Physics 12th Motion Notes: 

When we study motion in Class 12 Physics, it’s not just about memorizing formulas, but about truly understanding how objects move around us. I still remember when I first learned motion, I started observing how a car speeds up, how a ball falls, or how planets revolve. Let’s walk through this topic together in simple language.

What is Motion?

Motion is the change in position of an object with respect to time. In our daily life, everything we see—cars, trains, birds, even ourselves—shows some form of motion.

Types of Motion

1. Linear Motion – When an object moves in a straight line (like a car on a highway).
   
   

2. Circular Motion – When an object moves around a fixed path (like the hands of a clock).
   
   

3. Oscillatory Motion – When an object moves back and forth (like a pendulum).
   
   

Key Terms You Should Know

• Displacement: The shortest distance between the initial and final point.
  
  

• Velocity: Speed with direction.
  
  

• Acceleration: Change in velocity with time.
  
  

• Uniform Motion: Motion with constant speed.
  
  

• Non-uniform Motion: Motion with changing speed or direction.
  
  

Important Formulas of Motion

1. v=u+atv = u + at
   
   

2. s=ut+12at2s = ut + \tfrac{1}{2}at^2
   
   

3. v2=u2+2asv^2 = u^2 + 2as
   
   

(where u = initial velocity, v = final velocity, a = acceleration, t = time, s = displacement)

I always suggest students to practice these formulas with real-life examples like calculating the speed of your bike, or the time taken by a train to stop.

Why Motion is Important in Physics?

By understanding motion, we can explain how rockets are launched, how planets revolve, or even how athletes run in the Olympics. This makes Physics more exciting because it connects directly to our lives.

Conclusion

Motion in Class 12 Physics is not just a chapter—it’s the foundation for higher studies in engineering, mechanics, and technology. If we read and practice together, we’ll find Physics more fun and easier than we thought.

I believe once you study these notes, you’ll not only perform better in exams but also come back here whenever you want a quick and clear revision of Physics Motion.
