Principles Of Physics For Senior Secondary School By Nelkon

Physics – branch of science that studies matter and its motion through space and time, along with related concepts such as energy and force. Physics is one of the "fundamental sciences" because the other natural sciences (like biology, geology etc.) deal with systems that seem to obey the laws of physics. According to physics, the physical laws of matter, energy and the fundamental forces of nature govern the interactions between particles and physical entities

Physics – branch of science that studies matter[9] and its motion through space and time, along with related concepts such as energy and force.[10] Physics is one of the "fundamental sciences" because the other natural sciences (like biology, geology etc.) deal with systems that seem to obey the laws of physics. According to physics, the physical laws of matter, energy and the fundamental forces of nature govern the interactions between particles and physical entities (such as planets, molecules, atoms or the subatomic particles). Some of the basic pursuits of physics, which include some of the most prominent developments in modern science in the last millennium, include:

• Describing the nature, measuring and quantifying of bodies and their motion, dynamics etc.
  • Newton's laws of motion
  • Mass, force and weight (Mass versus weight)
  • Momentum and conservation of energy
  • Gravity, theories of gravity
  • Energy, work, and their relationship
  • Motion, position, and energy
  • Different forms of Energy, their inter-conversion and the inevitable loss of energy in the form of heat (Thermodynamics)
  • Energy conservation, conversion, and transfer.
  • Energy source the transfer of energy from one source to work in another.
• Kinetic molecular theory
  • Phases of matter and phase transitions
