Reference: WJEC
Governs the dynamic response of a particle of constant mass m subjected to an unbalanced resultant force, where the acceleration is directly proportional to the net resultant force and acts in the identical direction.
The resultant force on an object is equal to its mass times acceleration, written as F = ma.
The resultant force on a particle equals mass times acceleration, written F = ma.
