Calculating Angular Acceleration of a Pulsar

In summary, the conversation discusses tangential acceleration and its relation to pulsars. A pulsar is a rotating neutron star that emits radio pulses at precise time intervals. The period of rotation, T, is measured by the time intervals between pulses and is currently at 0.033 seconds. The period increases by 1.26 x 10-5 seconds per year. The question asks about the size of the angular acceleration, with hints provided about the units and radians in one revolution.

Hi everyone!

I have a question about tangential acceleration:

A pulsar is a rotating neutron star which sends out radio pulses with precise time intervals. Every time the star rotates a pulse is received. The period, T, is measured by measuring the time intervals between the pulses. Today the pulsar has a rotation period T = 0,033 s and the period increases with 1,26 x 10-5 s per year.

How big is the angular acceleration?

Thanks everyone for taking a look at this! :)

Related to Calculating Angular Acceleration of a Pulsar

1. What is angular acceleration?

Angular acceleration is a measure of how quickly an object's angular velocity changes. It is calculated by dividing the change in angular velocity by the change in time.

2. How is angular acceleration different from linear acceleration?

Angular acceleration is a measure of how quickly an object's angular velocity changes, while linear acceleration is a measure of how quickly an object's linear velocity changes. Angular acceleration is measured in radians per second squared, while linear acceleration is measured in meters per second squared.

3. What causes angular acceleration?

Angular acceleration is caused by a net torque acting on an object. This can be due to a force applied at a distance from the object's axis of rotation, or a change in the distribution of the object's mass.

4. How is angular acceleration related to angular velocity?

Angular acceleration is the rate of change of angular velocity. This means that the higher the angular acceleration, the faster the angular velocity will change.

5. How is angular acceleration measured?

Angular acceleration is typically measured using a device called an accelerometer, which senses changes in rotational motion. It can also be calculated by taking the second derivative of an object's angular displacement with respect to time.
