I am going to be explaining how the four forces can help a plane get flight. The four forces are Gravity/Weight, Lift, Thrust and Drag. Which are all different types of forces. Now I will explain how each force helps a plane get flight.
Gravity/Weight – If there is too much weight on the plane the plane will start to fall to the ground. That is why at the airport they have to way your bags to make sure it is not too heavy to go one the plane. Gravity pushes the plane just a little bit so it doesn’t go too high up. When you go down to land that gravity is pushing the plane down as well.
Lift – Lift is what keeps the plane up in the air and flying. It helps the plane keep air and not go down. It is kind of pushing the plane upwards. It helps the plane to stay straight and move in a straight line. It helps the plane move up when the plane has just taken off. Lift pushes the front of the plane upwards for the plane to get high in the sky.
Thrust – Thrust helps the plane move forward to the location you are going to. It is pushing the plane and is helping the plane move faster. It is giving the plane just a little bit more speed. It is like a little booster for the plane. Thrust pushes the back of the plane, that is why on the back of the wings that have something hanging for the thrust to push that.
Drag – Drag is what slows the plane down. That is why on planes you will see the front/nose of the plane is pointy because it pushes most of the drag out of the way so the plane will only have a little drag. The way the plane turns is because the wing flaps go up on the side they need to turn too and so that side will slow down for the other wing to move that direction. When you are landing the wing flaps will come help and the drag will be pushing against both the wing flaps for the plane to slow down and have a safer landing.
