Hey guys.... can some one explain me what a newton is, and how do I find net force step by step...thank you.

Question

fretje · Answer

The Newton is the Force a body of 1kg undergoes when it is accelerated by 1m/s2 .  So unit  of Newton is 
$$N = kg.\frac{m}{s^2}$$

anonymous · Answer

whats confusing me is M/^2 I mean, thats really fast... but thanks any way.

fretje · Answer

what is confusing you?

anonymous · Answer

metre per secon squared

anonymous · Answer

so after you multiply the kilogram, what do you do?

anonymous · Answer

I'm trying to find out How much net force is required to accelerate a 1000 kg car at 5.00 m/s2

fretje · Answer

metre per secon squared means every second, the speed goes up with one meter per second, so with one Newton, the kg goes after first second 1m/s, after 2s 2m/s, after 3s 3m/s and so on.  It is comparable to about  one tenth of the gravitational acceleration which is 9,8 m/s

anonymous · Answer

oooh, so if you had 2 metres it would be 2 seconds....ok..

fretje · Answer

Sir Isaac Newton had a rule to calculate any force:
F (the force) = m.a (is the mass in kg, times the acceleration in m/s2)

aaaahhh, ok, I finally get it, thank you!

fretje · Answer

I'm trying to find out How much net force is required to accelerate a 1000 kg car at 5.00 m/s2

So F=m.a = 1000kg.5.00m/s2 = 5000 Newton
