Question

1) 2 Laws of motion are valid in a frame of referer (A) Inertial (B) non-inertial at rest C (D) none of the above​

Answer 1

Answer:

Natural forces like tension, normal force are same from all inertial frame.

There are two types of frame of reference

1). INERTIAL FRAME OF REFERENCE- that reference which remains at rest or moves with constant speed is called inertial frame.

Newton’s law of motion is valid in this frame of reference.

2). NON INERTIAL FRAME OF REFERENCE- when the body is accelerated without being acted upon by external force then it is called non- inertial frame.

Newton’s laws are not valid in this frame.

The acceleration of the body in non inertial frame of reference is different from that of inertial frame as supplementary force like pseudo forces are taken into account.

Sun is the center of mass of the solar system and is considered as inertial frame of reference except it motion is slow like non inertial frames but we can't conduct any experiment to find its reference frame.

Answer 2

Answer:

There are two types of frame of reference

1). INERTIAL FRAME OF REFERENCE- that reference which remains at rest or moves with constant speed is called inertial frame.

Newton’s law of motion is valid in this frame of reference.

2). NON INERTIAL FRAME OF REFERENCE- when the body is accelerated ithout being acted upon by external force then it is called non- inertial frame.

Newton’s laws are not valid in this frame.

The acceleration of the body in non inertial frame of reference is different from that of inertial frame as supplementary force like pseudo forces are taken into account.
