1. What is the SI unit for angular velocity?
meters per second (m/s)
radians per second (rad/s)
revolutions per minute (rpm)
degrees per second (°/s)
2. Which of the following best describes the direction of angular velocity?
Tangent to the circular path
Towards the center of the circle
Perpendicular to the plane of rotation, following the right-hand rule
Opposite to the direction of linear velocity
1. Angular velocity is the rate of change of displacement.
2. The relationship between linear velocity (v), angular velocity (ω), and radius (r) is given by v = .
3. One complete revolution is equal to radians.
1. A car tire rotates at 500 revolutions per minute. Calculate its angular velocity in radians per second.
2. A point on the edge of a spinning disk is 0.25 meters from the center. If the disk has an angular velocity of 10 rad/s, what is the linear velocity of that point?
3. Explain the difference between angular speed and angular velocity.
1. Angular velocity is a scalar quantity.
