Overview

This chapter explores the fundamental concepts of force and motion, building upon Galileo's and Newton's revolutionary ideas that changed our understanding of why objects move. We learn about the relationship between force, mass, acceleration, and momentum through Newton's three laws of motion, whic

Key Concepts

Force is a push

Force is a push, pull, or hit that can change the state of motion of an object, alter its shape, or change its direction. Though we cannot see force d

Balanced forces are equal in magnitude

Balanced forces are equal in magnitude but opposite in direction, causing no change in motion. Unbalanced forces cause acceleration or change in motio

An object at rest stays at

An object at rest stays at rest, and an object in motion stays in uniform motion in a straight line, unless acted upon by an unbalanced force. This te

Inertia is the natural tendency

Inertia is the natural tendency to resist change in motion. Mass is the quantitative measure of inertia - heavier objects have more inertia. A train h

The rate of change of momentum

The rate of change of momentum is proportional to the applied force and occurs in the direction of force. Mathematically: F = ma, where F is force, m
