Newton's second law of motion describes the relationship between an object's mass and the amount of force needed to accelerate it.
This law can be expresses as F=ma,
F - force acting on an object m - the mass of an object a - its acceleration
The more mass an object has, the more force you need to accelerate it. And the greater the force, the greater the object's acceleration.
F = ma
=2000*4 = 8,000 N
