Terminal Velocity vs Area of a Falling Object

terminal velocity lab report

This condition can exhibit lethargy, vomiting and not being able to breathe. With this information we than discovered the average acceleration, mine was. Coffee filters were chosen because they are light enough to reach terminal velocity in a short distance. Measurements and prediction of terminal velocity of solid particles falling through stagnant pseudoplastic liquids. Drag on spheroidal particles in dilatant fluids.

Drag force on a sphere in creeping motion through a Carreau model fluid. We all were different and did the roles we were good at. Figure 6 Figure 7 shows the results table in the Data Analysis Toolkit. What was the percent error on your experimental value for the area? After that we were able to find δa, then finally the free-fall acceleration, I got 1. As the object falls through air it experiences drag force or air resistance that acts upwards and opposes gravity Encyclopedia Britannica. Determine the parameters K flow consistency index and n flow behavior index.

PhysicsLAB: Terminal Velocity

terminal velocity lab report

Introduction: This lab is an experiment in terminal velocity, the speed an object cannot surpass due to frictional forces. The rheological characterization involves steady shear-viscosity and dynamic oscillatory-shear measurements to quantify the viscous and elastic properties respectively. For each of the four runs, CloudLab then calculates the mean value for the three trial results in each run and fills in those values automatically for us. With the sensor device we had to take out points when group member A had pressed start, but group member B had not reacted and dropped the filter. By using a motion detector and force sensor, we were able to determine the forces of static and kinetic friction of the block with and without weights. This would impact results as we are also measuring the time it takes the object to reach terminal velocity. The error bars shows the variability in the three measurements.

The surface are should not change either the cupcake liners are stacked , so we can also ignore that value. The air resistance force of friction that causes terminal velocity is caused by a few things. This condition is caused by the excess amount of nitrate that is then converted into nitrite by the digestive system. Since we are interested only in the magnitude, we key in 1. Marbles of different sizes 5.

Confining walls reduce the settling velocities by exerting a retardation effect on particles. The plot shows the viscosity of fluid as a function of shear rate. We were able to calculate the coefficient of kinetic. How much time will it take the police car to catch the fugitive? Risk Assessment: A risk assessment is undertaken to identify and address potential hazards in experiments. Position phone to record total motion of coffee filter s as it falls. The observable trends that were seen throughout the results were, while average speed increased so did the final, portraying a direct correlation between the two. Once all the needed chemicals were added we waited for about 70-75mintues for the reaction to take place.

Another example is hitting a golf ball, which can be in kinematics or in dynamics. Factors such as the mass of the balloon can also be tested in further research, allowing us to see the correlation between mass and terminal velocity. What was the slope of your trend line on the graph of average terminal velocity squared vs mass? Various numerical predictions 14-18 and experimental studies 19-24 are available in literature to determine the drag force on a sphere in inelastic power-law fluids. Different student groups are likely to get somewhat different powers but all should be inverse power relationships. Place your answers in the first data table below.

The parabolic curve opens upward in the position vs. The time it took for the group member B to drop the filter, after group member A presses start. As the paper falls to the ground air resistance is pushing the paper up, this slows the acceleration of the paper. If the object was thrown with a non-zero initial velocity it would take less time for it to reach terminal velocity. At the far right of each trial are three icons. We needed for this experiment a hot plate, clamps, pipette, 5mL vial, caps, hoses and a thermometer. Introduction: The average person might hear the word physics and have no idea what it really means.

The formal definition is; a science that deals with matter and energy and their interactions. In most cases time had a direct relationship with average speed, being that it increased it. The experimental procedure, including the image analysis, should be validated by performing some preliminary experiments in unbounded Newtonian fluids e. Many theoretical and experimental studies to determine wall factors for spheres settling in Newtonian fluids in different cross-section tubes over a wide range of Reynolds numbers are available in the literature 7-13. Estimate the rate of change from a graph. The fit is also shown on the same plot.

The detailed results along with the analyses can be found in an earlier publication 43. Physics with Vernier See other experiments from the lab book. The fugitive grabs a motorcycle and stars it accelerating at the same rate as the police car. No, the ball must decelerate completely before terminal velocity measurements can be taken. The study of wall effects on settling of spherical particles has also been an area of research over the past years 38-42. The card stock is then folded in half and released a second time. Have group member 2 hold coffee filter at dropping height.
