Newton’s Second Law (Acceleration)
Newton’s Second Law (Acceleration)
Newton’s second law is the cornerstone of dynamics: force equals mass times acceleration.
Rearranged, a = F/m. where F is the net force and m the mass.
Inputs
F := 1200 N=1200 N
m := 80 kg=80 kg
Divide net force by mass.
a := F/m=15 m/s^2
Results
A larger force or smaller mass gives more acceleration. Only the net (resultant) force matters — balanced forces produce none.
Assumptions & limitations
- Constant mass.
- Net (resultant) force.
- Inertial reference frame.
