Read each question carefully and answer to the best of your ability. Show all your work for calculation problems.
1. Which of the following best describes angular velocity?
The speed at which an object moves in a straight line.
The rate at which an object changes its position along a circular path.
The rate at which an object rotates or revolves relative to another point.
The total distance covered by an object in circular motion.
2. If a point on a rotating disk has a constant angular velocity, what can be said about its linear velocity?
It is also constant.
It is constantly changing direction.
It is zero.
It is always increasing.
3. Angular velocity is typically measured in units of .
4. The relationship between linear velocity (v), angular velocity (ω), and the radius (r) of circular motion is given by the formula: v = .
5. For an object moving in a circle, all points on the object have the same linear velocity.
True
False
6. A larger radius will result in a greater linear velocity for the same angular velocity.
True
False
7. A bicycle wheel has a radius of 0.35 meters and rotates at an angular velocity of 12 radians per second. Calculate the linear velocity of a point on the edge of the wheel.
8. Explain the difference between angular velocity and linear velocity in your own words, providing an example of each.
9. Observe the gears below. If the larger gear rotates at a certain angular velocity, how would the angular velocity of the smaller gear compare? Explain your reasoning.
