That makes no sense. The quantity on the left is a dimensionless coefficient, while that on the right is a mass.μs,k =m+2m+3m
Net force is the overall force acting on an object, taking into account all of the individual forces acting on it. It is calculated by summing up all of the forces in a given direction, taking into account their directions and magnitudes.
The mass of an object does not directly affect its net force. However, a larger mass may require a larger force to produce the same acceleration, according to Newton's second law (F=ma).
We can prove this by conducting an experiment where we measure the net force on both a 2m mass and a 1m mass under the same conditions. We should see that the net force on the 2m mass is twice the net force on the 1m mass, demonstrating that the net force is directly proportional to the mass.
Yes, it is possible for the net force on a 2m mass to be zero. This would occur if all of the individual forces acting on the mass cancel each other out, resulting in a net force of zero.
Yes, the direction of the net force on a 2m mass can change. This would occur if the direction of one or more of the individual forces acting on the mass changes, resulting in a change in the overall direction of the net force.
