A stone is shown at rest on the ground
a vector shows the weight of the stone. complete the vector diagram showing another vector that results in zero net force on the stone.
b. what is the conventional name of the vector you have drawn
To complete the vector diagram showing another vector that results in zero net force on the stone, you would need to draw a vector of equal magnitude in the opposite direction of the weight vector. This vector is usually referred to as the "support force" or "normal force."
The conventional name of the vector you have drawn is the "normal force." It represents the force exerted by a surface to support the weight of an object resting on it. In this case, the normal force balances out the weight of the stone, resulting in a net force of zero.
To complete the vector diagram showing another vector that results in zero net force on the stone, we need to consider the properties of forces acting on the stone.
The weight vector represents the force of gravity acting on the stone, which is directed vertically downward towards the center of the Earth. To counteract this force and achieve zero net force, we need to draw another vector equal in magnitude but opposite in direction to the weight vector.
Therefore, we draw a vector of equal length and pointing upwards from the stone. This vector represents the normal force, which is the force exerted by the ground on the stone in a direction perpendicular to the surface. The normal force is equal in magnitude but opposite in direction to the weight force and keeps the stone at rest on the ground.
The conventional name for the vector we have drawn is the "normal force."
An upward "normal force" vector is exerted by the ground upon the stone.
The net force is zero, so that the stone does not move.
