Final Velocity Lab

Once in the gym, Rachel set up the popper with the small wooden ball, Jonah again holding the meter stick nearby. I again recorded a video of the ball’s flight but from a greater distance. The group then watched the video in slow-motion and determined the peak of the ball. The height was determined by setting up a proportion; for example, if the meter stick was about .005m tall on the video, and the ball flew to a height of about 0.02m on the video, then the ball flew to a height of 4.00m. This method removed much of the precision of the measurements: the group could not see the ball well from the distance at which the videos were taken and the measurements of the meter stick and height on the videos were estimated rather than truly measured. Despite lack of control over the values, here are the values we recorded for each ball, adjusted to 3 sig

The balls velocity and speed is increased significantly in a very brief period, right before the full extension of the elbow.

Some of these factors are gravity, the air resistance, the speed of release, the angle of release, and the height of release. The most basic and principal factor acting on a projectile is gravity. Gravity affects every object. It decreases the height that a projectile can attain. Air resistance is also a key factor working on an object. The larger the surface area, the more air resistance will affect a projectile. Air resistance will also affect an object more if it has a smaller mass. Also, the faster the speed of the projectile, the greater the air resistance. The speed of release refers to how fast an object is released and is directly related to the distance of the flight. The greater the speed of release and object has, the greater the distance the object will have. The initial vertical velocity increases the height of trajectories, creating a longer flight path. Similarly, as the initial horizontal velocity increase, the longer the length of flight and distance. The angle of release is the angle that an object is thrown or hit into the air. It changes the relationship

9. The total energy is constant for most of the time until the ball is released and caught up and down in free fall, because extra force of the person actions changes the energy. The energy should remain constant because the kinetic and potential ratio energy

Objective: Using a marble launcher, launch marbles from different angles with different forces to find the maximum height and the velocity as it leaves the launcher. Using different variables and results to determine how the different angles and amounts of force effect the variables. With this data show the effect the forces cause in 1-D and 2-D motion, as well as in the X and Y directions. This is done through kinematic equations and calculations.

In the equation (½)(M+m)v2, we are able to observe that kinetic energy of the air track increases

Describe in your graph of position vs. time when this would occur. (Hint: Is the slope of the tangent line to the curve positive or negative?)

An experiment was set up with the goal to prove a hypothesis created, which stated that the mass of a marble would not have any effect in the acceleration of that specific marble as it moves down a ramp. During the testing of the hypothesis, the data collected demonstrated that the acceleration of three different marbles with different masses were nearly identical, which reinforced and proved the hypothesis. Acceleration is the rate at which the velocity of an object changes, and velocity is the speed of an object in a specific direction. To test the hypothesis, a marble had to be released right behind a photogate on a ramp, which was placed on the tenth hold. As a consequence, it was impossible for the marble’s time to be recorded with an

Lastly, the launch angle also has a great effect on the distance traveled. If projected at 90° the ball would only be thrown vertically upwards and back down to the person. There would be no horizontal change in position but a great maximum height. The greatest horizontal distance is reached between 40° and 50°. For this reason the launch angle affects the

1. The Part 1 set up was prepared on the table, with the tennis traveling along the two rulers. The distance between the two rulers did not change throughout the experiment. Pens were placed at the 20, 40, 60, 80 and 100cm mark on the ruler to establish the 20cm increments. 2.

The velocity of the ball increases in the opposite direction as it has started to rebound from the ground with acceleration still pointing up (see Figure 5). This also means that the elastic potential energy is transferring into kinetic energy, although the kinetic energy will be less than previous because some of the energy has been lost to generate heat and sound when the ball lands and deforms. Due to the loss in energy, the ball will not return to its original drop height and creates a bounce height.

The goal behind this experiment was to estimate the distance a ball would travel after it falls a certain distance and bounces off a metal plate which has an angle of 45 degrees. To find this we had to take the basic equations for kinematics which are (1/2)at2=x and v=v0+at and combine them to make an equation that will help us solve for the distance the ball will travel after hitting the bounce plate. The equation came out to be R=g*(sqrt(2)/sqrt(g))*(sqrt(H)*sqrt(h)), as that g is acceleration of gravity, h is the height of bounce plate, and H is the height of where the ball will be dropped. After completing this experiment the result was that the standard deviation was +/- 2.3 cmfrom the

We have this problem with the ball “dropping” at an apparent average of 1.2 feet per second, according to the article. That’s hardly a drop in anyone’s book. Since any object in freefall accelerates at an average of 32

This can be done by using differential calculus to the find the function of the velocity of the ball after t seconds, the vertical velocity at a known time during the ball’s motion, and to calculate the maximum height of the ball. This lab also taught us how to apply differential calculus to find the position, time, velocity, and acceleration of an object when given the object’s position versus time

Following the first two deployments of Umoja, the Umoja Post Implementation Review Task Force – UPIRTF was created to identify issues surrounding the implementation of Umoja in field missions (PK and SPMs) and recommend corrective actions to adjust organizational aspects, policies, procedures and control mechanisms to effectively complement the operation under the Umoja model.
