What is the Difference Between Tangential Acceleration and Centripetal Acceleration?
🆚 Go to Comparative Table 🆚Tangential acceleration and centripetal acceleration are two components of the acceleration experienced by a particle or a rigid body in a circular motion. The main differences between them are:
- Direction: Tangential acceleration is always directed tangent to the circle, while centripetal acceleration is always directed inward, towards the center of the circle.
- Velocity: Tangential acceleration is the rate of change of tangential velocity, and it is normal to the radius vector. On the other hand, centripetal acceleration changes the direction of the velocity without affecting its magnitude.
- Vector Components: The net acceleration (a) can be obtained by the resultant of the two components, tangential acceleration (at) and centripetal acceleration (ac). For a particle in a circular motion, the acceleration vector always lies within the circular path.
To summarize:
- Tangential Acceleration:
- Directed tangent to the circle
- Changes the magnitude but not the direction of the velocity
- Expressed as at
- Centripetal Acceleration:
- Directed towards the center of the circle
- Changes the direction but not the magnitude of the velocity
- Expressed as ac

Comparative Table: Tangential Acceleration vs Centripetal Acceleration
Tangential acceleration and centripetal acceleration are both related to the motion of an object in a circular path, but they have distinct characteristics. Here is a table comparing the two:
Feature | Tangential Acceleration | Centripetal Acceleration |
---|---|---|
Definition | The rate of change of tangential velocity with respect to time. | The rate of change of angular velocity with respect to time. |
Direction | Tangential to the circular path. | Directed towards the center of the circular path. |
Velocity | Affects the magnitude of the tangential velocity. | Affects the direction of the tangential velocity. |
Geometric % | Much smaller than the centripetal acceleration. | Larger than the tangential acceleration. |
In summary, tangential acceleration is responsible for changes in the magnitude of the tangential velocity, while centripetal acceleration is responsible for changes in the direction of the tangential velocity. Both accelerations are essential for understanding the motion of objects in circular paths.
