Key Concepts:
Chapter 3: Newton’s 1st Law—Inertia
Honors: Analyze the effect of friction, including static and kinetic friciton
Chapter 3: Newton’s 1st Law—Inertia
- Recognize how inertia affects the motion of objects at rest and in motion
- Relate an object’s mass to its inertia
- Relate an object’s acceleration to the net force acting on it
- Relate pressure to the force over the area which it is applied
- For an object in free fall:
- explain how the acceleration is independent of mass
- analyze the effect of air resistance
- Recognize that any force interaction always involves a pair of objects
- Compare the strength and direction of action and reaction forces on each interacting object
Honors: Analyze the effect of friction, including static and kinetic friciton
