4 cards from this section. Quick, good the night before a test.
Define angular momentum in your own words.
Think about how mass and speed relate to a spinning object.
What is torque and how is it related to angular momentum?
Remember the right-hand rule for direction.
What does the angular momentum depend upon?
Think about the formula L = mvr.
True or False: Body forces can be considered as forces acting at a point.
Remember how forces like gravity act on an entire body.
A solid cube experiences a uniform gravitational field. If we define the cube's mass as 4 kg and its side length as 2 m, calculate the torque about an axis through one corner due to the weight of the cube.
Use the torque equation while considering the right geometry of the cube.
A cylinder is rotating with an angular velocity of 5 rad/s. It is subjected to a constant torque of 10 Nm. Calculate the change in angular momentum after 4 seconds.
Remember that angular momentum is affected by the net torque applied over time.
