1. If the net force on an object is O N, the forces are considered unbalanced.
true
false <----
2. Most people in the United States use feet and miles to measure distance in their everyday lives. Why do scientists in the United States use meters to measure distance?
Meters allow scientists t be more accurate in their measurments. <----
Science requires special measurements that are not used in everyday life.
All scientists use meters to measure distance to help eleminate confusion.
Meters are better than feet for measuring objects in motion.
3. Which of the following forces causes a feather to fall slower than a bowling ball?
gravity
rolling friction
sliding friction
air resistance <----
5. Which of the following pairs of objects would have the strongest gravitational pull?
two tall buildings in the same city
two tall buildings in different cities
two stars very far away from each other
two stars very close to each other <----
6. A maglev train uses powerful magnets to lift the train above the track as it moves forward. Such a design reduces which of the following forces?
rolling friction <------
gravity
air resistance
fluid friction
7. Which of the following examples does not demonstrate a change in velocity?
An elevator slows down in order to stop at the top floor.
A cruise shop travels west at a constant speed <----
A soccer ball is passed across the field
A train remains at a constant speed as it moves around a bend.
8. Which of the follwing does not need to be measured in order to describe motion.
size of the object <---
distance the object traveled
velocity of the object
acceleration of the object
