Inertial and Non-Inertial Frames of Reference

A reference frame attached to the earth

In a non-inertial frame the second law of motion is written as

A bock is sliding along smooth incline as shown in figure. If the acceleration of chamber is a as shown in the figure. The time required to cover a distance
$L$ along the incline is:

The weight of a body is $5 \mathrm{kgwt}$or$5 \mathrm{kgf}$ when placed at rest, if it is now placed in a lift (a) moving up with acceleration $4.9 \mathrm{m} {\mathrm{s}}^{-2}$ (b) moving down with acceleration $4.9 \mathrm{m} {\mathrm{s}}^{-2}$ (c) moving down with acceleration $9.8 \mathrm{m} {\mathrm{s}}^{-2}$ then what will be the weight of that body in absolute S.I. units for all the cases?

A block of mass $1 \mathrm{kg}$ is placed on a rough wedge which is fixed on an elevator moving upward with constant velocity $2 \mathrm{m} {\mathrm{s}}^{-1}$. The block is at rest w.r.t. wedge. Net reaction force on the block is $\left(\mathrm{g}=10 \mathrm{m} {\mathrm{s}}^{-2}\right)$

The resultant force acting on a moving body is zero, then

If $m$ does not slide on wedge, find reading of weighing machine

Figure shows two identical blocks of mass $\mathrm{m}$ kept on a smooth floor. Block $A$ is connected to front wall with a just straight string and block $B$ is connected to rear wall with a relaxed spring. Assume that the floor of the train car is smooth and exerts no horizontal forces on the block. Mark the correct statement (s). Initially train is moving with constant speed.

What is Coriolis force?

Give an example of a body which is at rest with respect to one body, but is in motion with respect to another.

On the basis of frame of reference in how many types is the motion divided?

What is a frame of reference?

In which of the following cases does Newton's second law is not applicable?

Newton's laws are not applicable when

(1) Observation is done via inertial frame of reference
(2) Observation is done via non-inertial frame of reference
(3) Object is travelling with a speed comparable to the speed of light

What was the limitations of Newton's law

Newton’s first law of motion is not valid for______

Newton's laws of motion cannot be applicable to the particle moving at a speed comparable to the speed of

Are there limitations to Newton’s third law? Why?

Give two examples of non-inertial frame of reference.
