you experience weightlessness all the time.

## What is meant by weightlessness in physics?

weightlessness, condition experienced while in free-fall, in which the effect of gravity is canceled by the inertial (e.g., centrifugal) force resulting from orbital flight. The term zero gravity is often used to describe such a condition.

What is weightlessness in physics class 9?

Weightlessness is a condition when your body is in free fall and the acceleration is downward at gravity. This condition can be defined by the term zero gravity. So weightlessness occurs when there is zero support of force on our body.

### What is weightlessness example?

It can be accurately described as the condition in which the body does not feel its weight at all. Example- When an apple falls from a tree, it won’t feel its weight. This condition which is experienced by anybody during a free fall is called weightlessness.

### What is apparent acceleration?

General Relativity: apparent acceleration of gravity. 2.1 Gravitation as an apparent force. The starting point of Einstein’s Theory of General Relativity was Galileo’s (1564– 1642) well-known observation that falling bodies of different masses accelerate equally under gravity (ignoring the friction of air).

What is the acceleration of an object traveling at a constant velocity?

Explanation: If an object is moving with a constant velocity, then by definition it has zero acceleration.

#### What is weightlessness in Class 11?

Class 11 Physics Gravitation. Weightlessness. Weightlessness. Weightlessness is a condition of free fall, in which the effect of gravity is cancelled by the inertial (e.g., centrifugal) force resulting from orbital flight. There is no force of gravity acting on the objects.

#### What is weightlessness in physics?

Ans: Weightlessness is a condition experienced while in free fall, in which the effect of gravity is cancelled by the inertial (for example, centrifugal force) force resulting from the orbital flight. Therefore, weightlessness in physics is the absence of the sensation of weight. 2. Is Weightlessness Implied in the Absence of Gravity?

How does weightlessness occur in an aircraft?

The “weightlessness” you may feel in an aircraft occurs any time the aircraft is accelerating downward with acceleration 1g. It is possible to experience weightlessness for a considerable length of time by turning the nose of the craft upward and cutting power so that it travels in a ballistic…

## What is weightlessness (zero g)?

Weightlessness is the complete or near-complete absence of the sensation of weight. This is also termed zero-G, although the more correct term is “zero G-force”.

## How does weightlessness occur in free fall?

The phenomenon of “weightlessness” occurs when there is no force of support on your body. When your body is effectively in “free fall”, accelerating downward at the acceleration of gravity, then you are not being supported. The sensation of apparent weight comes from the support that you feel from the floor, from the seat, etc.
