## Can a body have mass but zero weight explain your answer?

Yes, a body can have mass but no weight at the centre of the earth. This is because acceleration due to gravity (g) decreases as we go deep into the earth and becomes zero at the centre.

## Can a mass of body be zero?

Now as we know that the mass of any body does not depend on any parameter it is dependent only on the object i.e. body because mass is an intrinsic property. So the mass of a body can never be zero.

**Can an object’s weight be zero?**

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.

### At which place the weight of a body Cannot be zero?

the earth

Thus on the surface of the earth a body weighing 1kg has a weight equal to 9.8N independent of its state of motion. Hence a body at the surface of the earth cannot be zero since the value of g at earth surface is 9.8N.

### Can a body have no weight if mass is there how?

The value of acceleration due to gravity is on an average taken as 9.8ms−2 . 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.

**What has mass but no weight?**

In scientific contexts, mass is the amount of “matter” in an object (though “matter” may be difficult to define), whereas weight is the force exerted on an object by gravity. Similarly, a balloon has mass but may appear to have no weight or even negative weight, due to buoyancy in air.

#### Can weight be zero even when the mass of the object is not zero?

weight of the body is actually the gravitational force acting on it and mass of a body is the no. of particles present in it. therefore weight can be zero but mass can never be zero.

#### In which condition can a body with fixed mass have zero weight?

Weightlessness is the condition in which the weight of the body seems to be zero. A body with a fixed mass will be weightless under the following conditions: When a body falls freely under the influence of the force of gravity only. When the acceleration of a falling body is equal to the acceleration due to gravity.

**Can weight be zero even if the mass of the object is not zero?**

Answer and Explanation:- Weight of the body is actually the gravitational force acting on it and the mass of a body is the no. therefore weight can be zero but mass can never be zero.

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

zero

Neglecting air resistance, there are no other contact forces on a body during free fall and hence, its weight is zero.

## Can a body of mass M have weight equal to zero?

Therefore, weight of the body in space is zero even though the body has a mass. Weight (W) is the force experienced by a body when it comes in the periphery of gravitational field of a heavenly body. Numerically weight is equal to the product of mass (m) of the body experiencing force and acceleration (g) due to gravity.

**How is the mass of a body related to its weight?**

Weight (W) is the force experienced by a body when it comes in the periphery of gravitational field of a heavenly body. Numerically weight is equal to the product of mass (m) of the body experiencing force and acceleration (g) due to gravity. If g=0 with mass of body equals to m (non-zero). Weight of body will be zero.

### Are there any objects with zero rest mass?

The only known objects with zero rest mass are photons and (theoretically) gravitons. (Gravitons are quanta of gravitation, and exist according to generalization of quantum mechanics to gravitational waves, but there is no more direct way to observe or infer their existence.) The word “mass” nowadays means “rest mass”.

### How is the weight of matter dependent on the frame of reference?

Weight is dependent on the frame of reference but mass is absolute as matter cannot be created or destroyed. If you are in space and stand on a weighing machine, it would indicate a weight of zero. If you are inside an elevator and the elevator starts free falling, and then you stand on a scale, the scale will read zero.
