# How do I convert from radians/s/s to meters/s/s?

0

The number is 26.73 rad/s/s, do I multiply that by 2pi or divide, or something all together different to get meters/s/s?

• use a calculator

• To convert you would have to know the distance from the center – the travel radius. If the distance was 1 meter, then each radian would also be 1 meter.

• Fred, of course the object is travelling in a circle, otherwise it would not have such radial acceleration… also the asker would not want to convert from rad/s/s to m/s/s.

A point object travelling in circular motion can have either tangential acceleration in m/s/s or a constant tangential velocity in m/s

• radian / sec^2 is the unit for angular acceleration, while m/sec^2 is the unit for linear acceleration and if you want to convert these units mutually, you should use the relation

linear accelration a = radius r x angular accelration alpha

as such you have to know the radius of the circle.

• Radian is a measure of angular distance. Metre is a measure of linear distance. As they are conversion is not a reasonable thing to consider.

• radian is a measure of angles where meters is distance. they can’t be equated unless the object is travelling in a circle.

• 1 rotation = 2π radians = Circumference

Circumference = 2πr
