Answer:

(a)

Explanation

  • Newtons First Law can be written as the formula

[tex]f = ma[/tex]

since acceleration is the changing of velocity as its formula is

[tex] \frac{v2 - v1}{t} [/tex]

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
