Query regarding to the frame of reference

In summary, a frame of reference is a set of coordinates used to measure and describe the position, motion, and orientation of objects in space. It is important to establish a frame of reference in order to understand the physical world and make accurate measurements. A frame of reference is determined by selecting a point of origin and axes of measurement. There can be multiple frames of reference for the same scenario, and each frame may yield different measurements and descriptions of motion. A frame of reference is relative, but there are also absolute frames of reference that are used for more precise measurements and calculations.

If a metallic ball is place inside a giant hollow top, and the top starts to rotate. Along with the top, the metallic ball will also start to rotate. Thus my question is the ball motion is under inertial frame of reference or non-inertial ?

If the metallic ball is rotating, a frame of reference where the ball is not moving is non-intertial.

Means is the ball under non-inertial frame of reference?

The ball is under constant acceleration, therefor it is in a non-inertial frame of reference.

The motion of the metallic ball in this scenario can be considered under both an inertial and non-inertial frame of reference. Initially, the ball is at rest and in a state of equilibrium inside the hollow top, which can be considered an inertial frame of reference. However, once the top starts to rotate, the ball will experience a centrifugal force that causes it to move in a circular path along with the top. This circular motion can be considered as a non-inertial frame of reference. Ultimately, the motion of the ball can be described using both frames of reference, depending on the specific parameters and variables being considered.
 

1. What is a frame of reference?

A frame of reference is a set of coordinates used to measure and describe the position, motion, and orientation of objects in space. It serves as a point of reference for determining the location and movement of objects relative to each other.

2. Why is it important to establish a frame of reference?

Establishing a frame of reference is crucial in understanding the physical world and making accurate measurements. It allows for consistent and standardized descriptions of motion and position, and helps to eliminate confusion and errors when communicating about objects in motion.

3. How is a frame of reference determined?

A frame of reference is typically determined by selecting a point of origin and axes of measurement. The point of origin is a fixed reference point from which all other positions are measured, while the axes define the directions in which measurements are made.

4. Can there be multiple frames of reference?

Yes, there can be multiple frames of reference for the same scenario. Each frame of reference may yield different measurements and descriptions of motion and position, but all are valid and can be used to understand and analyze a system.

5. Is a frame of reference relative or absolute?

A frame of reference is relative, meaning it is dependent on the observer's viewpoint. Different observers may have different frames of reference, and each frame will be equally valid for their own observations. However, there are also absolute frames of reference, such as the fixed stars in space, that are used for more precise measurements and calculations.
