Vary m by adding or removing mass from the glider. Repeat steps 5-11. Try at least four different values for m. Calculations For each set of experimental conditions: Use the length of the glider and your average times to determine v1 and v2, the average glider velocity as it passed through each photogate. Use the equation a = (v2 - v1)/t3 to determine the average acceleration of the glider as it passed between the two photogates. Determine Fa, the force applied to the glider by the hanging mass.
5. Compute a linear least-squares-fit of the calibration data and plot the resulting line on the same graph as the calibration data. Comment on the linearity of the pressure transducer and scannivalve. Part 3: Calibration of the Tunnel 1. Connect the micromanometer (calibrated in Part 2) across the wind-tunnel contraction in order to measure the static pressure drop.
FOR A MOMENT, THINK OF AN AIRPLANE MOVING FROM LEFT TO RIGHT AND THE FLOW OF AIR MOVING FROM RIGHT TO LEFT. THE WEIGHT OR FORCE DUE TO GRAVITY PULLS DOWN ON THE PLANE OPPOSING THE LIFT CREATED BY AIR FLOWING OVER THE WING. THRUST IS GENERATED BY THE PROPELLER AND OPPOSES DRAG CAUSED BY AIR RESISTANCE TO THE AIRPLANE. DURING TAKE OFF, THRUST MUST BE GREATER THAN DRAG AND LIFT MUST BE GREATER THAN WEIGHT SO THAT THE AIRPLANE CAN BECOME AIRBORNE. FOR LANDING THRUST MUST BE LESS THAN DRAG, AND LIFT MUST BE LESS THAN WEIGHT.
Physics 1408 Section E1 Standing Waves in a Vibrating Wire Callie K Partner: Miguel E Date Performed: March 20, 2012 TA: Raziyeh Y Abstract This lab had two purposes. The first was to determine the relationship between the length of a stretched wire and the frequencies at which resonance occurs. The second was to study the relationship between the frequency of vibration and the tension and linear mass density of the wire. In the first part we found the resonance, frequency and wavelength of a wire and used this data to calculate the speed of the traveling waves. For first harmonic, our wavelength was 1.200 m, found by the formula λ=2L/n.
Which of the following diagrams best represents the directions of the actual forces acting on the box as it moves upward after the push? 3. An ideal spring obeys Hooke's law, F = kx. A mass of 0.50 kilogram hung vertically from this spring stretches the spring 0.075 meter. The value of the force constant for the spring is most nearly (A) 0.33 N/m (B) 0.66 N/m (C) 6.6 N/m (D) 33 N/m (E) 66 N/m 4.
Identify the controlled variables. A.) Make two airplanes. One small with long wings and one long with short wings. Have two people fly it and see which plane goes the furthest, making sure to match the same amount of force used to throw the planes.
For the elastic collision we had the gliders set up so they would bounce off each other when they collided. We tracked each glider from both sides of the track and used the velocity to calculate momentum, before and after. The inelastic collision had the same setup, but the gliders were now setup to stick together when they collided. This was done with Velcro strips that stuck together when they met. Data and Analysis The following table shows the values we got during the elastic collision Elastic Data | | Pred | Pblue | Δp | | 0.04 | -0.07 | 0.03 | | 0.01 | 0.07 | 0.08 | | 0.2 | -0.3 | 0.1 | Average | 0.09 | -0.09 | 0.06 | Our uncertainty is calculated using the general formula for multiplied/divided values giving us an error of 0.1 kg*m/s.
a. the space shuttle as it is orbiting Earth b. a car turning a corner c. the space shuttle when it is being launched d. a bike moving in a straight line at a constant speed 3. If you triple the net force acting on a moving object, how will its acceleration be affected? ______ 4. The gravitational force between two objects depends on which of the following? a. each object’s mass c. the distance between the objects b. each object’s volume d. both (a) and (c) 5.
We know that as the mass doubles, the KE doubles, but as the speed doubles, the KE quadruples [2]. This becomes important when analysing this formula: KE = GPE/0.5mv2 = mgh [3] This shows the mathematical relationship between KE and GPE. This formula is in effect as the “car” is falling or rising a hill. The formula shows, that the KE gained, is equal to the GPE lost, and vice versa. To analyse this further, we can observe Newton’s first law of motion.
They are, thrust, the forward motion or speed of the paper airplane, for our paper airplanes this is provided by your throwing the plane forward. Second is drag, which is the resistance of the aircraft against the wind. Third is gravity, the force that pulls down all things on the Earth. To alleviate this force an object needs to become light in weight. Last is lift, where the push of the wind under the wing is greater than the push on top of the wings.
