How are cars safety features related to newtons 1st law
When there is an accident, the car stops, but your body is still in motion. Seatbelts, head rest, and airbags, prevent you from moving within the car
The greater the net force, the greater the objects
Acceleration will be
How do forces act
They act and pairs. These forces are equal in size and opposite indirection
