Problem 8DQ

Some people say that the “force of inertia” (or “force of momentum”) throws the passengers forward when a car brakes sharply. What is wrong with this explanation?

Step-by-Step Solution:
Step 1 of 3

Solution 8DQ The passengers forward when a car brakes sharply.because of inertia of motion you feel the force in forward direction,your upper body tries to be in motion.hence inertia is the property by the virtue of which the body tries remains in state of motion. The wrong thing is not the force of inertia or force of momentum will throws the passengers forward when a car brakes sharply.it is inertia of motion that throws the passenger forward when a car brakes sharply. Or The explanation is not wrong.i would say it is right.in an accelerated frame of reference,not real inertial forces will appear,such as the centrifugal force.the force that throws you forward when a car breaks sharply is of the same character. Phenomenon in question is exclusively due to the non-inertial nature of the frame,which is equal to good explanation in inertial frame,the passenger just keeps traveling at constant velocity.
