Newton Second Law of Motion  

Mass:
m = F_{net} /a
Acceleration:
a = F_{net}/m
Where,
F_{net} = Net Force
m = Mass
a = Acceleration.
Example:
Calculate the Net Force as per Newton’s Second law of motion for the given details.
Mass (m) = 30 kg
Acceleration (a) = 25 m/s^{2}
Solution:
Apply Formula:
F_{net} = ma
F_{net} = 30*25
F_{net} = 750N
Net Force (F_{net}) = 750 N
