1. Due to the laws of inertia if an object is stopped abruptly the
force of the moving object translates to whatever object it is in
contact with which will cause the person not wearing the seatbelt to be
propelled forward with the force of the car.
2. The stopping distance
changes if constant resistance is applied against two different forces
of varying magnitude such that the larger the force the greater the
stopping distance.
3. For the same Kinetic Energy the stopping
distance of a small vehicle will be less than the larger vehicle due to
the conversion of inertia.
4. The best way to prepare for sharp curves is to slow down the car before taking the curve.
5.
Due to the laws of inertia and conservation of momentum the faster the
car is moving the greater inertia that it will exert and the greater
momentum it will generate forward which if the car comes to a stop is
translated to the passengers inside which propels them forward with an
equivalent force which will be more pronounced as the object being
propelled by the same acceleration is now much smaller.
