- 10. Multiple Choice
In class, we are investigating Newton's 2nd Law of motion. We measure the force applied to move a textbook across the desk. The textbook has a mass of 2kg and the force measured is 4 N. The textbook moved across the table with a constant acceleration. Which statement best describes why this happened?
The force measured was the force of friction and without friction the textbook accelerates at 2 m/s2
The force measured was the net force and without this force the textbook would have moved faster.
The force is the force of gravity and without this force the textbook would not move.
The force is the net force to the right, which causes the textbook to move at a constant acceleration.

What is weight?
It is how much stuff is inside the object.
It is different for objects depending on the mass and volume.
It is different for objects depending on the mass and gravity.
It is how heavy an object is based on position.

Jessica wants to jump out of an airplane for her birthday. Jessica has a mass of 150 kg once she is suited up. As she falls the force of gravity, which is 1000 N, pulls her down while air resistance, which is 300 N, pushes her up. These forces are _______________.
net forces
balanced forces
unbalanced forces
don't matter
- 13. Multiple Choice

- 14. Multiple Choice
When a ball is rolling down a hill, it will slow down because
the force of gravity slows it down.
the force of air resistance slows it down.

- 15. Multiple Choice
An airplane is transporting supplies for the military troops and the serviceman forgets to close the main cargo door before take off. A crate containing canned goods and a crate containing tissue paper fall of the airplane. Which statement best describes what will happen?
The crate with tissue paper will hit the ground first because it has more mass.
The crate with the canned goods will fall slowly because it has more mass.
The crate with the canned goods will fall quickly because it has more mass.
Both crates will fall at the same rate since they fell at the same time
