• ## Mass of earth and radius in physics

The planet earth has an approximate mass of 6 × 10 24  kg , or what is the same: 6000 trillion tons. This amount is used in space science (astrophysics and astronomy) as a unit of mass to calculate how heavy other planets are compared to ours. Earth is the…

• ## Difference Between Distance And Displacement

The basic difference between Distance and displacement is that distance is the length of a path between two points and displacement is the shortest distance between two points. More differences between distance Vs displacement are tabulated below. You may also…

• ## Centripetal acceleration Examples

The acceleration that controls the change in direction of motion in rotating or curving bodies is known as the centripetal acceleration or normal acceleration. Since it constantly faces the center of rotation, it is known as centripetal. The concept of…

• ## Types of Prism

What is Prism? The word prism is derived from the Latin word ” prism “, which has Greek roots and literally means ” anything sawn.” A prism is a geometric form made up of two identical flat polygons. Bases are…

• ## Applications of Pascal law

Pascal law states Pressure applied at any point of a liquid enclosed in a container is transmitted without loss to all other parts of the liquid. Hydraulic press, Hydraulic jack system, and brake system are a few applications of Pascal…

• ## Newton’s Second Law of motion: Definition, Formula & Exaamples

Newton’s second law of motion states that the rate of change of momentum of a body is directly proportional to the applied force. According to Newton’s first law of motion “if no net force is acting on a body at…

• ## Newton’s three laws of motion with examples and applications

Newton’s three laws of motion are the 3 physical laws, these laws of motion laid the foundation for classical mechanics. These laws explain the relation between forces and the body on which these forces acted upon. Newton’s first law of…

• ## What is SI Unit of density in Physics?

Density and mass are two physical quantities. Mass is the quantity of matter of an object while density is mass per unit volume. They are two different quantities but these quantities have relationships with each other, higher will be the…

• ## Scientific notation and significant figures

Scientific notation and significant figures are two important terms in physics. In scientific notation, numbers are expressed by some power of ten multiplied by a number between 1 and 10, while significant figures are accurately known digits and the first…

• ## Difference between North pole and south pole in tabular form

The Difference between the north pole and the south pole is given here. The poles of the planet share being covered with ice and having nights and days that last 6 months. However, they present differences that make them unique…
