If I hold a book and a piece of paper and drop them at the same time, what is going to fall first?

Question

What would happen if I did this experiment on Earth?
What would happen if I did this experiment on the moon?

Answer 1

earth=it would be the book because it weighs more
moon-it would be both

Answer 2

For this, you have some Potential energy being converted into Kenitic energy. The formula for finding these each of these is PE=mass*gravity*height and KE=(1/2)*mass*( velocity^2 ). Also, no energy is lost from going from one to the other, so PE=KE.

Now, when you put these 2 together you will find mass on both sides of the equation, so you can cancel them. gravity*height=(1/2)*( velocity^2 ) So mass has nothing to do with the rate an object falls!

...BUT this is if you are in a vacuum... on Earth the paper would slow down because Kenitic Friction would be very close to the force of the paper ( Force=mass*accel and Kenitic Friction=Friction coefficient*mass*gravity ), but on the moon this Friction_coefficient would be much less and allow it to fall at a greater total force.

Answer 3

The book would fall first because of its weight. Since the piece of paper is light, it will be slowed down by air resistance much more than the book. On the moon, both would fall at the same rate because there is no air resistance.

Answer 4

hahaha yea just drop them

buttt... the book would fall first on earth because it has more mass, so there is more mass for gravity to act on

is there a gravitational force on the moon?? i am pretty sure there is, just not as much as earth. .. if there is, then book falls first again

Answer 5

book
both fall first on moon

Answer 6

if u drop them at the same time then, they will fall at the same time

Answer 7

It would be quicker for you to do this experiment rather than ask Yahoo answers..
