Second Equation of Motion

Second Equation of Motion

### Formula:

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

### Terminologies:

- s → Displacement; change in position of an object.

- u → Initial velocity; velocity at the start of motion.

- t → Time interval; total time for which motion occurs.

- a → Acceleration; rate of change of velocity.

- t² → Square of time interval.

### Usage:

- Used to calculate displacement when initial velocity, acceleration, and time are known.
