What is the correct definition of Newton's Law of Inertia

• The acceleration of a body is proportional to, and in the same direction as, the unbalanced force applied to it

• An object either remains at rest or continues to move at a constant velocity, unless acted upon by a some external force

• For every action there is an equal and opposite reaction

What is the equation used in Newton's law of acceleration?

• a = f x m

• f = m x a

• m = f x a

• It is always of a general nature.

• It does not involve the use of numbers.
