2. Which of the following best describes angular momentum?
The tendency of an object to resist changes in its linear motion.
The product of an object's mass and velocity.
The rotational equivalent of linear momentum.
The force that causes an object to move in a straight line.
3. Torque is the rotational equivalent of .
4. The principle of conservation of angular momentum states that if no external acts on a system, the total angular momentum remains constant.
5. A larger lever arm will result in a smaller torque for the same applied force.
True
False
6. An ice skater spins faster when she pulls her arms inward due to the conservation of angular momentum.
True
False
7. A force of 50 N is applied to a wrench at a distance of 0.25 m from the bolt. Calculate the torque produced.
8. Explain the difference between torque and force.
9. Consider the lever shown below. If a force of 100 N is applied at point A, what is the torque about the pivot point P?
(Assume the distance from A to P is 0.5 meters)
