s you collect plastic bottles for recycling, one of the bottles rolls horizontally off the kitchen counter and bounces on the floor about 1 foot (0.3 meters) outward from the base of the counter. Why didn't the bottle drop straight down and hit the floor exactly at the base of the counter?1 pointThe bottle coasted horizontally outward as it fell vertically.The counter pushed the bottle horizontally outward as the bottle fell vertically.The bottle pushed itself horizontally outward as it fell vertically.The direction of the net force on the falling bottle was at an angle between outward and downward, so the bottle moved outward and downward.

Solution

The bottle didn't drop straight down and hit the floor exactly at the base of the counter because it coasted horizontally outward as it fell vertically. This is due to the initial horizontal velocity the bottle had when it rolled off the counter. While gravity pulls the bottle downward, the bottle continues to move in the direction it was going when it left the counter, which is outward. This is an example of projectile motion.

9. If the bottle were left open (with no cap) and additional force were applied to the bottle—such as someone pulling it downward as it fell—what would you expect to see happen? aThe water would stay in the bottle.bThe water would come out of the top of the bottle.cThe water would come out of the holes in the bottle sideways.dThe water would come out of the holes in the bottle and fall downward.

8. Why was less water lost (on average) when the bottle fell for about 1 second than when it remained motionless for 1 second? aThe water becomes weightless as it falls.bThe bottle and the water are both attracted to Earth by gravity at the same rate.cThe water does not fall as quickly as the bottle because the bottle encounters more air resistance.dThe gravitational force on the water is more than the force on the bottle because the water has more mass than the bottle.

. Which of the following is the BEST interpretation of the differences between the bottle being dropped and the water being released while the bottle was held still? aThe water will always move downward out of the bottle.bThe water will fall at different rates depending on how the bottle does or does not fall.cWhen the bottle is motionless, gravity will attract the water downward out of the bottle.dThe water will squirt out sideways because of the pressure of water farther up in the bottle.

If a crumpled piece of notebook paper and a flat sheet of notebook paper are dropped at the same time from the same height, why does the crumpled piece of paper land first?A The crumpled paper has more gravitational force exerted on it.B The flat paper has more air resistance.C The flat paper has more mass.D The crumpled paper has less mass.
