đ„ Unang Batas ni Newton: Batas ng Inersya
Ang mga bagay na gumagalaw ay patuloy na gagalaw,at ang mga bagay na nakapahinga ay mananatiling nakapahinga,maliban kung ito ay maapektuhan ng isang hindi balanseng puwersa.
đ Paliwanag:Kung walang puwersang umaapekto, hindi magbabago ang kalagayan ng isang bagay â hindi ito hihinto o gagalaw nang kusa.
đ Halimbawa:Kapag huminto bigla ang sasakyan, parang nahihila ang katawan mo paabante â dahil gusto ng katawan mong manatiling gumagalaw.
đ§ Trivia Time!
Question:If you're riding in a car and the driver suddenly hits the brakes, why do you lurch forward?
Answer:Because of Newton's First Law! Your body tends to stay in motion even though the car stops â thatâs inertia in action. You're still moving forward until the seatbelt (an unbalanced force) stops you.
đ Newtonâs First Law â 5 Trivia Facts
Inertia is everywhere:Newtonâs First Law explains why you donât fly out of your seat when a car is moving steadily â youâre moving at the same speed until something (like brakes) changes that.
The law applies in space too:In outer space, where thereâs no air resistance, a moving object can keep going forever unless a force (like gravity) stops or changes it.
Seatbelts are real-life applications:Seatbelts save lives because they act as the unbalanced force that stops your body from continuing forward when the car stops suddenly.
Stillness is motion too:An object at rest isnât lazy â it simply follows Newtonâs First Law by staying still unless something makes it move.
Earth's friction hides the law:On Earth, we donât always see this law clearly because forces like friction and air resistance are constantly acting on moving things.
