Pressure!
What is pressure?
How do you calculate pressure?
Force per area, where force is perpendicular to the surface.
P=F/AP=pressure (pascal)F=Force (Newtons)A=Area (m2)

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?
