For all grade 12 students, as we did last year, we also continue to do the same work for you. We shared some different work sheet, poll questions, and some pdf last year. We also do the same in this year. So you can use this channel with free. No need any payment. So please start preparing yourself from now for national exam of 2018.
Please share this channel for your friends. Thank you! Keep up your studying!

Law of Inertia ๐
The first law of motion, also known as the law of inertia, states that an object at rest will remain at rest, and an object in motion will continue to move with a constant velocity, unless acted upon by an external force.
1. Inertia: The tendency of an object to resist changes in its motion.
2. External Force: A force that acts on an object from outside, causing it to change its motion.
3. Constant Velocity: An object will maintain its velocity unless an external force acts upon it.
Applications
1. Understanding Motion: The first law of motion helps us understand how objects move and respond to forces.
Real-World Examples
1. Seatbelts in Cars: Seatbelts help prevent injury by restraining passengers and preventing them from being thrown forward when a car suddenly stops.
2. Objects in Motion: A bowling ball will continue to move in a straight line unless friction or another external force slows it down or changes its direction.
