Homework Statement
How can i define a perfectly inertial frame ?
An inertial frame is a reference frame in which Newton's laws of motion hold true. This means that an object at rest will remain at rest, and an object in motion will continue to move at a constant velocity unless acted upon by an external force.
In an inertial frame, perfection can be defined as the absence of external forces acting on an object. This means that the object will move with constant velocity in a straight line, without any acceleration or deviation from its path.
An inertial frame is important in science because it provides a consistent and reliable reference point for studying the motion of objects. By eliminating external forces, scientists can better understand the fundamental principles of motion and accurately predict the behavior of objects.
An inertial frame is a reference frame where Newton's laws of motion hold true, while a non-inertial frame is a reference frame that is accelerating or rotating. In a non-inertial frame, objects may appear to experience forces even when no external forces are present, due to the frame's acceleration or rotation.
In theory, an inertial frame can exist in reality, but in practice, it is difficult to achieve. This is because there are always external forces acting on objects, such as gravity and friction, which can cause deviations from a pure inertial frame. However, for many scientific studies, it is possible to approximate an inertial frame with a high degree of accuracy.
