The two pictures below demonstrate the calculations from Trial 1 at 0° and Trial 1 at 45°. In this experiment we did five separate shots from the cannon at 0°, and 3 separate shots at 45°. We determined the average distance of the shots from each angle by using a meter stick. We were then able to calculate the velocity of the shots by dividing the time from distance. After getting the results, the distance from the shots fired at 45° had a greater distance from the shots fired at 0° horizontally. This is because as the ball which is fired increases, the height increases. As the height increases, the time it takes for the ball to hit the ground increases and the range (distance) is greater.

Conclusion:
One source of error comes from when we shot the cannon from the ground at a

This experiment was to use kinetics of projectile motion and free falling bodies to determine the distance a ball will travel after it hits a bounce plate. To determine this we had to use the equations x=(1/2)at2 and v=v0+at and derive an equation that will determine the distance the ball will travel based on the height of the bounce plate and the height of where the ball will be dropped above the bounce plate. The equation made was g*(sqrt(2)/sqrt(g))*(sqrt(H)*sqrt(h)). From here we can make an estimate of how far the ball will travel after it hits the bounce plate.…

This investigation aims to explore the different paths of shots used in Beer Pong which is a drinking game that involves a ping pong ball and usually 20 cups. This topic is of significance to many teenagers and early adults as it addresses the techniques used in a game played at almost every party. I am very interested in projectile motion as it is part of the topics we cover in HL physics and this also links to a very fun game. It is also one of the topics included in engineering courses which is what I plan to study at university level therefore this gave me the opportunity to improve my knowledge in a future area topic. In HL…

To graphically analyze motion, two graphs are commonly used: Displacement vs. Time and Velocity vs. Time. These two graphs provide significant information about motion including distance/displacement, speed/velocity, and acceleration. The displacement and acceleration of a moving body can be obtained from its Velocity vs. Time graph by respectively finding the area and the slope of the graph.…

You have learned that the motion of any object moving through the air affected only by gravity is an example of projectile motion. Examples of projectile motion include a basketball thrown toward a hoop, a car driven off a cliff by a stunt person, and a marble launched from the CPO marble launcher. Toss a ball some distance and you can imagine in your mind the arc it follows, first rising then falling to the ground. Projectile motion is also called two-dimensional motion because it depends on two components: vertical and horizontal. The range is the horizontal distance that the projectile travels between launch and landing. In this experiment, you will see how the range is related to the launch angle and initial velocity of launch.…

The purpose of this experiment was to find the effect of the distance ran before kicking a soccer ball on the distance the ball travels. The data collected shows that as the distance ran before kicking the ball increased, the distance the ball traveled increased. In other words, the farther back the person started running towards the ball, the farther they were able to kick it. When starting at 0 meters, the person had an awkward kick because they weren’t able to get a running start, making the ball not go very far. However, as soon as they were able to start further away from the ball, at 1 meter, the ball went a lot farther because they had more momentum going into the ball. The hypothesis was if the distance before kicking a ball is increased,…
