1. What is Physics?

Physics is the branch of science that studies matter, energy, force, motion, space, and time. It explains how the universe works—from the motion of a ball to the working of satellites.

Physic builds the foundation for Chemistry, Engineering, Medical Science, Technology, and Space Science.

2. Why Physics is Important for Students

• Improves logical and analytical thinking
• Essential for competitive exams (JEE, NEET, Olympiads)
• Helps understand real-life applications
• Builds problem-solving confidence

3. Major Branches

Branch	Focus Area
Mechanics	Motion, force, laws of motion
Thermodynamics	Heat and energy
Electromagnetism	Electricity & magnetism
Optics	Light & vision
Modern Physics	Atoms, nuclei, quantum physics

4. All Classes (CHEMASH Guidance)

• Class 6–8: Concept clarity, visuals, daily-life examples
• Class 9–10: Board-focused theory + numericals
• Class 11–12: Advanced numericals, derivations, competitive prep
• JEE / NEET: High-level problem solving & accuracy

5. How to Study – Exam Oriented (2026)

Understand Concepts

Never memorize formulas blindly. Understand derivations.

Daily Numerical Practice

Physic improves only by solving problems.

Diagram & Visualization

Draw diagrams for every question.

Revision Strategy

Revise formulas weekly. Analyze mistakes.

6. Numerical Problem Solving (CHEMASH Solutions)

Q1. A body travels 100 m in 5 s. Find its speed.

Solution:

Speed = Distance ÷ Time
= 100 ÷ 5 = 20 m/s

Q2. Find force when mass = 10 kg, acceleration = 2 m/s².

Solution:

F = ma = 10 × 2 = 20 N

Q3. A machine does 500 J work in 10 s. Find power.

Solution:

Power = Work ÷ Time = 500 ÷ 10 = 50 W
