Overview

The Laws of Motion form the foundation of classical mechanics, explaining how objects move and interact with forces. These principles, developed by Sir Isaac Newton, help us understand everything from falling objects to planetary motion. This chapter explores force, motion, inertia, momentum, and gr

Key Concepts

Force is an external effort

Force is an external effort in the form of push or pull that produces or tries to produce motion in a static body, stops or tries to stop a moving bod

Inertia is the inherent property

Inertia is the inherent property of a body to resist any change in its state of rest or uniform motion. It depends on the mass of the object—greater m

Linear momentum (p) is the product

Linear momentum (p) is the product of mass and velocity of a moving body: p = mv. It measures the impact of force on a body and is a vector quantity a

This law states that every body

This law states that every body continues to be in its state of rest or uniform motion along a straight line unless acted upon by an external unbalanc

This law states that force acting

This law states that force acting on a body is directly proportional to the rate of change of linear momentum, and this change occurs in the direction
