Question

Mechanics is a branch of physics. This branch is ... (A) Kinematics without dynamics (B) dynamics without Kinematics (C) Kinematics and dynamics (D) Kinematics or dynamics

Short answer

Mechanics is a branch of Physics that includes both Kinematics (motion) and Dynamics (forces causing motion). Therefore, the correct answer is (C) Kinematics and Dynamics.

Step-by-step solution

Understand Kinematics

Kinematics is the branch of Physics that deals with the motion of objects. It does not concern itself with the forces causing the motion. It focuses on quantities such as position, velocity, and acceleration to describe an object's motion.

Understand Dynamics

Dynamics, on the other hand, is a sub-branch of Mechanics that deals with the forces responsible for causing motion. It analyzes the relationship between the motion of objects and the forces acting upon them.

Recognize the role of Kinematics and Dynamics in Mechanics

Mechanics is a broader topic in Physics that includes both Kinematics and Dynamics, as it deals with both the motion of objects and the forces that cause those motions.

Choose the correct option

Based on the above understanding, Mechanics is the study of both Kinematics (motion) and Dynamics (forces causing motion). So, the correct option is: (C) Kinematics and Dynamics.
