CONTENT ANALYSIS
TERMS: Second law of motion
Facts
§ the net
force on an object is equal to the rate of change
(that is, the derivative) of its linear
momentum
§ The second law can also be stated in terms of
an object's acceleration
§ Since Newton's second law is only valid for
constant-mass systems
§ Any mass that is gained or lost by the system
will cause a change in momentum that is not the result of an external force
Concepts
v 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.
v The acceleration of an object as produced by a net force is directly
proportional to the magnitude of the net force, in the same direction as the
net force, and inversely proportional to the mass of the object.
Law
The acceleration of an object as produced by a
net force is directly proportional to the magnitude of the net force, in the
same direction as the net force, and inversely proportional to the mass of the
object.
