Why does stopping a vehicle you’re in cause you to jerk forward, even though motion is supposed to be relative (and the vehicle isn’t moving from your “physics” perspective)?
In: Physics
The car and everything in it is all travelling at the same velocity when it is in normal motion, however when the brakes are applied they are only working to stop the velocity of the car, the brakes don’t stop the velocity of the passengers so you “jerk forward” until the seatbelt or something else stops you.
