Answer 2

Answer:

Equation of motion can be used for only a straight line of motion. Thus the right answer is an option(a): a straight line of motion only.

Explanation:

• There are three equations of motion.
• The 1st equation is:

                                 $v=u +at$

• The 2nd equation is:

                                 $s=ut+\frac{1}{2} at^{2}$

• The 3rd equation is:

                                $v^{2}=u^{2}+2as$

where,

v = final velocity

u = initial velocity

a = acceleration

s = distance

• The condition to apply these 3 equations is that these equations will only be applicable to uniform accelerated motion on straight lines only.

So. the equation of motions is only used in the case of straight-line motion.
