Consider the following statement: “The normal force on an object is always equal to the weight of the object.”Select all the reasons that this statement is false .       The normal force is not always parallel to the force of gravity     The normal force is independent of the force of gravity     The normal force is only equal to the weight of the object when sitting on a horizontal surface and there are no other forces in the y-direction except gravity     The normal force causes an acceleration and therefore does not interact with gravity
