What law of inertia happens when the bus suddenly stops?
What law of inertia happens when the bus suddenly stops? And the bus stopped suddenly. I fell down. Because of Newton's Law of Inertia, which states: An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
Is a moving bus suddenly stops is its momentum destroyed?
The energy of the bus has to go somewhere, and the momentum too, as they are independently conserved. Part of the energy goes to heat, in the brakes and on the contact ground/wheels. Heat means photons, so photons may take away some momentum. But most momentum through friction is transferred to the ground .
