Understanding Circular Motion and Angular Velocity

What is the angular distance covered in one complete revolution of a circle?

• 180 degrees

• 2 pi radians

• pi radians

• 360 degrees

How many revolutions per second is an object making if it completes 10 pi radians per second?

• 5 revolutions per second

• 10 revolutions per second

• 2 revolutions per second

• 20 revolutions per second

What does angular velocity measure?

• The rate of change of an angle

• The speed of an object

• The time taken for one revolution

• The distance traveled by an object

In which direction does the angular velocity vector point when an object spins counterclockwise?

• Into the page

• Out of the page

• To the left

• To the right

What rule helps determine the direction of the angular velocity vector?

• Thumb rule

• Index rule

• Right-hand rule

• Left-hand rule

How is angular velocity typically treated in a two-dimensional plane?

• As a scalar quantity

• As a vector quantity

• As a pseudo-vector

• As a pseudo-scalar

What is the formula for speed in terms of angular velocity and radius?

• Speed = radius / angular velocity

• Speed = angular velocity * radius

• Speed = radius * angular velocity

• Speed = angular velocity / radius

If the angular velocity is omega and the radius is r, what is the speed of the object?

• r / omega

• omega / r

• omega * r

• r * omega

How can you solve for angular velocity if you know the speed and radius?

• Angular velocity = radius / speed

• Angular velocity = speed / radius

• Angular velocity = radius * speed

• Angular velocity = speed * radius

What is the SI unit for angular velocity?

• Degrees per second

• Revolutions per second

• Radians per second

• Meters per second
