- Newtons First Law can be written as the formula

since acceleration is the changing of velocity as its formula is

Thus, a force must be acting on an accelerating/decelerating object
- It is not mass as the mass does not act on the object but rather the mass is acting on the surface of the ground.
- Changing velocity is already acceleration
- inertia is the term used to describe Newtons first law
