What is angular acceleration?
Angular acceleration is the trate of change of angular velocity, often represented by the letter alpha.
How do you find out the direction of angular accelaration?
The direction of angular acceleration comes from whether the angular speed of the object is clockwise or counterclockwise and whether it is speeding up or slowing down.The direction of the angular acceleration will be positive if the angular velocity is counterclockwise and the object's rotation is speeding up or if the angular velocity is clockwise and the object's rotation is slowing downThe direction of the angular acceleration will be negative if the angular velocity is clockwise and the object's rotation is speeding up or if the angular velocity is counterclockwise and the object's rotation is slowing downThe angular acceleration will not have a direction if the object's angular velocity is constant
How is the radius of rotation related to the centripetal force and angular velocity?
Assuming that angles are measured in radians, and angular velocity in radians per second (this simplifies formulae): Radius of rotation is unrelated to angular velocity. Linear velocity = angular velocity x radius Centripetal acceleration = velocity squared / radius Centripetal acceleration = (angular velocity) squared x radius Centripetal force = mass x acceleration = mass x (angular velocity) squared x radius
What is the difference between uniform and variable velocity?
Uniform velocity is velocity unaffected by acceleration. Variable velocity is velocity affected by acceleration. Lauren "Physics above all!"
When a cars velocity is uniform what it is acceleration?
Acceleration is change of velocity divided by time; so if the velocity doesn't change, acceleration is zero.
What is angular acceleration?
Angular acceleration is the trate of change of angular velocity, often represented by the letter alpha.
When angular velocity decreases the direction of angular acceleration is opposite to angular velocity .why?
Take the velocity to be in positive direction. Positive acceleration increases velocity and they are in the same direction. Negative acceleration reduce velocity and they are in opposite direction. It does not matter if the motion in linear or anfular.

Is angular momentum always parallel to angular acceleration?
momentum is product of moment of inertia and angular velocity. There is always a 90 degree phase difference between velocity and acceleration vector in circular motion therefore angular momentum and acceleration can never be parallel

Why is acceleration zero with uniform velocity?
Uniform velocity means the velocity is not changing. Acceleration is defined as the rate of change of velocity. If velocity isn't changing, the rate of change is zero.
How do you find the uniform acceleration if the speed and acceleration are given?
Find out the time using speed and acceleration, (time=speed/acceleration) and then use it to find out uniform velocity. From that find out uniform acceleration. (as uniform acceleration is equal changes of velocity over equal intervals of time)
What is the importance of uniform acceleration graph in physics what is instantaneous velocity?
The slope of a velocity-time graph that shows uniform acceleration is the actual acceleration. Instantaneous velocity is the velocity of a body at a particular moment in time.
When a cars velocity is uniform what it is acceleration?
Acceleration is change of velocity divided by time; so if the velocity doesn't change, acceleration is zero.
Why is the body moving with a uniform velocity is zero?
The body is not zero, but the sum of all forces on it is. -- "Uniform velocity" means no acceleration. -- Acceleration is force/mass . -- If acceleration is zero, that's an indication that force must be zero.
How many times centripetal force will increase if the angular speed of a body moving with uniform speed moving in a circle is increases?
Centripetal acceleration, and therefore centripetal force, is proportional to the square of the angular velocity. For example, if you increase the angular velocity by a factor of 10, the centripetal force will be increased by a factor of 100.
