Lift “How can a heavy metal lift off the ground”? You may ask. The answer to this question is the lift of the wing, and there are two explanations about how the lift are generated. As everyone can see, the shape of the airplane wings is in a stream line form, which is flat along the bottom and curved on the top. The purpose of this design is not for pleasing to the eye, but for the perspective of physics.
The reason why helicopters stay up in the air is because the individual rotary blades are shaped like airplane wings. Once the spinning rotor assembly has reached a certain speed, the curved blades chop up the air around them, creating lower pressure above the blade and higher pressure below. This action creates a pushing or lifting force from below. The pilot uses hand and foot controls to change the angle of attack on each blade as they spin. This angle affects whether the helicopter will rise, descend, turn, or even hover.
Each air tunnel creates a tremendous amount of force (or turbulence). Just one of the air tunnels could flip a plane traveling behind it. Wind tunnels are formed from different air pressures coming together from the winglets. The air pressures do not want to mix, so they try to get away from each other by spinning around and then going in a different direction. This can help gliders because it acts almost the same as two jet engines.
Here more wing angle and surface creates more down force which in turn reduces speed. But here the rear wing is splitted into two set of aerofoil which is connected to each other. The upper aerofoil is one large single element whereas the lower one is responsible for creating down force. The lower wing when tilted to a certain angle which creates a low pressure region to create more down force below the car. The position of two wings should be relative to each other as if they were very close then the resultant force will be in opposite direction and thus cancel each other.
IBDP Physics Practice Lab - Factors Affecting the Drop Time of a Falling Body By Clevis Tam Aim: To investigate how the relationship of the terminal velocity of a falling parachute depends on the mass of the clay. Variables: • Independent Variables: The mass of the Clay (g) • Dependent Variables: The time the clay takes to reach the ground (s), The speed of the clay that is processed after collecting data (ms -1) • Controlled Variables: Method of releasing the clay, the area of the parachute Materials / Apparatus: 1. Meter Ruler (0-1m, measures to 0.001m) 2. Electronic Stopwatch (measures to 0.01s) 3. Drop Height (2.56m) 4.
Newton’s Second Law and the Work-Kinetic Energy Theorem October 13, 2010 Abstract This experiment utilizes an air track first as an inclined plane with the slider accelerating due to gravity and second as a level surface with the slider accelerating due to the pull of an attached free-falling object of known mass. In both cases, the Work performed is calculated based on formulas for mechanical work and for kinetic energy. The two results are compared. The first part yielded an average acceleration of 0.715 m/s2 (a 1.58% error) and the average result for the Work performed was 0.0204 N*m with only a 0.9% difference. The second part suffered critical errors due to improper data and the results are not significant or useful.
They all use lightweight material to fly too. Some of these kites are made from icarex polyester. This material is used on the bigger kites because it creates a better lift for kites with a wider wingspan. They whole kite can also weigh anywhere from 3 ounces to 9 ounces and they can fly anywhere between 5-25 mph. These wind speeds are just a little higher than the intermediate stunt
The first principle states that if there is no force applied to the gyro, the spin axis of the gyro wheel tends to remain in a fixed direction in space. Precession is the tilting or turning of a gyro in response to a force. For instance, whenever a plane changes direction, small perpendicular force applied to gyro. As result of, the gyro will rotate 90 degrees ahead of that point of force. Gyroscope is being used in almost every vehicle especially in airplane’s instrument such as altitude indicator, heading indicator, and turn coordinator.
Gliders have seeds attached to a super thin layers of materials giving it the ability to glide in the air. Parachutes include seeds or with an elevated, umbrella-like crown of intricately-branched hairs at the top. Helicopters include seeds with a rigid or membranous wing at one end. The wing typically has a slight pitch like a propeller or fan blade, causing the seed to spin as it falls. Plants that grow beside water often rely on water to transport their
Read on to see examples of how calculus is used in astronomy. An Essential Element Calculus is the mathematical language that describes change. One of the most common uses of calculus is to find the rate at which the position of a moving body changes with time. The laws of planetary motion that are commonly used by astronomers to calculate orbits are derived using calculus. An astronomer who wants to send a rocket into space uses calculus to work out how much fuel the rocket needs to accelerate to the correct velocity.
