WebFree-body diagrams are diagrams used to show the relative magnitude and direction of all forces acting upon an object in a given situation. A free-body diagram is a special example of the vector diagrams that were discussed in an earlier unit. These diagrams will be used throughout our study of physics. The size of the arrow in a free-body ... the yellow and green

WebThe work we do on the rock also equals the rock’s gain in gravitational potential energy, PEe. W = P E e = m g d. Kinetic energy depends on the mass of an object and its velocity, v. K E = 1 2 m v 2. When we drop the rock the force of gravity causes the rock to fall, giving the rock kinetic energy. WebThe purpose of adding force vectors is to determine the net force acting upon an object. In the above case, the net force (vector sum of all the forces) is 0 Newton. This would be expected for the situation since the object (the ring in the center of the force table) is at rest and staying at rest. We would say that the object is at equilibrium ... Weba. all the forces acting on an object are balanced. b. the sum of the + x forces on an object equals the sum of the – x forces. c. the net force on the object is zero. d. the sum of the upward forces equals the sum of the downward forces. e. all of the above ____ 35.
