Kilogram is purely a unit of mass measurement. ‘lbs’ is the abbreviation and the official notion used to indicate pounds.

Inertia can be described as a property or tendency of an object that resist any change to its state of motion. Thus, a body stays at rest or continues its motions, unless acted on by an external force. Momentum can be described as the resistance to stop. Moving bodies are associated with momentum as it becomes a kind of inertia for them.

Velocity refers to the rate of change of distance with respect to time. It is a vector quantity, which means that it has both - a direction and a magnitude. Average velocity refers to the change in position over the time of travel. The change in position can also be referred to as the displacement.

Niagara Falls are the waterfalls located on the Niagara River. They comprise of three waterfalls - The American Falls and Bridal Veil in the United States of America and the Canadian ‘Horseshoe’ that falls in Canada. Victoria Falls are located on the Zambezi River. Victoria Falls is located in Southern Africa, on the border of Zambia and Zimbabwe. Victoria Falls is taller and wider in comparison to Niagara Falls.

Velocity refers to the rate of change of distance with respect to time. It is a vector quantity, which means that it has both- a direction and a magnitude. Angular velocity evaluates the rate of change of angular position for a spinning object with respect to time.

Superstition denotes a belief or notion that is based on irrational thoughts. It can be related to religious, cultural or personal values. On the other hand, science is a branch of knowledge that is based on the systematic study of the components comprising the physical and natural world.

Iguazu Falls are one of the largest waterfalls in the world. They are situated on the border between the Brazilian state of Parana and the Argentina province of Misiones. Iguazu falls are taller and wider than in comparison to Niagara Falls.

Nebula is a cloud in deep space consisting of gas or dirt/dust (e.g. cloud formed after a star explodes). Solar Nebula is the cloud of gas and dust that began to collapse about 5 billion years ago to form the solar system.

Nebula is a cloud and dust in space. Molecular cloud is a type of nebula. The formation of molecules is permitted due to its density and size.

‘Supernova’ is a singular term, and ‘supernovae’ is a plural of supernova. Supernova is the last stage of the life of a star.

The interstellar nursery of cloud of dust and gas is called as Nebula. Planetary nebulae is a type of nebula. They are created when a main sequence star grows into a red giant and casts off its outer layers.

Nebula is a cloud in deep space consisting of gas or dirt/dust (e.g. cloud formed after a star explodes). A group of numerous stars, dust, planets and other interstellar matter, tied together by a gravitational force is known as a Galaxy.

Nebula is a cloud in deep space consisting of gas or dirt/dust (e.g. cloud formed after a star explodes). Supernova is the last stage of the life of a star and is a very huge explosion from a dead star.
