Tangential Acceleration Calculator

Tangential acceleration tells us how fast an object speeds up along a circular path. It’s key in physics for wheels, planets, and anything that spins. With our Tangential Acceleration Calculator, you can calculate it in seconds without confusion.

You’ll learn how to use the calculator, the formulas behind it, and get step-by-step results.

What is Tangential Acceleration?

Tangential acceleration measures the change in speed along the edge of a circle. If something spins faster or slower, this acceleration changes. It’s different from centripetal acceleration, which pulls objects toward the center.

In simple words, tangential acceleration tells you how quickly an object’s speed along a circular path increases or decreases.

Formula for Tangential Acceleration

There are two common ways to calculate tangential acceleration:

1. Using Radius and Angular Acceleration

The formula is:

aₜ = r × α

Where:

• aₜ = tangential acceleration (meters per second squared)
• r = radius of the circle (meters)
• α = angular acceleration (radians per second squared)

Example: A wheel of 2 meters radius spins with an angular acceleration of 3 rad/s².

aₜ = 2 × 3 = 6 m/s²

2. Using Change in Velocity and Time

Another formula is:

aₜ = Δv / Δt

Where:

• Δv = change in velocity (m/s)
• Δt = change in time (seconds)

Example: A car’s wheel speeds up from 0 to 10 m/s in 2 seconds.

aₜ = 10 / 2 = 5 m/s²

Yes, this is exactly the same as “vf minus vi divided by t”.

How to Find Rotational Acceleration

Rotational acceleration is just another name for angular acceleration. Once you know α, you can find tangential acceleration by multiplying α with the radius.

If you know the speed change of a spinning object over time, use Δv / Δt.

FAQs

What is the formula for tangential acceleration?

aₜ = r × α or aₜ = Δv / Δt. Both are correct depending on the available data.

Is acceleration vf minus vi divided by t?

Yes. That’s the second formula for tangential acceleration.

How do I find rotational acceleration?

Rotational acceleration is the angular acceleration (α). Multiply it by the radius to get tangential acceleration.

Is tangential acceleration dv/dt?

Exactly. The rate of change of linear velocity along the tangent gives tangential acceleration.

Can I use this calculator for any spinning object?

Yes. Wheels, planets, turbines, or any circular motion works.
