WebbAnswers: See answers and explanations below. 16. C - As the helicopter blades spin and push air in one direction, the air pushes the blades in the opposite direction; the result is that the helicopter can begin to rotate about the axis of the blade. To counteract this rotation, a second set of blades is required. 17. WebbNewton's first law says that if the net force on an object is zero ( \Sigma F=0 ΣF = 0 ), then that object will have zero acceleration. That doesn't necessarily mean the object is at rest, but it means that the velocity is constant. In other words, constant zero velocity—at …

The first law states that a body at rest will stay at rest until a net external force acts upon it and that a body in motion will remain in motion at a constant velocity until acted on by a net external force. Net external force is the sum of all of the forcing acting on an object.
