Solutions of Physics from RRBS NTRC

This topic discusses units and measurements. It talks about standard unit of measurement, which is a quantifiable language that helps everyone understand the association of the object. It briefs on physical, scalar and vector quantities.

This topic discusses motions and the laws of motion. It briefs on projectile, circular and rotational motion. It explains Newton's first, second and third laws of motion. It also illustrates equations of motion.

This topic explains the concept of force, which is a push or pull upon an object resulting from the object's interaction with another object. It also briefs on linear momentum, centripetal force, centrifugal force and impulse.

This topic details work, power and energy. It defines work, power and energy and mentions their units of measurements. It further discusses kinetic energy, potential energy and the transformation of energy.

This topic talks about gravity, also called gravitation, which is a force that exists among all material objects in the universe. Here, it covers concepts such as centre of gravity, Earth’s gravity, escape velocity, escape energy, etc.

This topic explains the properties of solids and liquids. A solid has a definite volume and shape, a liquid has a definite volume but no definite shape. It covers related concepts such as elasticity, pressure, buoyancy, surface tension and density.

This topic deals with the concept of heat, which is the energy that is transferred from one body to another as a result of a difference in temperature. It discusses temperature and its measurement, transmission of heat, specific heat capacity, etc.

This topic explains the concept of waves, which can be described as a disturbance that travels through a medium, transporting energy from one location to another without transporting matter. It discusses mechanical waves, electromagnetic waves, etc.

This topic describes the concepts related to light. Here, it explains the reflection of light, refraction of light, scattering of light, and dispersion of light. It also discusses mirror, lens and optical instrument.

This topic explains the concept of electricity and magnetism. Electromagnetism is a branch of physical science that describes the interactions of electricity and magnetism. It also mentions some important magnetic substances and their elements.

This topic talks about Nuclear physics, which is the study of atomic particles such as protons, neutrons, and electrons and their structure, functions and uses. It briefs on nuclear reactions and nuclear reactors.

This topic explains the concept of semiconductors, materials which have a conductivity between conductors and nonconductors or insulators. It briefs on extrinsic semiconductor and its types such as n-type and p-type semiconductors.
