How do you change the speed without changing the angular momentum?
To change the speed without changing the angular momentum, you can change the radius of the rotating object. This is because angular momentum is the product of an object's moment of inertia, its mass, and its angular velocity. By adjusting the radius while keeping the other factors constant, you can alter the speed without affecting the angular momentum.
What is the angular momentum of the 2.6 kg 5.6 cm diameter rotating disk.?
Without knowing the angular speed, i.e. RPM or some such velocity, it is not possible to answer the question. Please restate the question, giving all of the required information.
How mass affects both angular and linear momentum?
Increasing mass affects both angular and linear momentum differently. For linear momentum, doubling the mass doubles the momentum if velocity remains constant. For angular momentum, increasing mass without changing the distribution around the axis of rotation affects angular momentum due to rotational inertia. In simple terms, the rotational speed would likely decrease to conserve angular momentum.
Is it possible to change translational kinetic energy of an object without changing it rotational energy?
Yes, it is possible to change the translational kinetic energy of an object without changing its rotational energy. Translational kinetic energy depends on an object's linear velocity, while rotational energy depends on its angular velocity. By adjusting the linear velocity without changing the angular velocity, you can change the object's translational kinetic energy without affecting its rotational energy.
Why is angular momentum NOT measured in kg m2 rad s-1?
For the same reason it's not measured in buckets of rotten fish: because those would not be the correct units. Angular momentum is the cross product of the linear momentum and the position vector relative to the center of rotation. If you do a dimensional analysis, you'll see that the proper units are joule-seconds.
Find the momentum of a 70kg runner?
The momentum of a 70kg runner can be calculated by multiplying the mass of the runner (70kg) by the velocity of the runner. Without the velocity, we cannot determine the momentum.
What is the momentum of a 20 kg object?
The momentum of an object is calculated as the product of its mass and velocity. Without knowing the velocity of the 20 kg object, the momentum cannot be determined.
If you have increased the momentum of a moving object without increasing its inertia then you have?
Increased its velocity. By not changing its mass (inertia) and increasing its momentum, the only variable left to change is velocity in the equation momentum = mass x velocity.
If the momentum of an object changes and its mass stays the same what happens?
If the momentum of an object changes while its mass remains constant, then its velocity must have changed accordingly. This relationship is described by the equation momentum = mass x velocity. So, if momentum changes without a change in mass, then velocity must have changed.
Why do you need momentum with kinetic energy?
Momentum is the product of mass and velocity. Kinetic Energy is the product of mass and velocity squared. As you can see, since Kinetic Energy is derived from mass and velocity, and Momentum is derived from mass and velocity, you cannot have one without the other.
How much momentum does a 500 kilograms mass have if its not moving?
"Momentum" is the product of mass x velocity. You can base your calculations on that.
How do the mass and velocity of a moving object affects its momentum?
As the velocity decreases, the momentum increases. Mass is the matter inside of something and momentum is how hard it is to stop something. Therefore momentum needs mass to function because without mass there would be no momentum. So think of the sentence above like this: velocity ( a measure of momentum) decreases, the momentum (including mass inside an object) goes up therefore making the mass increase while the velocity decreases.
