Physics Final Exam Review Test with correct solutions A force is needed to The combination of all forces acting on an object is called the When you hold a rock at rest in your hand, you are pushing upward on it with as much force as Earth's gravity pulls down on it. The net force would be The scientific unit of force is the newton-- Tension is a Weight is the force of gravity A vector is an arrow that A vector quantity is a quantity that needs both magnitude and A scalar quantity is a You can express the equilibrium rule mathematically as Mechanical Equilibrium is a Whenever the net force on an object is zero, the object is said to be in What is the Equilibrium Rule? For a suspended object at rest, the forces acting upward on the object must be For an object at rest on a horizontal surface, A support force is the upward force An upward support force is -The weight of a book sitting on a table is a negative force -The atoms squeeze -The compressed atoms produce Objects at rest are said to be in Objects moving at constant speed in a straight line path are said to be in Equilibrium is a state of An object under the influence of only one force
