net force | combination of all forces acting on an object |
newtons first law of motion | states that objects at rest will remain at rest or move with a constant velocity unless forceis applied |
newtons second law of motion | states that object acted upon by a net force will accelerate in the direction of the force |
newtons third law of motion | states that force always act in equal but opposite pairs |
terminal velocity | constant speed of an object reached when the force of gravity is balanced by air resistance |
unbalanced forces | two or more unequal forces acting on an object causing the object to accelerate |
weight | the gravitational force between you & earth |
