Acceleration refers to the rate at which an object s velocity changes over time. It is a fundamental concept in physics, particularly in kinematics. Acceleration can be positive (speeding up) or negative (slowing down). The unit of acceleration is meters per second squared (m/s²).
| Key Points | Description |
| Definition | Rate of change of velocity |
| Unit | m/s² |
| Types | Positive (speeding up), Negative (slowing down) |
| Formula | $ a = frac{Delta v}{Delta t} $ |
| Example | A car speeding up from 0 to 60 km/h in 10 seconds |
Understanding acceleration helps in analyzing motion and is crucial in fields like engineering and sports science.
