Question

Which of the following equations does not represent the kinematic equations of motion?

• A. $\mathrm { v } = \mathrm { u } + \mathrm { at }$
• B. $\mathrm { S } = \mathrm { ut } + \frac { 1 } { 2 } \mathrm { at } ^ { 2 }$
• C. $\mathrm { S } = \mathrm { vt } + \frac { 1 } { 2 } \mathrm { at } ^ { 2 }$
• D. $v ^ { 2 } - u ^ { 2 } = 2 a S$ where, u = initial velocity of a body v = final velocity of the body a = uniform acceleration of the body S = distance travelled by the body in time t

Answer 1

Answer: (C)

$\mathrm { S } = \mathrm { vt } + \frac { 1 } { 2 } \mathrm { at } ^ { 2 }$

Answer 2

$S = v t + \frac { 1 } { 2 } a t ^ { 2 }$

It is a not a kinematic equations of motions.

All other are three kinematic equations of motions.
