Question “A book weighing 5 N rests on top of a table. * A downward force of magnitude 5 N is exerted on the book by the force of…”
A book weighing 5 N rests on top of a table.
* A downward force of magnitude 5 N is exerted on the book by
the force of
a.table
b. gravity
c. intertia
* An upward force of magnitude _____ is exerted on the _____ by
the table. Fill in the blanks
* Do the downward force in Part A and the upward force in Part B
constitute a 3rd law pair?
* The reaction to the force in Part A is a force of magnitude
_____, exerted on the _____ by the _____. Its direction is _____ .
Fill in the blanks
* The reaction to the force in Part B is a force of magnitude
_____, exerted on the _____ by the _____. Its direction is
_____. Fill in the blanks
* Which of Newton’s laws dictates that the forces in Parts A and
B are equal and opposite?
Newton’s 1st or 2nd law or Newton’s 3rd law | |
Answer
a) b.Gavity
b) A force of magnitude 5N is applied to the book at the table.
c) No
D) The reaction to Part A’s force is a force magnitude 5N that the BOOK exerts on the EARTH. Its direction is UPWARD.
E) The force that reacts to Part B is a force magnitude 5N. It exerts its force on the TABLE and the BOOK. Its direction is DOWNWARD.
G) Newton’s third law
Conclusion
Above is the solution for “A book weighing 5 N rests on top of a table. * A downward force of magnitude 5 N is exerted on the book by the force of…“. We hope that you find a good answer and gain the knowledge about this topic of science.
