Question

Can someone please help me with this..

Answer 1

"If the mass of an object is tripled, and the force acting on it is doubled, how will the object's acceleration be affected?"

I can't decide whether the acceleration would be double it's original value, or if it would be 2/3s of its original value. Can someone please explain this to me?

Answer 2

F = ma :P

Answer 3

Would it be 2f = 3ma?

Answer 4

exactlY!

Answer 5

So if you triple the mass, then you have to multiply the acceleration by something that will end up equaling two, f=ma, so 3*2/3=2. And the force is doubled.

Answer 6

I thought that the acceleration would be 2/3 of it's original value, because F=ma would be 2f = 3m * a, and you would need to divide both sides by 3 to get 2/3f = a?

Answer 7

i would say

2f = 3ma' (i use a prime because this is new acceleration)
so now compare the two equations and get a' in terms of a!

Answer 8

thats correct!

Answer 9

Ok, thank you for your help :)

Answer 10

No problem!
