An airplane demonstrates the law of action-reaction becauseA its forward force is balanced by wind resistance while it is cruising.B when it lands, the ground pushes against the plane and slows it down.C the force of its rudder moving to the right turns the plane to the right.D its wings deflect air downward, and the air pushes the plane upward.
Question
An airplane demonstrates the law of action-reaction becauseA its forward force is balanced by wind resistance while it is cruising.B when it lands, the ground pushes against the plane and slows it down.C the force of its rudder moving to the right turns the plane to the right.D its wings deflect air downward, and the air pushes the plane upward.
Solution
The airplane demonstrates the law of action-reaction, also known as Newton's third law of motion, through option D: its wings deflect air downward, and the air pushes the plane upward.
Here's the step-by-step explanation:
-
As the airplane moves forward, its wings are designed to cut through the air and push it downwards.
-
According to Newton's third law of motion, for every action, there is an equal and opposite reaction.
-
So, as the wings of the plane push air downwards (action), the air pushes back against the wings with an equal force but in the opposite direction, i

Which of the following is NOT correct about action and reaction forces?Group of answer choicesan example could be the recoil of a gun after the bullet has been firedan example could be pushing the ground back with our feet, so that ground pushed us forward and we can walkan example could be the upward movement of a balloon after the air has been releasedAll these statements are incorrectAction and reaction are equal and opposite forces and cancel each other.
The "reaction" force does not cancel the "action" force because:Group of answer choicesthe reaction force exists only after the action force is removedthey are in the same directionthe action force is greater than the reaction forcethey act on different bodiesthe reaction force is greater than the action force
