Formula Used
Where:
Fₜ = Tangential Force (N)
m = Mass (kg)
r = Radius (m)
α = Angular Acceleration (rad/s²)
Alternatively, if torque (τ) is provided: Fₜ = τ / r
Frequently Asked Questions
Tangential force is the force acting along the tangent to the circular path of a rotating object. It’s responsible for changing the magnitude of the object’s velocity (speed) but not its direction in circular motion.
Centripetal force acts radially inward and is responsible for changing the direction of velocity (keeping the object in circular motion), while tangential force acts along the tangent and changes the magnitude of velocity (speeding up or slowing down the rotation).
Yes, if you know the torque (τ) applied and the radius (r), you can calculate tangential force using the formula Fₜ = τ / r. Our calculator supports both methods of calculation.
For accurate results, use these units:
- Mass: kilograms (kg)
- Radius: meters (m)
- Angular acceleration: radians per second squared (rad/s²)
- Torque: newton meters (Nm)
Tangential force calculations are essential in many engineering applications including:
- Design of rotating machinery (engines, turbines)
- Vehicle dynamics (wheel traction)
- Robotics (joint movements)
- Spacecraft attitude control
- Industrial conveyor systems
