## What happens when tangential acceleration is constant?

In the case of the uniform circular motion, the speed (v) of the particle in uniform circular motion is constant (by definition). This implies that tangential acceleration, aT, is zero.

## Does constant speed mean no tangential acceleration?

What you’re talking about is constant speed, which is the absolute value of the velocity. Also, no it is not possible. If the acceleration is tangent to the velocity, it would just accelerating or breaking linearly, so a circular movement would not even be possible.

**How do you solve for tangential acceleration?**

The tangential acceleration = radius of the rotation * its angular acceleration. It is always measured in radian per second square. Its dimensional formula is [T-2].

**How do you find the constant tangential speed?**

Divide the circumference by the amount of time it takes to complete one rotation to find the tangential speed. For example, if it takes 12 seconds to complete one rotation, divide 18.84 by 12 to find the tangential velocity equals 1.57 feet per second.

### Is tangential acceleration always zero?

Tangential acceleration results from the change in magnitude of the tangential velocity of an object. An object can move in a circle and not have any tangential acceleration. No tangential acceleration simply means the angular acceleration of the object is zero and the object is moving with a constant angular velocity.

### Can you go around a curve with constant acceleration?

Can you go around a curve with constant acceleration? No, because the vector always points to the center of the circle and you are always changing the direction of that vector.

**What is the tangential component of acceleration?**

The tangential acceleration is a measure of the rate of change in the magnitude of the velocity vector, i.e. speed, and the normal acceleration are a measure of the rate of change of the direction of the velocity vector.

**Is linear acceleration the same as tangential acceleration?**

In the context of circular motion, linear acceleration is also called tangential acceleration at. Linear or tangential acceleration refers to changes in the magnitude of velocity but not its direction.

#### Why is centripetal acceleration not constant?

Even if the speed of the particle is constant, the particle has some acceleration just because the direction of its velocity is continually changing. What’s more, the centripetal acceleration is not a constant acceleration because its direction is continually changing.

#### Why there is no tangential acceleration?

Why is there no tangential acceleration in uniform circular motion? Because, then we wouldn’t call it uniform. Circular motion can have both tangential a∥ and centripetal a⊥ acceleration. They are then the components of an acceleration vector →a=(a∥,a⊥) pointing at an angle.
