For the study of any kind of motion, we never use Newton’s first law of motion directly. Why should it be studied?

Correct Answer - D `vec(F)_(1)+t=0` `(5-t)hat(i)+[t^(2)-50+t^(2)]hat(j)=0` t = 5

1. Limitation : Newton’s laws of motion cannot be applied for objects moving in non-inertial (accelerated) frame of reference. Alternative solution : For non-inertial (accelerated) frame of reference, pseudo force needs to...

1. Newton’s first law shows an equivalence between the ‘state of rest’ and ‘state of uniform motion along a straight line.’  2. Newton’s first law of motion defines force as a...

Statement: The rate of change of linear momentum of a rigid body is directly proportional to the applied (external unbalanced) force and takes place in the direction of force. \(\overset\rightarrow{F}=\frac{d\overset\rightarrow{p}}{dt}\) Where, \(\overset\rightarrow{F}\) = Force...

Statement: To every action (force) there is always an equal and opposite reaction force).

1. Newton’s third law of motion defines action and reaction as a pair of equal and opposite forces acting along the same line. 2. Action and reaction forces always act on...

Forces of action and reaction always act on different bodies, hence they never cancel each other.

Correct option is: (C) 5.00 Given, F = 5N W = 9.80 a = ? W = mg \(9.80 = m \times 9.8\) m = 1 kg F = ma \(5 = 1 \times a\) \(a = 5 m/s^2\)

(D) it is applicable at all places of universe for all distances between all particles.
