Question

As an object falls freely toward the earth, the momentum of the object-earth system (1) decreases (2) increases (3) remains the same

Answer 1

what is the equation for momentum?

Answer 2

p = ?

Answer 3

p = mv p is momentum

Answer 4

good, now can you describe v in terms of free fall to earth?

Answer 5

v = p/m ?

Answer 6

no using other equations you know? Newtonian laws perhaps?

Answer 7

wait, what's the answer first of all?

Answer 8

think about it for a while...what happens to the velocity as you fall toward the earth?

Answer 9

what are you doing when you fall down, are you at a constant velocity?

Answer 10

yea

Answer 11

u there

Answer 12

yes, and no you are not falling at a constant velocity...you should google what gravity is. F=ma?

Answer 13

yea
