"The speed at which an object rotates or revolves is called rotational speed. Unlike linear speed, it is defined by how many rotations an object makes in a period of time. The formula for rotational s ...

"Rotational inertia measures how much an object resists changing rotation. In linear motion, according to Newton's Second Law, we use mass to gauge an object's resistance to change but in rotational m ...
"It is important to understand the difference between rotations and revolutions. When an object turns around an internal axis (like the Earth turns around its axis) it is called a rotation. When an ob ...

"The motion of any object is only meaningful when given relative to something else. Relativity in motion assures us that the laws of Physics don't vary depending on how much inertia an object has. Thi ...

"Displacement is the change in a position vector. It is not the same as distance, which is a scalar measurement. The net vector of multiple displacment vectors if found according to the rules of vecto ...

"Radiant energy is a type of thermal energy transfer involving electromagnetic waves. In the case of visible light, radiant energy is visible to the human eye. However, in all other cases, it is not v ...

"All electrons have four quantum numbers which describe the location of electrons in the electron cloud of an atom. The principle quantum number (n) describes the size of the orbital the electron is i ...

"When an object is moving through space this object is called a projectile. Examples of projectile motion include a pen falling off a table, a ball thrown through the air or a cork shot from a champag ...

"Convection is the movement of warm particles within fluids. Convection is often found in the air as heated air rises and cool air falls. This is because hot molecules spread apart, making them less d ...
