How does Newton's second law apply to a car crash?

Answer 1

The force of a crash increases when either the mass or the acceleration increases.

Newton's second law, #F=ma#, states that the force of something is directly proportional to both the mass and the acceleration of a moving object.

This implies that an increase in either of these two variables will result in an increase in the total force applied to the object in question. For example, if a car weighing 2000 kg accelerates to 60 mph, the net force generated during a collision will be higher than the net force generated when a car with the same mass and speed crashes at 30 mph.

In a car crash, Newton's second law states that the force experienced by the occupants of the car is directly proportional to the rate of change of momentum, which is the product of mass and velocity. This means that the greater the mass of the car or the higher its velocity before the crash, the greater the force experienced by the occupants during the collision.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
