Material The explanation of First Newton’s law , “Every object continues i n its state or uniform motion in a straight line unless a net external force acts on it to change that state” 𝑑𝑝 =𝐹 𝑑𝑡 𝑑 (𝑚. 𝑣) 𝑑𝑣 = 𝑚. = 𝑚. 𝑎 = 𝐹 𝑑𝑡 𝑑𝑡

Material The first newton law and second newton’s law There are many application on Newton’s first law of motion. Consider some of that is our experiment. I have observe the behavior of a let just say coffe in a cup filled to the rim while starting a car from rest or while bringir car to rest from a state og motion ? Coffe keeps doing what it’s doing. When we accelerate a car from rest, the road provides an unbalanced force on the spinning wheels to push the car forward, yet the coffe that was at rest want to say at rest. While the car accelerates forward, the coffe remains in the same position ; LER - 1

subsquently . the car accelerates out from under the coffe and the coffe probably will spill on your lap. On the other hand, when we breaking from a state of motion the coffe continues forward with the same speed and in the same direction.

Opportunity

Because all this time knowing the newton law was limited to theory, at the beginning of the study I needed some time to reunderstand this law with a more complete and significant understanding. After joining this lecture, I became more aware of the many applications of newton’s law that we encounter everyday. Looks simple, but if we apply it, it will make it easier for ourselves. Such as in an emergency like our head hurt and bleeding. Blood rushes from your head to your feet while quickly stopping when riding on a descending elevator. That’s how law’s works.
