Overview

Laws of Motion is a fundamental chapter in mechanics that bridges kinematics (study of motion) and dynamics (study of forces causing motion). This chapter introduces Newton's three laws of motion, which form the foundation for understanding how forces affect the motion of objects. We explore concept

Key Concepts

Every object continues in its state

Every object continues in its state of rest or uniform motion unless acted upon by an external unbalanced force. This law defines inertia as the tende

Rate of change of linear momentum

Rate of change of linear momentum is directly proportional to applied force: F = dp/dt. For constant mass, this becomes F = ma. This law provides the

To every action force

To every action force, there is an equal and opposite reaction force. These forces act on different objects, have equal magnitudes, opposite direction

Linear momentum p = mv

Linear momentum p = mv is conserved in isolated systems where no external force acts. This principle states that total momentum before interaction equ

Elastic collisions conserve both momentum

Elastic collisions conserve both momentum and kinetic energy (e = 1), inelastic collisions conserve momentum but lose kinetic energy (0 < e < 1), and

Learning Objectives

  • Understand and distinguish between inertial and non-inertial reference frames
