QUESTION 1: If you can exert a pull that is greater than your weight, why can’t you fly off the ground by pulling your belt upward?
because the Earth will pull you downward with the same force, so they cancel out
because your body exerts the same amount of force on you, so they cancel out
because the normal force and your weight cancel out just before you pull your belt upward
not enough information is given
QUESTION 2: You are pushing a box to the right with a 210-N force. How much force does the box exert on you?
less than 210 N, to the left
equal to 210 N, to the left
equal to 210 N, to the right
greater than 210 N, to the left
in the "tablecloth trick," a table is covered in a tablecloth and then set with various dishes and vases and other smooth objects. The person performing the trick then quickly jerks on the table cloth in a single fast motion that whips the tablecloth off the table, but leaves the dishes and other objects still in place on the table.
Which of Newton's Laws is most applicable to explain why this trick works?
How do you find the normal force
between a table with a mass of 35 kg and
the floor?
(Assume that normal force and gravity are
the only two vertical forces.)
Your answer:
The normal force is the same
number - 35 kg.
Multiply the mass by the coefficient
of friction.
Multiple the mass by gravitational
acceleration (g = 9.8 m/s²)
The normal force is zero because
the table isn't moving vertically.
The normal force is 9.8 N because it
is on Earth.
