Impact of Jet

So when the shoot of the rocket, on the ground takes off there will be some things that affect the velocity. Onething that will affect the velocity are pebbles on the ground. Another thing that might affect the velocity, is if the launch takes place on a hill or not, because it would gain speed but if we launch it up a hill then it will slow the velocity down. And lastly, if there was a crack in the ground and someone filled it with tar, that will make a little of the speed slow down because it is a little bump. “Rapidity or speed of motion; swiftness” is velocity. ( definition.org ) One reason that the speed of the rocked slowed down was because of gravity pushing down on the bottle rocket. In the very beginning the rocket will be going fast but then it will be slowing down because all of the fuel is being used and also because of

Set the radius to 2.0 m, the mass to 1.0 kg, and the velocity to 10.0 m/s.

As a result of the experiment and computation of data, the aerofoil was found to have a critical Mach number of M=0.732. Below this freestream Mach number the Prandtl-Glauert law predicted results very

However, there are some other factors that affect the fall rate of the marble, including; size and the shape of the marble. Therefore, the marble undergoes drag force and the effect of gravity, which all accounts for hydrodynamic forces. Hydrodynamic forces are the forces which slow the snow as it moves through liquids. In this experiment, turbulent flow can affect the snow’s timing to reach the base of the breaker in water as the flow of the fluid is

Loosen the retaining screw and adjust the horizontal arm to the dimple that produce the 2nd largest radius between the spinning mass and the rotating shift. Allow the spinning mass to hang straight down, without being connected to the spring. Position the pointer directly below the tip of spinning mass and secure the pointer to the base. Use the scale located on the base to determine the radius, r, of the pointer from the rotating shaft. Record this value onto Data Sheet A. The experimental uncertainty in r is estimated to be the width of the spinning mass tip – approximately 0.2 cm.

If we measured in meters then a=4.9.) t is the time in seconds, v0 is the initial velocity of 30 feet per second, and s0 is the initial height or 4 feet. Thus we have:

After doing this problem, I found that I am very comfortable using the kinematic equation of vf = v​i​​+at, when I use this equation I find that I always get the right answer for the problem, which is great, and I have no further questions to help me understand this

The aim of the experiment is to examine how the acceleration of the car differs when the angle of inclination of the ramp is amplified and to record and analyse findings.

Let the mass of the fired bullet be Mb. It is fired at an initial velocity of v. The momentum

In this experiment in a low speed flow the static pressure around an aerofoil will be observed and discussed. The lift on the aerofoil will also be calculated and compared with the theoretical value. The aerofoil being used in this particular experiment is symmetrical and is taking place in a wind tunnel with a speed of 18.5m/s, therefore the flow is assumed to be incompressible. The different pressures along the surface of the aerofoil will be measured at an angle of attack of 4.1 degrees and 6.2

Assuming no viscous forces present an inviscid model has been used for the calculations. Also from the equation of the Reynolds number Re=ρvl/μ due to Re being really big rearranging and assuming v and l to be constant the viscous force μ =ρvl/Re becomes negligible.

Ever since I was little I was amazed at the ability for a machine to fly. I have always wanted to explore ideas of flight and be able to actually fly. I think I may have found my childhood fantasy in the world of aeronautical engineering. The object of my paper is to give me more insight on my future career as an aeronautical engineer. This paper was also to give me ideas of the physics of flight and be to apply those physics of flight to compete in a high school competition.

6. The outflow rate is measured by using a measuring cylinder. It is measured 3 times and averaged for a more accurate result. The results are shown in Table 2.

Step 9: Because we measured the lengths in centimeters rather than meters, we need to calculate are ‘g’ value into m/s2 so we can compare it to the SI unit for acceleration due to gravity. (Eg. 981.4/100 = 9.81 m/s2)

The forces that are involve with the experiments are basically focused on the concurrent forces. The experiment also allows us to develop the condition of balancing or arranging the angles both sides on a force table. This laboratory experiment allows us to take the mathematical abstraction of a vector to make it tangible as possible. This experiment will look into two ways of
