1. Newton’s 1st and 2nd Laws of Motion
Chapter 2, Section 3
Page 51 – 54

2. The 1st Law of Motion
An object at __REST__ will remain at rest, and an object moving at a __CONSTANT__ velocity will continue moving at a constant velocity, unless it is acted upon by an __UNBALANCED FORCE__.
Non-moving objects will __ NOT__ moving.
A moving object will __KEEP__ moving
__GRAVITY and FRICTION__ are 2 forces that change an object’s motion.
In your own terms: ___AN OBJECT AT REST WILL STAY AT REST, AND AN OBJECT IN MOTION WILL STAY IN MOTION, UNLESS AN OUTSIDE FORCE ACTS ON IT__.
Newton’s 1st Law of Motion (1:32)

3. Inertia
__INERTIA__ is the tendency of an object to resist a change in motion.
Newton’s __1st LAW__ is also known as the Law of Inertia.
Inertia Depends on Mass
The GREATER the mass = The __GREATER__ the inertia.
The LESS the mass = the __LESS__ the inertia.

4. The 2nd Law of Motion
Acceleration depends on the object’s __MASS and NET FORCE__ acting on the object.
Acceleration = __NET FORCE__ / __MASS__
Acceleration is measured in __METERS PER SECOND PER SECOND (M/S2)__
Mass is measured in __KILOGRAMS__
Force is measured in __KILOGRAMS (Kg) X M/S2 __ or __NEWTONS__
2nd Law of Motion (3:08)

5. Changes in Force and Mass
Two ways to increase the acceleration of an object: __FORCE__ and __MASS__
For a constant mass:
__MORE__ force =
__MORE__ acceleration
__LESS__ mass =
