From's Newton's second law of motion:
F=ma
or, F=m(v-u)/t
or, F=(mv - mu)/t
or,Ft=mv - mu
where F=force, m=mass, v=Initial Velocity, v=Final Velocity, t=time
The above equation could be called Newton's first law of motion when u=v and F=0. So it could be concluded that a body of mass m would continue in a state of uniform motion(i.e it would move with Initial Velocity u) over a time t seconds
such that no external force acts on it(as F=0). When the body is at rest(i.e when u=v=0) then also it would remain at rest over a time t.
By second law of motion, F is directly proportional to m, the mass and acceleration "a".
F = k .m .a
where k is the constant of proportionality.
a = F / k .m.
when a = 0,
F = 0 as m cannot be infinite.
hence, if a body is at rest or in uniform motion, a = 0. thus the body remains in its state of rest or uniform motion.
which is the first law.
Law of inertia.
On Earth force in newtons equals roughly mass in kilograms x 9,8 newtons per kilogram. Force in newtons = mass in kilograms times 9.8 or mass in kilograms = force in newtons / 9.8. 73 kilograms are 715 newtons.
Inertia is a sporting example of newton's first law of motion.
newtons first law. An object in motion stays in motion. Its inertia keeps it going
Albert Einstein
This is because two concepts are derived from the newtons second law. First : Force . F = m * a Second : momentum .. p = m * v
Its a matter of being scientifically rigorous. You can not claim the 2nd law as a law unless you first establish the first law.
Actually, the first one is completely independent on the second one. But the second one doesn't make any sense without the first one.
yeah.
The force the other team will have to overcome to win is the sum of the forces exerted by you and your friend, which is 3 newtons + 8 newtons = 11 newtons. So, the other team will have to exert a force greater than 11 newtons to win the tug of war.
His First Law and Second Law both do.

the law of inertia
It isn't.
Force.
To convert grams to newtons, the formula is: Newtons = mass (in kg) * 9.81 m/s^2 (acceleration due to gravity). First, convert 750 grams to kilograms by dividing by 1000: 750 g / 1000 = 0.75 kg. Then, multiply 0.75 kg by 9.81 m/s^2 to find the number of newtons: 0.75 kg * 9.81 m/s^2 = 7.36 N. Therefore, there are 7.36 newtons in 750 grams.
newtons first law: she will not move unless an outside force acts upon her, like her feet moving or her partner moving her!
