# Question: Can An Object Have Negative Weight?

## What is negative weight cycle?

A negative weight cycle is a cycle with weights that sum to a negative number.

The Bellman-Ford algorithm propagates correct distance estimates to all nodes in a graph in V-1 steps, unless there is a negative weight cycle.

If there is a negative weight cycle, you can go on relaxing its nodes indefinitely..

## Which thing has no weight?

Anything in zero-gravity can have a certain size, shape but will be weightless. Explanation: The weight of a person or an object is actually a force.

## Where the weight of an object is zero on Earth?

Answer. Weight of an object is zero at the centro of the earth as the distance between the object and the centre or the radius of the earth becomes zero. Therefore, the acceleration due to gravity also becomes zero.

## Can particles have negative mass?

Although no particles are known to have negative mass, physicists (primarily Hermann Bondi in 1957, William B. Bonnor in 1964 and 1989, then Robert L. Forward) have been able to describe some of the anticipated properties such particles may have.

## Can an object have a zero weight?

Weight can be zero when acceleration due to gravity is zero. The value of ‘g’ is maximum on the surface of the Earth and decreases on going inside the surface or above the surface of the Earth. Thus, the weight of a body will be zero at the centre of the Earth.

## Do all objects have weight?

In everyday use, as all everyday objects have both mass and weight and one is almost exactly proportional to the other, “weight” often serves to describe both properties, its meaning being dependent upon context.

## What is a negative cost cycle?

A negative cycle is one in which the overall sum of the cycle comes negative. Negative weights are found in various applications of graphs. For example, instead of paying cost for a path, we may get some advantage if we follow the path.

## What is the weight of a body during free fall?

A freely falling object has weight W=mg, where W-weight, m-mass of the object and g-acceleration produced due to the earth’s gravity. An object kept in a lift which falls freely, weighs zero on the weighing machine, but its actual weight is still mg.

## What does a negative weight mean?

It is a weighted graph in which the total weight of an edge is negative. If a graph has a negative edge, then it produces a chain. After executing the chain if the output is negative then it will give – ∞ weight and condition get discarded.

## Is dark matter negative mass?

Dark matter may be an invisible material, but it exerts a gravitational force on surrounding matter that we can measure. … Just like normal matter, negative mass particles would become more spread out as the universe expands – meaning that their repulsive force would become weaker over time.

## Why mass can never be zero even when force is zero?

Whereas on the other hand mass cannot be zero because mass is an intrinsic property and hence it depends upon the object alone and not on other factors. Thus mass of a body cannot be zero.

## What if something has negative mass?

Washington State University physicists have created a fluid with negative mass, which is exactly what it sounds like. Push it, and unlike every physical object in the world we know, it doesn’t accelerate in the direction it was pushed. … “With negative mass, if you push something, it accelerates toward you.”

## Is antimatter negative mass?

Antimatter does not have negative mass. In our universe, there is no such thing as negative mass. Mass only comes in positive form. … Presumably, if negative mass existed, it would be repelled by objects with positive mass such as the earth or sun.

## What is more likely an object with 0 or 0 weight?

It is more likely for an object to have a weight of zero because the weight is the measure of the gravitational force on an object. It is possible to weigh nearly 0 in outer space. Matter, however, is the measure of matter in an object.

## Can a body has mass but no weight?

It is denoted as g. Now for different planets the value of acceleration due to gravity is different. So, for a body to have no weight, the acceleration due gravity must be zero. Hence, it is possible that a body can have mass but no weight.
