Abstract

Velocity, Angle, and Gravity vs. Projectile Motion.

The purpose of my project is to answer the question “Does Angle, Velocity, And Gravity affect were a ball will land?”  I predict that Angle, Velocity, and Gravity will affect were a ball will land.  I also predict that the more Velocity you have the farter it will go. Also the less gravity you have, the higher the ball will go.  In my project I tested all three and my hypothesis was correct.  My results show that the more velocity I had the farther the ball went.  The less gravity the higher the ball went. Angle, Velocity, and Gravity does affect were a ball will land.  My conclusion is that I have correctly predicted that Angle, Velocity, and gravity will affect were a ball will land.
 

Experimental Design

Problem – Does Angle, velocity, and gravity affect were a ball will land.

Purpose – The purpose of my project is to answer the question “Does Angle, Velocity, and Gravity affect were a ball will land.

Hypothesis – I predict that all three (Angle, Velocity, and gravity) will affect were a ball will land.  I also predict that the more Velocity you have, will make the ball go farther.  Also the less gravity you have , the higher the ball will go.

Variable – When testing the Angle, the variable was Gravity and Velocity.  For testing Velocity, the variable was Angle and Gravity.  For testing Gravity, the varible was Velocity and Angle.

Measured Data – The data that was measured was how far the ball went when the Different settigns were set.

Control – No Control

Materials – Computer, Projectile Motion website simulater, and printer

Controlled Conditions – Some times I keep the velocity and Angle the same.  Other times I I keep gravity and Angle the same.  And finally I keep Velocity and Gravity the same.

Experimental Procedure

Step 3 – Change the numbers on one of the parts.

Step 4 –keep changing the numbers until I get 5 results.

Step 5 – Print out the resolts

Step 6 – Repeat step 3 , 4 , and 5 but change a different part.

Step 7- Repeat step 6

Experimental Data Collected

Experimental Data Analysis: Graph of Data

Experimental Write Up

Results - The results were that the more velocity the ball had, the farther the ball went.  Also the less gravity that the ball was in, the higher it would go.  The graph shows how the average amount of gravity showed that it landed pretty far from the cannon.  The average amount of velocity shows that it didn’t land that far from the cannon.  Finally the average amount of the Angle shows that it landed the farthest from the cannon.

Conclusion – My hypothesis was correct.  My prediction that the more Velocity a ball had, the farther it went.  Also my prediction that the less gravity the ball was in the higher it would go.  Finally my prediction that Angle, Velocity, and gravity will affect were a ball will land is also true.

Application – People who would like to shot or throw a ball should have lots of velocity and a good Angle rate.

Recommendations –

            Reliable – Instead of only going to a certain amount of numbers for Velocity, gravity, And Angle, try to do more numbers.

            Accurate-I would measure by ones not by tens.

            Through – I would maybe test if wind affects were a ball will land.

Summary-I wanted to determine if Velocity, Angle, and gravity affect were ball lands.  I found that all three do affect were a ball will land
