According to Newton’s 2nd Law... (Science Homework Help!)?

Question

i) What happens to acceleration if mass is doubled?
ii) What happens to acceleration if the net force is doubled?
iii) What happens to acceleration if force is tripled and mass is halved?

This is one of the only questions in my homework I'm not sure about... anyone know? Thanks!

Answer 1

F=mxa
m= F/a
a= F/m

plug into equation

i) a=F/2m (decreases by 1/2 times)
ii) a=2F/m (increases by 2 times)
iii) a= 3F/(1/2m) (increases by 6 times)

Answer 2

My college physics professor told our class that if the mass of an object doubles the force on that object doubles but it's acceleration remains the same. But as far as the other questions are concerned I can only tell you my best guess. My calculus based physics text states that "the acceleartion of an object is directly proportional to the net force acting on it". Therefore, I would respond to part 2 of your question by saying that if the net force of the object doubles than the acceleration doubles as well. I'm not sure of the answer to the last question.

Answer 3

it particularly is mind-blowing how absurd you may get in one in each and every of those small area. try certainly analyzing all of what you place on the website. 1st regulation - In different words the universe constantly existed. it ought to no longer have been "magically" created it had to constantly exist so it particularly is in a constantly recycling technique. the great bang, a universe a huge cave in and then yet another great bang, advert infinitum. thank you for PROVING god is un-mandatory. 2d regulation. try analyzing the full regulation, it says in a closed equipment. The earth/sunlight/equipment is an open equipment the place ability is enter. in case your "interpretation" of the little which you study substitute into precise then wood ought to no longer and would not improve. they ought to get an ability enter from someplace - the sunlight - so we are no longer an entropic equipment. try certainly information what you spew previously you do then you certainly won't look so absurd. then this universe won't be able to have existed constantly you're suitable, subsequently the great bang and great cave in. Now study Psalm 102:25-27. Now study the Earth Chronicles, by using Zecharia Sitchin and are available across from the place the bible substitute into plagiarized. all people who's certainly searching for the very fact, please carry out a little genuine analyze previously taking suggestion from silly atheists. try certainly analyzing something different than poorly accomplished shrink and paste. right this is a technological understanding internet site for then you definately. not greater excuses now ok atheists try certainly analyzing the full regulation particularly than fundie shrink and paste.

Answer 4

Start with the formula. F=MA
F=2ma a =1/2
2F=ma a=2 times
3F=m/2a a=6 times
