Frequently asked Questions on CBSE Class 9 Science: Notes

What is ‘matter’?

Matter is a substance that has inertia and occupies physical space

What is ‘Gravity’?

Gravity is a natural phenomenon by which all things with mass or energy, including planets, stars, galaxies and even light, are attracted to one another.

What is ‘Sound’?

The sensation perceived by the sense of hearing is known as Sound.

What is Work And Energy ?


The work done on a system by a constant force is the product of the component of the force in the direction of motion times the distance through which the force acts. For one-way motion in one dimension, this is expressed in equation form asW=Fdcosθ W=Fdcosθ

where WW is work, FF is the magnitude of the force on the system, dd is the magnitude of the displacement of the system, and θθ is the angle between the force vector FF d the displacement vector dd.

Energy :

Energy is the capacity for doing work. It may exist in potential, kinetic, thermal, helectrical, chemical, nuclear, or other forms.

SI unit: joule

Dimension: M L2 T−2

Other units: kW⋅h, BTU, calorie, eV, erg, foot-pound
