# The angular velocity vector of earths rotation points from?

Without looking it up, I'll go out on a limb here and state my guess. (Then somebody else can come along and show that my guess was all wet.) I think angular velocity and acc… Continue reading

# At what angular velocity would the earth have to rotate about its axis for a body at the equator to feel no weight?

You can calculate it yourself, with the formula for acceleration in uniform circular motion. The centripetal acceleration, with circular motion, is v2 / r (velocity squared di… Continue reading

# What the relationship between angular velocity and period of rotation?

  The time, T , it takes for an object to go thru one comblete rotation of 360 degrees or 2pi radians is its "period". The rate at which it completes the rotation is its "… Continue reading

# Is angular speed the same as angular acceleration?

No. Acceleration and speed are related in the same way irrespective of being linear or angular. Acceleration is rate of change of speed.

Thanks for the feedback!

# What is angular speed and angular velocity?

That is analogous to linear speed and velocity, but for rotation. Whereas a linear speed (or velocity) is expressed in meters per second (or some other units of distance / tim… Continue reading

# What is angular velocity and radial velocity?

Angular velocity is the rate of change of angle of a body, i.e. omega = v / r = (2*pi*r)/ r*t = (2*pi)/ Twhere T is the time period of whatever is rotating and r is the radi… Continue reading
