This means that there is more lift than gravity, which will keep the plane up. Drag is reduced by the way the plane is designed. This means there is more thrust than drag, which will keep the plane moving forward through the air. Bernoulli’s Principle says that if the speed of the air gets faster, pressure is reduced. Since air on top of an airplane’s wing goes faster on the top due to the curvature
A difference between them, however, is speed. Trains are known to be slow, whereas a plane can go extremely fast. This gives the plane some advantages over the train when it comes to being in a place at a certain time, or in other speed-related
As the roller coaster ended and more friction occur, the marble lost its momentum and the total energy and usable energy lost became the same. Some of the error in calculations is being able to time the marble just right, as it is hard to see. This is a human error that probably can’t be fixed. The area of our roller coaster that worked really well was our loop because it was very smooth and the beginning had a long drop. Something we could’ve improved on was the
The transferring between kinetic and potential energy happens throughout the ride, but, there is some energy that is not transferred back and forth between the two energies. And this would be because of friction (Energy). Friction is the force that acts against moving objects and causes them to slow down, or in this case, lose some of its kinetic energy. Friction also causes the ride to have thermal energy that has no effect on the roller coaster besides heating up some of the track (Physics). That fact is why many roller coasters have their tallest hill at the beginning, also, at the top of these hills, it is possible for riders of the coaster to experience weightlessness and feeling heavier at the bottoms of the coaster (Physics).
Though the Kennedy Space Center only has space shuttles, the physics between the flight of an airplane, and flight of a rocket are very similar. Both vehicles experience a lift force, however that of the rocket has a much greater magnitude. The weight force is much greater on the space shuttle than the airplane, due to the larger mass. A drag force is felt by both aircrafts, and again the
Some of the pros are; “significant increase in horsepower, gives smaller engines a chance to gain much more power relative to their size, gets better fuel economy with engines that use less fuel to idle, turbochargers run off gases that would be expelled through the exhaust pipe and improves the efficiency”(“The Pros and”… page 1). There are also some cons of turbochargers, and one of the main ones is called “turbo lag”. Turbo lag is caused because it takes time to spool up the turbocharger, which means you will not receive your full power boost right away. Another big con of a turbochargers is that when they finally kick in, the power surges and could result in a collision or a crash. One of the last major cons of a turbo is that they require the use of oil.
Moreover, if there were no air resistance, then the skydivers would continue accelerating until they hit the ground. For objects falling through the air, the formula is represented as: psgV – pagV – FD = psVa Where: ps =The density of the falling object pa = The density of the air it’s falling in FD = The drag force g = The gravitational force V = The volume of the falling object. a = The acceleration of the falling
If the ball is thrown hard enough the ball will come up high with the same amount of force that was used from the start. As passengers begin to push down on their seats, the seats also pushes back. Another thing that plays a part in this law is g-force. G-force is the force due to the gravity at earth’s surface. They basically push the passenger onto their seat.
