No, but it can get fairly close to zero.
No, it is not possible for an object's mass to be zero.
If an object's mass is exactly zero, then the object does not exist. No mass means no atoms. However, an object can have no weight and still have a mass. The weight depends on the gravitational force.
A stationary object has zero momentum since momentum is the product of an object's mass and its velocity. In this case, since the object is not moving, its momentum is zero.
Density is simply mass divided by volume, so that would mean either that the object has zero mass, or that it has a huge extension.Density is simply mass divided by volume, so that would mean either that the object has zero mass, or that it has a huge extension.Density is simply mass divided by volume, so that would mean either that the object has zero mass, or that it has a huge extension.Density is simply mass divided by volume, so that would mean either that the object has zero mass, or that it has a huge extension.
We don't think you can. Here's our reasoning: -- Kinetic energy of an object is [(1/2)(mass)(speed)2]. If kinetic energy is not zero, then mass can't be zero, and speed can't be zero either. -- Momentum of the object is [(mass)(speed)]. If mass isn't zero and speed isn't zero, then momentum isn't zero.
An object at rest has zero momentum. For example, a stationary rock on the ground has zero momentum because both its mass and velocity are zero.
When an object is still it has no momentum. That is, the momentum is zero.
No, a stationary object does not have momentum because momentum is the product of an object's mass and its velocity. If an object is not moving (velocity is zero), then its momentum will also be zero.
An object does not have momentum when it is stationary or not in motion. Momentum is a product of an object's mass and velocity, so if either of these values is zero, the object's momentum will also be zero.
No, a resting object does not have momentum because momentum is the product of an object's mass and velocity. Since a resting object has zero velocity, its momentum is also zero.
An object at rest has zero momentum because momentum is the product of an object's mass and its velocity, and if the velocity is zero, then the momentum is also zero.
If the net force on an object is zero, then the object is in equilibrium. This means there are balanced forces acting upon it, or none at all.
