Term
| Newton's Second Law of Motion |
|
Definition
| the relationship between an object's mass m, its acceleration a, and the applied force F is F=ma. Acceleration and force are vectors (as indicated by their symbols being desplayed in slant bold font); in this law the direction of the force vector is the same as the direction of the acceleration vector |
