Over the past 100 years, the airplane has been remodeled, re designed, and innovated in many different ways. It was started off with an extremely simple design that only had a 12 horsepower engine to thrust it along the way. In 1917 they came out with the first all metal airplane and it was known as the Junkers J-4. Later on, in 1928 the first electronic flight simulator was introduced to the public. In 1932 a major curveball was thrown into the airplane innovation process.
Newton’s Third Law: - ‘For every reaction, there is an equal and opposite reaction’ - (Hall, 2015). If an object (Object A) exerts a force onto another object (Object B), Object B will exert the same force back, just in the opposite direction. A finger is exerting a force on to the wall. According to Newton’s Third Law of Motion, the wall should be exerting the same amount of force, just in the opposite direction, to the finger. Usually, the force exerted by the finger will never be enough to move the wall, so the wall remains still.
The total magnitude of the net force is determined by gravity, friction, and the amount of force the skater applies. Newton’s Second Law of Motion is an important aspect of figure skating. Newton’s Third Law of Motion states that for every action there is an opposite and equal reaction. As the skater pushes off from the ground, the ice provides a reaction to propel them. Every single action that the skater makes will have a reaction.
Title: Determine how mass affects the way an object is pulled by gravity Aim: To find out the effect of mass on the falling time of an object from a specific height. In this experiment we will be dropping three different balls with different masses from a specific height and recording the time it takes to hit the ground. Hypothesis: The ball that is heavier/has more mass will hit the ground faster than balls that are less heavy/have less mass. Materials: • One 1m ruler • Three different balls with different masses (softball, hollow plastic ball, and ping-pong ball • Stop watch Variables: Independent: • Mass of each of the balls will not change after various trials Dependent: • Time it takes for the ball to hit the ground might be different after each trial Controlled: • Height at which ball is dropped • Ball dropped at rest/initial speed Method/Procedure: 1. Support 1m ruler vertically against the wall 2.
There have been 250,000 miles of test flights which pushed the aircraft to its limits in different categories. Only when all tests were successfully completed was the aircraft received official certification. The aircraft is the first aviation aircraft in America since the end of the Second World War. The Boeing 337 Stratocruiser is a civilian version of the plane Boeing 29 Superfortress. The aircraft was known to be successful in the war as it helped with the surrender of the Japanese army by dropping the atomic bombs on Hiroshima and Nagasaki several years ago.

Newton’s first law states that an object at rest stays at rest, and an object in motion stays in motion. With this being said, a rugby kick perfectly utilizes the first law. While the ball is placed upright ready for the kick, it may remain at rest like that, until a force is acted onto it. Once the kicker kicks, hence applying FA, the ball will adopt a projectile trajectory into the sky, and would remain that way flying if it could, if it wasn’t for the force of gravity pulling it back down. Newton’s second law states that the acceleration of an object is dependent on the net force acting on the object, and the mass of that object.
