The branch of physics which deals with the motion of particles and bodies under the action of given force is called:
Correct answer: C. Mechanics
- A. Solid state Physics
- B. Quantum Mechanics
- C. Mechanics
- D. Nuclear Physics
Explanation
Mechanics is the branch of physics that deals with the study of motion, forces, and energy. Classical mechanics, which includes both Newtonian mechanics and Lagrangian mechanics, is concerned with the motion of macroscopic bodies under the influence of forces. It provides a framework for understanding the motion of objects, whether they are at rest or in motion, and the forces acting upon them.

About Measurements
Physical quantities are expressed with SI base and derived units, while measurement limits are described through accuracy, precision, absolute and percentage error, and significant figures. Dimensional analysis checks equations, derives relationships and detects inconsistent units, but it cannot determine numerical constants or distinguish quantities with identical dimensions.
