Instantaneous Acceleration
### Formula:
$$a = \frac{dv}{dt}$$
### Terminologies:
- a → Instantaneous acceleration; acceleration at a particular instant.
- dv → Infinitesimal change in velocity.
- dt → Infinitesimal time interval.
- Derivative (d/dt) → Rate of change with respect to time.
### Usage:
- Used to calculate acceleration at a specific moment.
