Can mass and weight equal zero?

W = m ∗ g W = m * g W=m∗gComparing Mass and Weight. Mass can never be zero. Weight can be zero if no gravity acts upon an object, as in space. Mass does not change according to location.

Is mass can be zero at the Centre of the earth?

At the centre of the earth, the acceleration due to gravitiy is zero, so weight of the body at the centre of earth is zero.

Can a body have zero mass and non zero weight?

Answer: A body can have zero weight, but not zero mass. If g is 0 (center of the Earth 0, then weight will also be zero. But mass is the total number of atoms in a body.

Why is gravity at center of earth zero?

Acceleration due to the earth’s gravity is zero at the centre of the Earth because at that point the mass of the earth is equally distributed in all directions, so pulling equally in all directions for a net zero pull. As the distance from the centre decreases, the acceleration due to gravity also decreases.

Why weight of the body is zero at the Centre of the earth?

By definition, the weight of a body is defined as the force by which the body is attracted by the earth’s gravitational pull towards the center of the earth. Thus, weight is zero where the acceleration due to gravity is zero. Hence, the weight of the body placed at the center of the earth is zero.

Can the mass of a body ever be zero?

The mass of a body is can be zero whereas the weight of a body can never be zero. True or false. > The mass of a body is can b… The mass of a body is can be zero whereas the weight of a body can never be zero. True or false.

What is the mass of an object with zero rest mass?

The word “mass” nowadays means “rest mass”. That is the mass of an object as measured by an observer with the same velocity as the mass. An object may have zero rest mass. Then, it can only move at the speed of light. The only known objects with zero rest mass are photons and (theoretically) gravitons.

Why do we assume a photon has zero mass?

There are justifications for why we assume the photon has zero mass. The photon only has 2 degrees of freedom; the longitudinal polarisation does not exist precisely because the photon is massless. We also have other reasons to believe the photon is massless.

Can your weight be zero in space?

In places where g is zero (like outer space) or where you are in continuous free fall (like ISS, but this condition is not fully weightless, hence it is called microgravity) or when your body’s weight is balanced by some other external force (Your weight is the force exerted by your mass on earth) your weight can be zero.
