Angular Momentum Conceptual Questions
Angular Momentum Conceptual Questions. Explain why centripetal acceleration changes the direction of velocity in circular motion but not its magnitude. A wheel is released from the top on an incline.
A meteor enters earth’s atmosphere ( (figure)) and is observed by someone on the ground before it burns up in the atmosphere. (b) how does this angular momentum compare with the angular momentum of the moon on its axis? At the instant the observer sees the meteor, it has linear momentum.
Angular Momentum And Torque On A Meteor.
Explain why centripetal acceleration changes the direction of velocity in circular motion but not its magnitude. Just like linear momentum, one way, shown in the first equation, is to multiply the moment of inertia, the rotational analog of mass, with the angular velocity. When you start the engine of your car with the transmission in neutral, you notice that the car rocks in the opposite sense of the engine’s rotation.
A Wheel Is Released From The Top On An Incline.
Help center detailed answers to any questions you might have. Which rolls down an inclined plane faster, a hollow cylinder or a solid sphere? When this person extends her arms.
Can A Round Object Released From Rest At The Top Of A Frictionless Incline Undergo Rolling Motion?
A cylindrical can of radius. By the end of this section, you will be able to: Again, this chapter covers many aspects of rotational statics and dynamics;
Analogies Exist Between Rotational And Translational Physical Quantities.
Torque, moment of inertia, & angular momentum 1. The star's angular momentum l remains constant, and its rotational kinetic energy has increased. L = i ω = (0.032) (4) = 0.128 kg m2/s.
The Angular Momentum Of A Spinning Object Can Be Found In Two Equivalent Ways.
Explain why centripetal acceleration changes the direction of velocity in circular motion but not its magnitude. I = (2/5) (2) (0.2)2 = (4/5) (0.04) = 0.032 kg m2. The other way is simply multiplying the linear momentum by the radius, as shown in the second equation.
