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’s various parts also experience the forces from acceleration and deceleration. Just that it’s all bolted together so it’s much less likely to jostle around like you would, but you will notice that a car will look to be leaning forward on a hard stop or back on hard acceleration in relation to its wheels (which are also experiencing forces).
You and the vehicle are most definitely moving from the perspective of the Earth and gravity.
