How does Newton's First Law show the existence of inertial reference frames? [duplicate]
Newton merely stated the law of inertia as:
An object at rest stays at rest, and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced ...

Are there two competing definitions of "inertia"?
The term inertia is often introduced by stating Newton's first law: An object stays at rest or moves with $\vec{v}=const.$, if the resultant force is zero. This feature of masses is called "...

Why don't we use momentum to quantify inertia?
My understanding of Newton's 1st and 2nd laws have led me to believe that inertia and momentum are the same.
1st law: An external force is required to overcome an object's inertia
2nd law: Force is ...

Why is Newton's First Law not considered a vacuous statement? [duplicate]
How did Newton come to postulate the law of inertia when every inertial body that he was considering was (by his own other hypotheses) being acted on by the force of universal gravitation.
In other ...

Definition of mass
In high school physics, I was taught that mass was just how much "stuff" or matter there is in an object. However, now that I am learning physics again in college, I am taught that mass of an object (...

Inertia Vs Momentum
At my recent lesson on kinematics, my teacher taught about inertia and momentum. This is what she said.
Inertia: a characteristic of an object that resists changes to its state of motion.
Momentum: ...

Newton's first law: is his concept of (force of ) inertia still useful and used?
The force of inertia is the property common to all bodies that remain
in their state, either at rest or in motion, unless some external
cause is introduced to make them alter this state.
That is ...
