Newton’s 1st Law of Motion: Life and Death before and after Seat Belts

Do Now:

Describe why different objects have different inertia?

Use Newton’s 1st Law to describe why using a seatbelt is necessary for safety in riding in cars.

January 17, 2012HW: 3.2 PTG #1-7, Skip 4, pg 274 Due Mon

Learning Objectives: Explain how Newton’s 1st Law applies to

collisions between objects Apply the relationship between pressure,

force and area to different situations Process skill: Make a prediction based on

the question using both the independent and dependent variable

Success Criteria: Define Newton’s 1st Law Describe how inertia relates to mass and

velocity of an object Explain the forces in a collision, Identify the

relative magnitude and direction Explain how seatbelts work according to

Newton’s 1st Law Describe how different widths on a seatbelt

makes it more/less effective and why Explain the relationship between pressure,

force, and area

Essential Questions

Use Newton’s 1st law to explain why a passenger keeps moving when a vehicle suddenly stops.

What evidence do you have from your experiments that collisions at higher speeds will have greater effect on the passenger?

How does what you learned in this section help you design a safety device for a collision even though you don’t know the exact circumstances of the collision?
