Study Plan

1
Day 1–2

Learn the Theory

Read the textbook chapter carefully. Note down definitions, formulas and key ideas. Focus on: 1. Work and its conditions, 2. Units and relation of work with energy, 3. Mechanical energy: potential energy and kinetic energy.

2
Day 3

Practise

Solve the textbook exercises and extra practice questions. There are 44 questions available for this chapter.

3
Day 4

Revise & Test

Revise key points without looking at your notes. Take a practice quiz and mark weak areas for another pass.

Day 7

Spaced Revision

Come back to Work and Energy after a week. Use flashcards for quick recall and try past exam questions on this chapter.

What to Focus On

  • Work needs both force and displacement.
  • No displacement means no work.
  • Perpendicular force and displacement give zero work.
  • Energy means ability to do work.
  • Energy and work have the same SI unit: joule (J).
  • Not all energy is always converted into useful work.
  • Mechanical energy has two parts.
  • Potential energy is due to position.
  • Kinetic energy is due to motion.

Common Mistakes to Avoid

Any force applied on a body means work is done.

If a person feels tired, work must have been done in the physics sense.

Work depends only on the size of the force, not on the direction of displacement.

Memory Tips

Definition of work

Zero work when force is applied but no movement occurs

Zero work when force and displacement are perpendicular

Work done with force at an angle
