The car crash in which the car is moving at higher speed will cause catastrophic injuries whereas the car moving at smaller speed will cause minor injuries. This is due to the law of inertia of the bodies.
Explanation:
The inertia of a body is defined as the resistance of the body towards any change in its current state of rest or motion. The body does not want to change its state and this resistance of the body is directly proportional to the mass of the body.
According to the law of inertia, a body continues to be in its state of rest or motion until and unless an external force acts on the body.
A car moving at a higher speed and having a higher mass is considered to have higher inertia of motion and therefore when it crashes, it experiences a very high stopping force and due to this, the injuries caused in the car crash will be very catastrophic.
Whereas, if the same car is moving at a lower speed, the inertia of motion of the car will be less and when this car crashes, it will experience a smaller force and comes to rest. Due to this, the injuries caused in the crash will be minor.
Thus, The car crash in which the car is moving at higher speed will cause catastrophic injuries whereas the car moving at smaller speed will cause minor injuries. This is due to the law of inertia of the bodies.
