Jessica Yan Rick St. Denis, Tyler Wiseman 13 September 2012 Projectile Motion: Ball in the Bin Purpose: The purpose of the experiment is to determine the velocity of a ball launched from the Projectile Launcher device, and then to use that velocity to find where on the floor the ball will land given a specific angle. Theory: Two-dimensional motion is as it sounds, made of the two components of Vertical velocity and Horizontal Velocity. Horizontal Motion can be described as constant, neglecting air resistance, and Vertical Motion is characterized by the acceleration of gravity pulling at 9.8m/s². In this particular experiment, the total velocity will be split into the two components in order to find the time in the air, and horizontal distance from the launcher. The motion of these components can be described as d=vt for constant horizontal motion, and d=1/2at² + Vit.
Replace the ramp as in Figure 3.1. Figure 3.1: Equipment Setup Mark with pencil Photogate Use a plumb bob to determine the point directly below where the ball will leave the edge of the table after rolling down the ramp. Measure the distance from the floor to the top of the table at the point where the ball leaves the table and record this value as dy. Ramp Ramp To measure the position where the ball will strike the floor after rolling down the ramp, tape a piece of plain paper onto the floor with a piece of carbon paper on top. The impact ® LED comes ON LED goes OFF Figure 3.2: Measuring Dd 9 Photogate Timers 012-06379A of the ball will leave a clear mark for measuring
Next, using the equations the total distance the ball would travel was found. After that, the students called over Mr. Neenan so that he could observe the firing of the projectile launcher. The projectile launcher was at the end of the table and the calculated distance was marked off on the floor by a target. The projectile launcher was then set up perfectly horizontal and fired. Part Two: This part of the lab was to hit Mr. Bill with the projectile as he was sitting on the floor.
7. Drop the other ball, now called Ball B, from the top of the butcher paper. 8. Record the height of the bounce. 9.
19/04/12 Physics Lab Report : determination of Terminal Velocity Maksym Panas This lab investigates the velocity of a ball bearing falling through glycerin. A small metal ball bearing was released into tube,140 cm long, containing glycerin. When released , the bearing accelerated to terminal velocity and than maintained the speed until the bottom of the tube. I decided to find the clearings terminal velocity by comparing the distance taken for t to travel through the glycerin and the time taken to do so. Research Question : What is the terminal velocity of a ball bearing in glycerin?
Then I drew a semi-circle on the top of the intersection representing the flexi glass and placed the flexi glass over the semi-circle. 4. Plugged in the ray box to a power source and using the single slit barrier, I placed the light ray along the normal to ensure that the light is not bent at this point. 5. I then placed the ray box allowing the light ray travels along the 10° then marked the refracted light on the glass.
Lastly we will explore standing waves and how string oscillations become affected by the string mass density. Theory As stated in order above, our first experiment of simple harmonic motion using an oscillating spring setup. By using a mass hanger attached to a rotary motion sensor, we are able to produce graphs and data to attempt to show the proofs for the theories and equations listed in the theory and graph section of the lab. The experiment started with adding 200g and progressively moved up to 350g for five trials. We then collected the data and analyzed the sine graph and the different portions of it and what they meant including the parameters and taking proper data.
However, if an object were shot out of a gun for example , in a horizontal direction , then the force of gravity would directly act upon the object on its descent . When an object is projected at a specific angle, then your v is no longer v. In other words your final velocity is not equal to your initial velocity . The equation v=v cos is used. Experiment overview: In this lab , my partner and I performed multiple attempts to calculate the average distance a projectile would travel before hitting the ground when shot out of a gun in a horizontal direction . In the first trial , we shot the circular metal ball out of the gun at an angle parallel to the ground(0).The gun , itself , had three levels of compression .
Lab 8: Ballistic Pendulum Objective: In this lab we used three methods to measure the initial velocity of a projectile from a spring gun. In the first experiment we used kinematics alone to determine the mean initial velocity for the projectile. In the second experiment we added a simple ballistic pendulum to derive the velocity of the projectile using the principles of conservation of momentum and energy. In the third experiment we used a physical pendulum, the equations for conservation of angular momentum and energy, and the equation for the period to determine the initial velocity of the projectile. Description: In these series of experiments the apparatus we used was a spring gun that for the first experiment shot a steel ball freely which eventually struck the floor.
