A downward force of magnitude 4.00N is exerted on the book by ___________.
An upward force of magnitude ___________ is exerted on ___________ by the hand.
Is the upward force in part (B) the reaction to the downward force in part (A)?
The reaction to the force in part (A) is a force of magnitude ___________, exerted on ___________ by ___________. Its direction is ___________.
The reaction to the force in part (B) is a force of magnitude ___________, exerted on ___________ by ___________. Its direction is ___________.
The forces in parts (A) and (B) are "equal and opposite" because of Newton's ___________ law.
Explanation / Answer
A downward force of magnitude 4.00N is exerted on the book by _earth__________.
An upward force of magnitude _4N__________ is exerted on _____BOOK______ by the hand.
Is the upward force in part (B) the reaction to the downward force in part (A)? YES
The reaction to the force in part (A) is a force of magnitude ____4N_______, exerted on _HAND__________ by _______BOOK____. Its direction is __UPWARD_________.
The reaction to the force in part (B) is a force of magnitude _4N________, exerted on ___BOOK________ by ____HAND_______. Its direction is ______UPWARD_____.
The forces in parts (A) and (B) are "equal and opposite" because of Newton's __3rd _________ law.
