We learned about Pressure to explain which safety feature?

• Airbags

• Crumple zone

When calculating Work (W = F x d), Force and Distance are ___________________.

• Inversely Proportional

• Directly Proportional

• Evenly Proportional

• Not related

The Physics concepts we learned when we talked about airbags were:

• Speed and Velocity (d/t)

• Work (F*d) and Impulse (F*t)

• Acceleration (v/t) and Area (L*W)
