Newton’s second law implies that the rate of change in momentum of any object directly corresponds with the resultant force applied and is in the direction of the resultant force. why is Newton’s second law interesting?
Homework Answers
It is interesting as if object is moving with constant velocity then it has no change in monentum so force acting on it is 0
If external applied force on an object is 0 then it moves with constant speed or remains at rest
Please rate it up thanks :)

Newton’s second law relates an object’s acceleration to its mass and the net force acting on it. Does Newton’s second law apply to a situation in which there is no net force? Select the best explanation. A. Yes. The law applies and it tells us that the object has a nonzero acceleration. B. No. The law applies only to situations in which a net force acts. C. No. The law does not apply because a zero net force would produce...

The sum of the forces on an object is directly proportional to
the mass of the object and directly proportional to the
acceleration of the object. The second law is expressed by the
equation: (1) F=ma
If the mass is in kg and the acceleration in m/s2,
then the force is in Newtons.
In (1), F is the net applied force, m is the mass of the object
on which the force is applied, and a is the acceleration of...

Learning Goal: To understand
the relationship between force, impulse, and momentum. The effect
of a net force ΣF⃗ acting on an object is related both to the force
and to the total time the force acts on the object. The physical
quantity impulse J⃗ is a measure of both these effects. For a
constant net force, the impulse is given by J⃗ =F⃗ Δt. The impulse
is a vector pointing in the same direction as the force vector. The
