Description :
|
|
Newton's second law of motion pertains to the behavior of objects for which
|
|
all existing forces are not balanced.
|
|
The second law states that the acceleration of an object is dependent upon two variables
|
|
- the net force acting upon the object and the mass of the object.
|
|
The acceleration of an object depends directly
|
|
upon the net force acting upon the object,
|
|
and inversely upon the mass of the object.
|
|
As the force acting upon an object is increased,
|
|
the acceleration of the object is increased.
|
|
As the mass of an object is increased, the acceleration of the object is decreased.
