1. Page 48: Inertia Lab Write all instructions first.
Copy the chart from below on page 43.
1 person from the group, get 8 dominos and a ruler from the front.
another person from the group get 3 books from the front
Each team member will attempt to shoot the bottom domino into the books with out knocking the stack over. You may adjust the stack after each attempt. If the dominos fall your turn is over.
Team Member
Number of Successful shots

When a shot was successful, why did the dominos not fall?
When a shot was unsuccessful, why did the dominos fall?
What is Newton's first law of motion?

4. Why is Newton’s 1st law of motion sometimes called the law of inertia?
Essential Question:
Why is Newton’s 1st law of motion sometimes called the law of inertia?

5. Newton’s 1st law:
An object at rest remains at rest and an object in motion maintains its velocity unless it experiences a net force.
Examples: Bowling ball, baseball, turning car.
Inertia: the tendency of an object to resist any change in motion.
All matter resists any change in motion.

6. Newton’s 2nd Law of motion
The unbalanced force acting on an object is equal to the objects mass times its acceleration.
F = ma
If an equal force is applied to 2 different masses the larger mass will accelerate less.
Force is measured in Newton's (N).

7. Newton’s 2nd Law of motion
Acceleration depends on force and mass.
Example pushing a car.
Example math:
What is the force of a 1,600 Kg car accelerating at a rate of 2.0 m/s2? F= m= a=

8. LSA: page 48. 1st and 2nd Law questions.
Give 2 example of Newton’s 2nd law.
Explain how the law of inertia relates to seatbelts.
Predict what will happen when a car tries to turn on an icy road.
A ball accelerates downward at 9.8m/s2. If the gravitational force is 1.4N, what is the mass of the ball?
The net force on the propeller of a 3.2 Kg model plane is 7.0 N. What is the acceleration of the airplane?
What is the force is needed to accelerate a 10.0 Kg bowling ball forward at 5.0 m/s2?
