Question
Can someone please explain why when you have a rope pulling anobject on a frictionless surface with acceleration you don't takegravity into effect as a force?Doesn't gravity act on everything, hence the reason whyeverything isn't floating around.
How much tension must a rope withstand if it is used toaccelerate a 960kg car horizontally along a frictionless surface at1.20 m/s2
I know the answer is 960 x 1.20
but why do I think it is (960 x 1.2 x 9.8) why doesn't (g)effect this equation.
Thanks

Explanation / Answer
Doesn't gravity act on everything, hence the reason whyeverything isn't floating around.
due to equilibrium.
How much tension must a rope withstand if it is used toaccelerate a 960kg car horizontally along a frictionless surface at1.20 m/s2
F=ma=960*1.2N
I know the answer is 960 x 1.20
but why do I think it is (960 x 1.2 x 9.8) why doesn't (g)effect this equation.
as i mention as answer for the first part g=9.8will act when the body is moving in the verticaldirection.
