Newton's Laws: sublevel 7
1.
The acceleration of an object is
related to the net force exerted upon it and
related to the mass of the object. In equation form:
(a. directly, inversely
a = Fnet / m.
b. inversely, directly
c. directly, directly
d. inversely, inversely
2.
Use Newton's second law to predict the effect of an alteration in mass or net force upon the
acceleration of an object.

An object is accelerating at a rate of 8 m/s² when it suddenly has the net force exerted upon
increased by a factor of 2. The new acceleration will be
m/s?.
