FC: Summing Forces
1: Force is a push or pull on an object.
3: Forces are perceived as pushes or pulls, this can provide an intuitive understanding for describing forces
4: Force is that physical quantity which changes or tends to change a body's state of rest or of uniform motion in a straight line
5: When the resultant of a group of forces acting on the same object is zero, the forces are balanced. When the resultant is not equal to zero, the resultant is an unbalanced force.
