Tutorial: Angular Momentum and Torque III. Angular Momentum The angular momentum of a point particle is defined by: L = ixp. Here, is a vector that points from the point of rotation (or point around which the angular momentum is calculated) to the location of the particle and p = mb is the linear momentum of the particle. A Your little brother Joey is playing with his toy airplane. The airplane is tied to a string and its motor makes...
I. Show that the angular momentum of a two-particle system is given by where m- mi + m2. v is the relative velocity (the velocity of one of the particles with respect to the other), is the relative position, and μ is the reduced mass. Q7- CM
Learning Goal: To learn the definition andapplications of angular momentum including its relationship totorque. By now, you should be familiar with the concept ofmomentum, defined as the product of an object's mass andits velocity: . You may have noticed that nearly every translationalconcept or equation seems to have an analogous rotationalone. So, what might be the rotational analogue of momentum? Just as the rotational analogue of force , called thetorque , isdefined by the formula , the rotational analogue of...
6. Angular Momentum and Torque on a Meteor A meteor enters Earth's atmosphere and is observed by someone on the ground before it burns up in the atmosphere. The vector 25 m i +25 m j gives the position of the meteor with respect to observer. At the instant the observer sees the meteor, it has linear momentum p 1.5 kg -2.0) m/s 3 and it is accelerating at a constant rate of 2.0 m/s(-3) along its path, which for...
A comet orbits the Sun and loses mass at a constant rate of
30,000kg/s. The only force acting on the comet is the gravitational
force.
a) From the definition of torque in terms of angular momentum,
torque=dL/dt, show that
dI/dt=-alphaI/omega (alpha= angular acceleration, omega=angular
velocity)
b) The quantity omega/omega(with a dot on it), where (omega with
a dot on it=domega/dt) is a natural time scale for the system's
change in angular frequency (to see this, think about the units).
Approximating...
what are the units for torque, moment of inertia, and angular acceleration? show all work. write out the equations with unit cancellation shown to show where we get the units for each ^ please!!
This is an interesting phenomenon, and a very difficult one to explain. Both torque and angular momentum must be treated as vectors. Torque causes angular momentum to change according to the following equation: delta L rightarrow = rightarrow delta T To use this equation the direction of a torque vector must be defined. Follow the moment arm with the fingers of your right hand. Then turn your fingers to follow the force. As you do this, your thumb will point...
