Newton's three laws of motion Newton's Laws can help us to understand how cars bikes and many other things move even people let's talk a little bit about when we see them in everyday life in simple terms the first law or law of inertia occurs when an object remains still unless something or someone moves it the second law is used to explain why it takes less Force to make a bike move forward than something that's heavier like a car and the Third Law of action and reaction happens when you throw a ball against a wall and it bounces every action no matter how small or simple has a reaction before exploring each of these laws let's go over the meaning of motion force and acceleration these three concepts are the key to understanding Newton's Laws we all know what motion is when something goes from one place to another or changes its position for example as this duck walks it's moving to a new place but it also moves when it simply lowers its head to drink some water changing its position force is when any action such as dropping pushing or dragging causes an object to move or change its shape Joan wants to pick up the box that's on the floor and put it on the table so she's using Force when she grabs the box and lifts it up she's making the box change places but if Jones tired and leans on the box she's also exerting force her body causes it to change shape lastly there is acceleration acceleration describes when something like a car speeds up or when it slows down these three key words in mind as you learn about each law Newton's Laws of Motion are happening all around us they can help us to make sense of the world and to see things in a unique way check out our other videos to learn more about each of the three laws GCF global creating opportunities for a better life
