When a car stops suddenly and a passenger falls forward what law of motion is demonstrated?

The Law of Inertia states that an object in motion remains in motion and an object at rest remains at rest unless and unbalanced, outside force acts upon that object. Because the passengers are "attached" to the bus, they have the same inertia as the bus. But because the passengers are technically seperated, they have their own inertia. So when the bus is slowing down to a stop, the passengers inertia are to keep moving forward. As the bus moves back, the passengers want to keep moving forward. Which is why they lurch forward as the bus decelerates.


What is it called when a force is equal in strength but opposite in direction to an action force?

It is called a reaction force. The question you have asked is paraphrase of Newton's third law of motion. Action and reaction are always equal but opposite in direction.


What does newtons 2nd law state?

Newtons 2nd law means that when force is applied on any object an acceleration is produced in the direction of force which is applied on it. The acceleration produced in the object is directly proportional to the force applied on the object i.e. if force increases then acceleration will also increase and the acceleration is inversely proportional to the mass of object i.e. if the mass of the body decreases then acceleration will increase. If force is represented by 'F', acceleration by 'a' and mass by 'm' then a is directly proportional to F a is inversely proportional to m


Which law is Some energy is released as unusable heat energy into the environment?

This statement is based on the second law of thermodynamics, which states that in any energy transformation, some energy is lost as waste heat and cannot be converted back into usable energy. This principle underlies many natural processes and technological systems.


What is ferrels law?

Ferrel's law is the change in direction of prevaling winds when it comes to the equator. This deflection is caused by some random molecular motion due to the rise in temperature
