⚡ Inertia
An object's resistance to changes in motion. Heavier objects (greater mass) have more inertia and are harder to accelerate or stop.
🎯 Momentum
The quantity of motion an object has (mass × velocity). Heavier and faster objects have more momentum and are harder to stop.
💪 Force
A push or pull that causes acceleration. The same force produces less acceleration on heavier objects (F = ma).
🔄 Newton's First Law
Objects in motion stay in motion unless acted upon by a force. Notice how objects keep moving until friction stops them.
⚖️ Newton's Second Law
F = ma. Apply the same force to different masses and observe how lighter objects accelerate faster.
💥 Collisions
When objects collide, momentum is conserved. Watch how heavier objects push lighter ones more easily.
