What physical principle explains conservation of motion in crashes?
Correct!
Wrong!
This principle helps calculate post-impact speeds.
What equation estimates speed from skid marks?
Correct!
Wrong!
The formula relates speed to distance and friction.
What does Newton’s Second Law state?
Correct!
Wrong!
This law links force with mass and acceleration.
Why is drag factor important?
Correct!
Wrong!
It affects speed calculations based on road surface.
What unit is acceleration typically measured in?
Correct!
Wrong!
Correct units ensure accurate calculations.
What role does mass play in crash energy?
Correct!
Wrong!
More mass results in greater impact energy.
