Force: * Force is essentially a push, or a pull action, that can lead to certain outcomes. * It can deform a body or can change the state of motion of a body. * Mathematically, it is the product of mass and acceleration. * Some examples of force are gravitational ... Read More

The space between two molecules or atoms is known as intermolecular space. It is very little or no intermolecular space in solids, inter-molecular spaces are moderate in liquids and maximum intermolecular spaces in gases. Intermolecular forces are the forces of attraction or repulsion between adjacent particles (atoms, molecules, ... Read More

The study of shape, size, position, and dimension of things would come under the branch of mathematics known as Geometry.Shapes such as squares, circles, rectangles, and triangles are some examples.

SI unit of Current : The SI unit of current is ampere. It is denoted by 'A'. It measures the flow of electric charge across a surface at the rate of one coulomb per second. Since the charge is measured in coulombs and time in seconds, the unit is coulomb/Sec ... Read More

In an electrical circuit, the electric potential difference between two points (E) is defined as the amount of work done (W) by an external agent in moving a unit charge (Q) from A to B.The Unit of potential difference is joules per coulomb, which is also given the name volt ... Read More

• Diagonal is a line segment that connects the opposite corners of a polygon through its vertex.• Vertex is a corner of the shape.For example, ABCD is a square and AC is the diagonal of this square because it connects opposite vertex A and C.

Physics is a branch of science concerned with the nature and properties of matter and energy. It deals with mechanics, heat, light and other radiation, sound, electricity, magnetism, and the structure of atoms.

Physical Quantity :  * A physical quantity is the measurable property of an object or a system. * Mass, time, speed, acceleration, temperature, force, pressure, power, energy and length are all physical quantities. * Physical quantities are measured by comparing them with arbitrarily chosen internationally accepted standards ...

The change in which chemical properties of the matter change is known as chemical change. During a chemical reaction, the chemical bonds between the molecules are broken and rearranged, and new bonds are formed resulting in the formation of new compounds. For example, a photosynthesis reaction is a chemical ... Read More
