What else can I help you with?
What does not have the same units as the others Kinetic Energy Momentum Potential Energy or Work?
Momentum does not have the same units as the others. Kinetic energy is measured in joules, potential energy in joules, work in joules, but momentum is measured in kilogram meters per second (kg m/s).
Are momentum and impulse measured in the same units?
No, momentum is measured in units of kilograms times meters per second (kgm/s), while impulse is measured in units of Newton seconds (Ns). Momentum is a measure of an object's motion, while impulse is a measure of the change in momentum experienced by an object.
What are compatible observable in quantum mechanics?
Two operators that are also observables, which means that they correspond to some physically measurable quantity. Compatible observables are two or more such operators that can be measured at the same time. Position and momentum are an example of Incompatible observables, since one can only know either the position or the momentum of an object to 100% accuracy.
In 1927 who proposed that the position and momentum of a moving object cannot simultaneously be measured and known exactly?
Werner Heisenberg, a German physicist, proposed the Uncertainty Principle in 1927, which states that it is impossible to know both the exact position and momentum of a particle at the same time. This principle fundamentally changed the way we understand the behavior of particles at the quantum level.
Which has more momentum heavy truck light truck or do they both have the same momentum?
A truck that is more massive with the same velocity as the truck that is less massive will definitely have more momentum. This is illustrated in the equation for momentum:p = mvWhere p is momentum which is measured in Newton seconds, m is mass which is measured in kilograms, and v is velocity, measured in meters per second. If you plug in a larger mass for that same equivalent velocity, it will accordingly have more momentum.Also, if you just think about it, what would be harder to move: something with more mass or something with less mass?
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.
According to the heisenberg uncertainty principle if the position of a moving particle is known what other cannot be known?
According to the Heisenberg uncertainty principle if the position of a moving particle is known velocity is the other quantity that cannot be known. Heisenberg uncertainty principle states that the impossibility of knowing both velocity and position of a moving particle at the same time.
Why is it incorrect to say that impulse equals momentum?
Impulse is the change in momentum. Therefore Impulse is only equal to momentum if the initial momentum was equal to zero. Its the same phenomenon as position and displacement. Impulse= final momentum-initial momentum= mv - mv_0= Force * Time Where m is the mass and v is the velocity.
Do electrons travel so fast that it is impossible to know their exact location?
No, that's not how it works. The Heisenberg Uncertainty Principle states that there is a limit to how precisely you can measure position and momentum simultaneously. Actually, it's not just about measuring, position and momentum are not DEFINED at the same time, with arbitrary precision.An electron can very well move slowly, but the Uncertainty Principle still applies.
When can a car and truck have the same momentum?
Momentum is the product of mass x velocity, so if this product is the same for both, they will have the same momentum.
2 objects with same velocity have same momentum if they have the same?
mass. Momentum is the product of an object's mass and its velocity, so if two objects have the same velocity and mass, then their momentum will be the same.
Is the direction of angular velocity same as that of angular momentum when agular velocity is decreasing?
Yes, suppose a body is rotating anti-clockwise, then its angular velocity and angular momentum, at any moment are along axis of rotation in upward direction. And when body is rotating clockwise, its angular velocity and angular momentum are along axis of rotation in downward direction. This is regardless of the fact whether angular velocity of the body is increasing or decreasing.
