MP Board · Class 9 · Science · MotionWrite the first equation of motion and define all the terms involved in it.

The first equation of motion describes the relationship between final velocity, initial velocity, uniform acceleration, and time taken. The equation is written as: $$v = u + at$$\nIn this equation, the terms represent:

• $v$ = final velocity of the object (measured in $\text{m/s}$)
• $u$ = initial velocity of the object (measured in $\text{m/s}$)
• $a$ = uniform acceleration of the object (measured in $\text{m/s}^2$)
• $t$ = time taken for the velocity change (measured in seconds, $\text{s}$)\nThis equation is directly derived from the fundamental definition of acceleration.
