What can we explain about how we can use physics to reduce driving risk?

How does speed affect whether or not you will avoid a collision?

OP_PM_L5_001.jpg

Is there also a quantitive relationship between the change in momentum, force, and the amount of time the force acts on an object?

​

OP_PM_L8_001.jpg

How do safety features affect the forces over time on a person during a collision?

​

OP_PM_L11_001.jpg

Should we make all vehicles bigger because that will also decrease the forces on the occupants in a collision?

OP_PM_L1_004_edited.jpg

Why is driving safer today than it was ten years ago, even though the number of vehicle collisions has gone up?

OP_PM_L4_001.jpg

How does the speed (and the mass) of the vehicles in a collision affect the outcome?

OP_PM_L6_017_edited.jpg

Can our models be used to explain real world scenarios involving quick stopping times and vehicles of different masses?

How does the rigidity and length of the crumple zone influence the safety of the occupants during a collision?

OP_PM_L12_001.jpg

What can we do as drivers, passengers, and residents that could make driving safer for everyone in our community?
