Module 3: Energy, Work, And Power

This section explores the fundamental concepts of energy, work, and power, detailing their interrelations and practical applications.

Energy: The Fundamental Ability To Cause Change

Energy is the capacity to do work or cause change, playing a crucial role in all physical phenomena.

Work: The Mechanism Of Energy Transfer

Work in physics is defined as the energy transferred to or from an object through the application of force causing displacement.

Power: The Rate Of Energy Transfer

This section defines power as the rate of energy transfer or the rate at which work is done, emphasizing its importance in understanding the efficiency of systems and machines.

Efficiency: The Ratio Of Useful Output To Total Input

Efficiency measures how effectively a machine or system converts input energy into useful output energy, often resulting in some energy loss due to factors like friction.

Simple Machines: Making Work Easier

This section explains how simple machines help reduce effort in tasks by changing the direction or magnitude of force, emphasizing concepts like mechanical advantage.

Module 3 Assessments

This section outlines assessments designed to evaluate students' understanding of energy, work, and power concepts.
