Question

Do elastic collisions conserve momentum?
My ans:___Elastic collisions solely occur when there is no net conversion of energy.

Answer 1

@ganeshie8

Answer 2

my thought is to simply make a simple elastic/momentum setup and check it out

Answer 3

Thanks, also. can you tell me if this is an increase or decrease. -0/20m/s to 0 is an increase right, since it's positive?

Answer 4

0/20 = 0 or is their a mistype?

Answer 5

Yes. xD 0.20

Answer 6

is this part of a larger question, where you found these?

as is it looks as if we have a speed of .20 headed in the -x direction, and end up with a speed of 0 headed in the 0 direction

Answer 7

if so, then we have decreases our speed and stopped relative to a linear motion

Answer 8

Momentum lab, it's an inelastic collision.
The red wagon's velocity before the collision is 0.20m/s after the collisions it decreases to 0m/s. The blue wagon's velocity before the collision is -0.20m/s after the collision it increases to 0.

Answer 9

so it has to do with linear motion :)

Answer 10

Yeah yeah, so it stopped. I've been using decrease, and increase. ~sighs~

Answer 11

speed is how fast something moves, and something can never have a speed that is less than 0.

velocity is a measure of speed in a given direction

Answer 12

speed of .20 in the direction of (-1,0) , the speed has to slow down in order to reach 0

Answer 13

Ohh. . . I understand now. Thanks Ami. ~[*~*]~

Answer 14

good luck :)
