Introduction Projectile motion is key component in everyday life. Whether it’s a football player kicking the ball to score a winning field goal or a frustrated student crumpling up a piece of paper and tossing it into the trash can, projectile motion is all arounds us. The idea of projectile motion was taught to us by varying physicists like Aristotle and Galileo. Using Aristotle's original notion that shot objects stay along a straight path until its impetus is lost, the famous physicist Galileo discovered that projectiles instead follow a curved path. Galileo also found that projectile motion is understood by thinking of the horizontal axis and vertical axis separately.(1) Galileo and Aristotle’s ideas of projectile motion could be represented*…show more content…*

Using the equations from figure 3, and knowing the horizontal velocity is constant, we were able to find the total time for the motion. Using the equation 훥t=ΔdVav it was discovered that the total time elapsed during the projectile's flight was 1.56 seconds. The components of the motion can be separated into two components, vertical and horizontal (refer to Figure 1).To test the accuracy of this measurement, an equation can be used. The equation focuses only on horizontal components (Figure 1). To find the horizontal range, the equation 횫dx=Vav횫t +12a횫t2. Using the idea that a= 0m/s2,meaning that there is no horizontal velocity, we determined that the actual range of the object would be 19.59m. In conclusion, we found that the muzzle speed was 17.66m/s and the range was*…show more content…*

The theory is that when an object is shot at a 45° angle, it will have its maximum possible range. After shooting it with no angle upwards, and then with it’s 45° angle, it is quite clear that the theory is true. Shooting it horizontally with no angle provides us with proof, because it only shot a short distance before hitting the ground. The experiment differed from what was expected because it seems accurate that with a smaller gun, a smaller range would be fitting. This however, was not the case. Based on Aristotle’s theory that shot objects stay along a straight path until its impetus is lost, our experiment seemed to arch upwards and not follow any straight line (Figure. 2). Science is about testing the theories, and finding conclusions. Shooting a projectile out of a nerf gun tested Galileo's theory, and proved that he is indeed correct by assigning vertical and horizontal motion to a projectile motion. The data found proves how codependent the different aspects of the data are. For example, if the time was different by even 0.1 second, the projectile's range could be different by almost 2 metres. After the range was measured at 19.5m, it was decided that using equations would give a more accurate number.This was true as the actual range of the projectile was 19.59m. This provides our original measurement with a 45% measurement error. The experiment could be improved by

In the first Unit of class we talked about motion in one dimension, but in this unit we talked about motion two dimensional. One example of a two dimensional motion is projectile motion. Projectile motion is when an object has an initial force that is applied to it to begin its motion. After the object starts its motion there is no longer a force that is being applied. At this

Before this lab I could not tell how the angle and velocity would change the results. I needed to figure out what angle and what velocity made the object go farther or make it stay in the air longer. I also found mass will affect the height and distance. I used the site Galileo and

## Principles Of Trebuchet

Having the counterweight pivot around a much shorter distance than the projectile end gives an advantage to the projectile end of the beam to reach a much higher linear velocity than the counterweight end of the beam. This is the principle mechanical advantage that allows the projectile to have a high launch velocity. The main goal is to maximize the ratio of the length of

If the pendulums were set in motion on the red planet, how would that affect their periods? The periods would increase. Was it necessary to displace the pendulums by the same degrees? Why or why not? It was necessary to displace the pendulums by the same degrees because they had different measurements. In a lab, you may only have

## Mass And Weight Essay

1077 Words | 5 PagesTo distinguish between mass and weight, one must know the basic definition of the two terms. Mass is typically defined as a measurement of how much matter in in an object or amount of inertia it holds. While weight is a measurement of how hard gravity pulls on the object. The mass always contains the same amount of matter however, the amount an objects weighs may fluctuate due to the gravity. The weight of an object depends on where it is, whereas mass always remains the same; mass does not change
