Inertial Systems in Different Cases

An inertial system is a reference frame in which Newton's laws of motion hold true without any external forces acting on the system. Let's analyze each case to determine whether the system will be inertial:

A. The car is moving uniformly and in a straight line on a horizontal road: In this case, the car is not experiencing any acceleration or external forces. Therefore, the system can be considered inertial. B. The car is accelerating and moving in a straight line on a horizontal road: When the car accelerates, there is a net force acting on it. Therefore, the system is not inertial. C. The car is moving uniformly while ascending a hill: When the car moves uphill, it experiences a gravitational force opposing its motion. This force acts as an external force, making the system non-inertial. D. The car is accelerating while descending a hill: When the car accelerates downhill, it experiences a gravitational force aiding its motion. Although there is an external force acting on the car, it is not the cause of the acceleration. Therefore, the system can still be considered inertial. To summarize: - Cases A and D can be considered inertial systems. - Cases B and C are not inertial systems.
