Newton’s First Law Is the Law of Inertia
________________ said that objects in motion will stop unless a constant force is applied
to them. Aristotle never ___________ his idea which would not be proven false until the
17th century by _____________. Galileo studied motion scientifically and determined
what _________________ would formalize in his first law: the Law of Inertia. Isaac
Newton was born in the 17th century about 100 years after the death of Galileo. Newton
is one of the most famous scientists in human history for his contributions to the
understanding of motion, gravity, force, and as the co-inventor of _________________,
the mathematics that best describes motion and change.
1. Galileo described ___ states of motion: _____________ & ____ moving in relation to
a _____________ point.
2. Inertia is:
3. The amount of inertia an object has is related to an object’s ___________.
4. Two examples of inertia:
5. Newton’s first law is the law of ___________________. It can be stated as:
6. Forces like _____________ can act on objects and change their state of
_____________. A force is defined as a ____________ or a pull.
6. On the back of this page, write Newton’s first law and illustrate it with a colored
drawing showing an object at rest (stationary) and an object in motion and their resistance
to changes in their inertia. Ex: It’s easy to change the inertia of a baseball and hard to
change the inertia of a cannonball because it takes less force to catch a baseball than a
cannonball.
