The Tangential Acceleration Calculator serves as a fundamental tool to determine the rate of change in an object’s velocity as it moves along a circular path. This tool proves beneficial in physics and engineering, aiding in the calculation of tangential acceleration based on the radius of the circular path and angular acceleration.
Formula of Tangential Acceleration Calculator
The formula for tangential acceleration (aₜ) is given by:
aₜ = r * α
Where:
- “aₜ” represents the tangential acceleration measured in meters per second squared (m/s²).
- “r” denotes the radius of the circular path, measured in meters (m).
- “α” signifies the angular acceleration measured in radians per second squared (rad/s²).
Angular acceleration (“α”) represents the rate at which an object’s angular velocity changes. If the initial angular velocity (“ωᵢ”), final angular velocity (“ωₕ”), and the time interval (“t”) are known, the angular acceleration can be calculated using the formula:
α = (ωₕ – ωᵢ) / t
Where:
- “α” denotes the angular acceleration measured in radians per second squared (rad/s²).
- “ωₕ” represents the final angular velocity measured in radians per second (rad/s).
- “ωᵢ” represents the initial angular velocity measured in radians per second (rad/s).
- “t” represents the time interval over which the change in angular velocity occurs, measured in seconds (s).

Example of Tangential Acceleration Calculator
Suppose an object moves along a circular path with a radius of 2 meters and experiences an angular acceleration of 4 radians per second squared.
Using the formula aₜ = r * α, we can calculate the tangential acceleration:
aₜ = 2 * 4 = 8 m/s²
Most Common FAQs
A: Tangential acceleration represents the rate of change in velocity along the circular path, whereas centripetal acceleration is directed towards the center and keeps an object in circular motion.
A: Yes, angular acceleration can be negative, indicating a decrease in angular velocity over time.
A: If the radius is zero, the tangential acceleration would also be zero, as there would be no circular motion.
