strictly speaking, in a=f/m the units for a are (m/s)/s
example: apply a force of 1000 n to a mass of 100 kg, this will result in an acceleration of 1000/100 = 10 (m/s)/s , meaning its velocity will increase by 10 m/s every second
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.
Every single object that exists obeys ALL of Newtons Laws
Newtons Second Law was F=ma, means the force(F) acting on object is equal to mass(m) of object times it's acceleration(a).
Newton's second law is F=ma where 'F' is Force (in newtons, N), 'm' is mass (in kilograms, kg) and 'a' is acceleration (in meters per second per second, ms^-2) you can replace the symbols in the equation with their respective units: N = kg * ms^-2 so one newton is equal to one kilogram-meter-per second-per second.
F=ma Input: newtons second law at wolframalpha.com
newtons * meters squared / coulombs squared
Its a matter of being scientifically rigorous. You can not claim the 2nd law as a law unless you first establish the first law.
The original formula Force=(mv-mu)/twhere m-mass, v- final velocity, u- initial velocity, t- timeThe derived form Force= mass x acceleration
its not importsnt
Gravity exerts a force; the Second Law states that such a force will cause an acceleration, which can be calculated as:a = F/m (acceleration = force divided by mass).
This is because two concepts are derived from the newtons second law. First : Force . F = m * a Second : momentum .. p = m * v
The clue is in the question.
the second law
59 seconds because of Newtons 1st law of gravity an hour is originaly 60 seconds but is repeatedly proven by scientists that when traveling a minute actually takes 59 seconds and that is why clocks are always one second ahead.
Actually, the first one is completely independent on the second one. But the second one doesn't make any sense without the first one.
