How do crumple zones, seat belts, and airbags protect passengers during a collision?

Back

They decrease the force on people during a collision by increasing the time for the people to stop.

Front

What is the formula for gravitational force?

Back

The gravitational force is calculated using the formula F = G * (m1 * m2) / r^2, where G is the gravitational constant, m1 and m2 are the masses of the objects, and r is the distance between their centers.

How do seat belts function to protect passengers?

Back

Seat belts restrain passengers and distribute the force of a collision over a larger area of the body, reducing injury.
