17 November 2013 AP physics laboratory 1. Title
The investigation on the range, time, initial height, initial velocity, angle of throw, horizontal velocity and vertical velocity of projectile motion 2. Abstract In this laboratory, we measure the range, time, initial height, and initial velocity, angle of throw, horizontal velocity and vertical velocity firstly. After analyzing the measurements and calculations, we find out the conclusions about the relationships between these variables. 3. Interaction Our target is to find out and summarize the relationships between the variables in the projectile motion include range, time, initial height, initial velocity ,angle of throw, horizontal velocity and vertical velocity with the formulas that we have learned from the class. 4. The experiment
Procedure
Prepare a new tennis ball. Then add some detergent powder to the tennis ball. Thus when the ball falls and hits the floor, it will leave a point that has white mark on the ground. 2. Throw the tennis upward and begin to time. 3. As soon as we hear the voice of the strike, which implies that the tennis falls to ground, stop timing and record the lasting time in the rough data sheet. 4. Use a soft meter ruler to measure the distance between my partner standing positions and where the balls fall into ground and left white mark. 5. Use the ruler to measure the height of my partner; record the value as the Initial Height in the rough data sheet.
6. Adjust our force to throw the tennis again in order to change the range and the lasting time.
7. Repeat procession 1 to 6 until we get enough data.
8. Collect the data and finish the analysis of the data. 5. Experiment conclusion and discussions
Formula used in calculations
Horizontal Velocity: r／t Vertical Velocity: Angle of the Throw: Initial Velocity: Expression of Range Range: R=（2V0²／g) sinθ cosθ R= (V0²／g) sin2θ R=v * t * cosθ Either or can be used since Horizontal Velocity does not change at all. 6. Addendum
The angle that produce greatest range (ignore air resistance) If we combine the function Range= R=v * t * cosθwith t=(2V0／g)sinθ together, we can get R= (V0²／g) sin2θ. Because V is fixed, the value of sin2θ is critical. With a graphing calculator, get the maximum value of,sin2θ,1, with θ equals to 45. Then we can prove that the angle that produces greatest range is 45.
Maximum range achieved in the angle that produce greatest range and the reason why the experimental result does not match it ( according to the first conclusion in the addendum )
If we use the function R= (V0²／g)sin2θ, and sin2θ=1. We suppose that the Velocity is 5m/s, the Range will be s²／9.81, which equals to 2.548m.

7. Data Table
Tools:
Initial Height: Soft meter ruler
Range: Soft meter ruler
Time: IPhone
Methods of measurement:
Initial Height-the height of my partner
Range: the distance from the white mark of the impact point to my partner
Time: the whole time interval that the tennis keeps the projectile motion
Methods of calculations: we use EXL to calculate the data automatically)

Personal Narrative: AP Physics

Every time I walked into AP Physics, I distinctly remember my hand shaking. My jaw tensing. My brow furrowing. The scent of sweat permeated the air and a thick, dark, cloud of confusion reigned over me. It wasn’t as if I didn’t enjoy the subject; the sciences have always nestled themselves deep into my heart. But not AP Physics. No. In a time of what should have housed my academic highlight reel, I was floundering; lost in a sea of equations, forces, and xₒ. I’m not going to bore you with all of…

Personal Narrative: Physics

courses stood out in a particularly dull fashion. To this day my most beloved class is Physics. In fact after taking my first AP Physics course during my junior year, I further indulged myself with Physics during my senior year in AP Physics C. Physics has transcended me to take a more observant approach to a multitude of circumstances. The analytical tools that I have been fortunate enough to receive from my brief Physics career- seeking out facts and deciphering what they conclude- have allowed me to…

I am not equal to a boy who has the same grades. I am not equal to a boy who is in the same class, reading the same exact textbook as I am. I am not equal to a boy who is struggling in the same subject. I am not equal to a boy because nobody expects me to achieve as much as a boy can without working harder. I am not equal to a boy because there is still sexism in the classroom. Boys make up 86% of engineering jobs on the globe, because boys do not grow up in a world that discourages focus on harder…
