This is after Isaac Newton, not fig newtons, even if they are tasty. It is said that Isaac Newton got the idea for gravity when an apple fell off a tree and hit him on the head.This force is in the exact opposite direction. In the example where you kicked the ball there is the force of your foot on the ball, but there is also the same amount of force that the ball puts on your foot. This means that there are always two forces that are the same. The third law states that for every action, there is an equal and opposite reaction. This seems kind of obvious to us, but having an equation to figure out the math and science is very helpful to scientists. This also means that the harder you kick a ball the farther it will go. There is even an equation that says Force = mass x acceleration or F=ma.
The second law states that the greater the mass of an object, the more force it will take to accelerate the object. Gravity pulls the ball down to the ground and the air resistance slows it down. These include resistance or friction from the air and gravity. When you kick a ball, forces start to act on it immediately. That means if you kick a ball it will fly forever unless some sort of forces act on it! As strange as this may sound, it's true. The first law says that any object in motion will continue to move in the same direction and speed unless forces act on it. He also described how gravity works, which is an important force that affects everything. Also, the harder you kick the ball the stronger the force you place on it and the farther it will go.Ī scientist named Isaac Newton came up with three Laws of Motion to describe how things move scientifically. That is the direction the ball will travel.
For example when you kick a ball you are exerting force in a specific direction. To describe a force we use the direction and strength.
