1. a sheet of paper because it has a wider area
2. The difference in weight doesn't affect the time, but they are affected differently by air resistance.
3. 4.0 seconds
4. The objects will fall at the same time because gravity will have the same affect on them.
Which has more air resistance: a flat sheet of paper or a paper airplane?
a paper airplane because it has a less wide area
a sheet of paper because it has a wider area✅
a paper airplane because it has a wider area
a sheet of paper because it has a less wide area
A shoe and a shirt are released from the same height. They take different amounts of time to fall to the ground. How can this be explained?
The difference in weight doesn't affect the time, but they are affected differently by air resistance.✅
The weight is equal on the two objects, but there is more air resistance on the shoe.
The weight is greater on the shoe than on the shirt, but there is equal air resistance on the objects.
The masses of the two objects are the same, but they are affected differently by air resistance.
Rock 1 Rock 2
Mass (kg) 2.5 25
Height of Fall (m) 78.4 78.4
Time to Fall (s) 4.0 ?
Based on this data, how many seconds will it take rock 2 to fall?
40 seconds
4.0 seconds✅
1.6 seconds
A hammer and a feather are dropped from the same height by an astronaut on a planet without air. How will their falls compare?
The hammer will fall faster because gravity is pulling it down with a greater force than it is pulling the feather.
The feather will fall faster because it has less mass, allowing it to speed up more easily than the hammer.
The objects will fall at the same time because gravity will have the same affect on them.✅
The objects will fall at the same time because gravity is not acting on them, so they will be affected the same.

thx brah
correct my guy
Thanks a lot. Your answers did really help me to study.
100 % thx
thx
Thanks Emmaline, I got 100%%
ummmm wut about question 5
The minivan and the SUV fall at close to the same speed, while the race car falls faster because of it has less air resistance
it really is a trick question

niceeeee 100%
@emmaline is 100% correct
thnx
Thank you emmaline! :D
