Physics

The momentum of an isolated system of two or more than two interacting bodies remains constant.

Momentum of a body is the quantity of motion it has due to its mass and velocity.

On the basis of his observations, Newton concluded that the force which triggers an apple to fall on the Earth and the force which keeps the moon in its orbit is of the very same nature.

A wave is a disruption in the medium which causes the particles of the medium to undergo vibratory motion about their mean position in equal intervals of time.

Sir Isaac Newton’s three laws of motion describe the movement of huge bodies and how they interact. While Newton’s laws might seem obvious to us today, more than 3 centuries ago they were thought revolutionary.

Friction is a tangential resistant force between two surfaces that oppose the motion of moving objects. Friction is a force that enters the action as soon as a body is pushed or pulled over a surface.

A scale is indicated around the thermometer. The warmth of the body in touch with the thermometer can be read on that scale. Three scales of temperatures are in common usage. These are:

Centripetal force is a force which maintains an object to move into a circle. Any motion in a curved path shows accelerated movement and demands that the force directed toward the middle of the curvature of the path.

The specific heat of a substance is the quantity of heat required to raise the temperature of 1-kilogram mass of the substance through 1Kelvin. The specific heat capacity of the material is a physical attribute.

Ohm’s Law is among the most fundamental and significant laws regulating electronic and electrical circuits. It relates current, voltage and resistance for a linear device, such that if two are understand, the third could be calculated.
