## Is the law of conservation of angular momentum?

The law of conservation of angular momentum states that when no external torque acts on an object, no change of angular momentum will occur.

## Who discovered angular velocity?

The components of the spin angular velocity pseudovector were first calculated by Leonhard Euler using his Euler angles and the use of an intermediate frame: One axis of the reference frame (the precession axis)

**Who first discovered momentum?**

At this point, we introduce some further concepts that will prove useful in describing motion. The first of these, momentum, was actually introduced by the French scientist and philosopher Descartes before Newton.

**Who discovered rotational motion?**

Aristarchus of Samos proved that the earth rotated on its axis in the third century BC. Eratosthenes correctly calculated the circumference of the earth to very high precision, and also correctly calculated the tilt of the earths axis. Then religion got in the way and all of that was forgotten for 1500 years.

### What is conservation of angular momentum BYJU’s?

The law of conservation of angular momentum states that, when the net external torque acting on a system is zero, its total angular momentum is conserved and hence, does not change.

### What is law of conservation of angular momentum give example?

Statement: The angular momentum of a body remains constant if the resultant external torque acting on the body is zero. Example: A ballet dancer makes use of the law of conservation of angular momentum to vary her angular speed. The torque acting on her body is zero.

**Who proposed angular momentum quantum number?**

History. The angular momentum quantum number came from the Bohr model of the atom, as proposed by Arnold Sommerfeld. The lowest quantum number from spectroscopic analysis had an angular momentum quantum number of zero.

**What is the SI unit of angular momentum?**

Appropriate MKS or SI units for angular momentum are kilogram metres squared per second (kg-m2/sec).

## Who discovered conservation of energy?

Julius Robert Mayer

In 1842, Julius Robert Mayer discovered the Law of Conservation of Energy. In its most compact form, it is now called the First Law of Thermodynamics: Energy is neither created nor destroyed.

## Who discovered p MV?

Pretty sure it was Newton who formulated it mathematically via F=ma. But, Wikipedia has a brief timeline of people who thought about it in one form or another.

**How was the Earth’s rotation discovered?**

He called together a group of scientists, enticing them with a note declaring, “You are invited to see the Earth turn.” Foucault hung a pendulum from the ceiling of the Meridian Room of the Paris Observatory. As it swept through the air, it traced a pattern that effectively proved the world was spinning about an axis.

**What is law of conservation of angular momentum Class 11?**
