## WORK, POWER, AND ENERGY – PART 1

There are two ways of multiplying vectors. One way known as the scalar product gives a scalar from two vectors. The other known as the vector product gives a new vector from the two vectors.

## NEWTON’S LAWS OF MOTION

Motion of the object needs the concept of Velocity and acceleration. In earlier chapter we have studied the motion but not what causes the motion?

## MOTION IN A PLANE

A physical quantity having only magnitude is called a scalar quantity. It is specified completely by a single number along with proper unit.

## MOTION IN A STRAIGHT LINE

Mechanics is the oldest and fundamental branch of physics and it is the study of the state of rest as well as the state of motion of an object under the action of force.

## UNITS AND MEASUREMENTS – PART 2

This article is formulated according to the 2nd chapter in the NCERT Syllabus of 11th Std Physics OR 1st PUC Physics. Significant figures indicate the precision of the instrument.

## UNITS AND MEASUREMENTS – PART 1

The physical quantities which are independent of each other are called fundamental quantities. There are SEVEN fundamental quantities. They are Length, Mass, Time, Electric current, Thermodynamic temperature, Amount of substance, and Luminous Intensity.

## PHYSICAL WORLD

Science is organized, systematic, and formulated knowledge obtained through observations, experiments, and verifications.

## Surprising reasons why Pluto is not a planet!

Pluto lies far from the Sun, being the ninth largest body to orbit the Sun. From its discovery in 1930 to 2006 it was the ninth planet in the Solar System.

## How did India go to Mars on its first attempt?

Indian spacecraft known as Mangalyaan or Mars Orbiter Mission (MOM) became the first Asian spacecraft to orbit Mars when it entered the orbit of Mars on 24 September 2014.
