Question

Two shopping carts are pushed with the same amount of force. However, one shopping cart has a greater mass than the other.



How does the mass of the shopping carts affect their acceleration?



A.
The shopping cart with the most mass will accelerate less than the shopping cart with the least mass when the same force is applied.


B.
The shopping cart with the most mass will accelerate more than the shopping cart with the least mass when the same force is applied.


C.
Both shopping carts will accelerate at the same rate, since it is force and not mass that determi

Answer 3

What is C and D?

Answer 4

from the Newton's second law \(F=ma\), acceleration is inversely proportional to the mass
so as the mass increases, the acceleration decreases..
so which one do you think is the best answer?

Answer 5

C?

Answer 6

nope, remember the other shopping cart has a GREATER mass than the other one, which means that the acceleration will be? (remember the second law)

Answer 7

i don't see any "D" from the choices
and btw, don't guess , try to understand it, this will help you a lot ;p

Answer 8

B?

Answer 9

why "B" ?

Answer 10

yeah, you got the point, the accelerate will decrease... but read choice "B" again, does it follow your point?

letter b says that if the mass is greater, the acceleration will increase, which doesn't make sense
do you get what i mean?

Answer 11

yeah i understand now its A

Answer 12

are you sure?

Answer 13

yes

Answer 14

can you explain why?


(i'm just making sure that you are not guessing :))

Answer 15

yeah sure...because If you double the mass then the acceleration is halved, with the same force. Also from the Newton's second law F=ma, acceleration is inversely proportional to the mass so as the mass increases, the acceleration decreases.

Answer 16

yes!! right! ^_^

Answer 17

Thanks!
