GCSE Physics - Newton's 1st & 2nd Laws | Circular Motion | Inertia (2026/27 exams)

⭐️ Check out our website https://www.cognito.org/ ⭐️

*** WHAT'S COVERED ***

1. Newton's First Law of Motion
   • The role of resultant force in changing an object's motion.
   • How the law applies to stationary and moving objects.
2. Newton's Second Law of Motion
   • The relationship between a non-zero resultant force and acceleration.
   • How acceleration affects an object based on its initial motion (speeding up, slowing down, changing direction).
3. Circular Motion as an example of acceleration
   • The difference between constant speed and changing velocity.
   • How gravitational pull acts as the resultant force causing acceleration in an orbit.
4. The equation F = ma
   • The relationship between resultant force, mass, and acceleration.
   • A worked example of calculating acceleration.
5. Inertia and Inertial Mass
   • The definition of inertia as the tendency for motion to remain unchanged.
   • Inertial mass as a measure of how difficult it is to change an object's velocity.
