Newton's Second Law: F = ma
The Newton's Second Law states that the force acting on an object in a straight line is directly proportional to the magnitude of the object's mass and inversely proportional to the square of the object's velocity. In other words:
F = ma
Where:
F is the force in newtons (N)
m is the mass in kilograms (kg)
a is the acceleration in meters per square second squared (m/s²)
Examples:
If a force of 10 N is applied to a 2 kg object, the object will accelerate with an acceleration of 5 m/s².
If a 5 kg object is moving at 10 m/s, and a force of 20 N is applied, the object's acceleration will be 4 m/s².
If an object has a constant velocity of 2 m/s, then the force acting on it must be zero for the object to stay motionless
