Trajectory of a projectile

Trajectory classification serves as the basis for abnormal activity detection. By analyzing the position, speed and appearance of the tracked object’s trajectory and then comparing those trajectories to the “normal” standard used to train the system, ABORAT is “able to detect normal/abnormal activities” (Appiah & Hunter, 2009, p. 6). These activities are then used to determine if abnormal behavior is present (i.e. behavior detection) and, if required, issues one of three alerts, “object type, zone and tripwire violations and the behavioral alert” (Appiah & Hunter, 2009, p. 7). In short, “The system is fully autonomous…capable of using the trajectory of moving object[s] to classify the behavior” (Appiah & Hunter, 2009, p. 8) and alerts monitors to the presence of abnormal behavior. Initial tests yielded promising results with a 4.4% error rate for data collected on a normal day and 14.5% error rate for data collected on a rainy day (Appiah & Hunter, 2009, p.…

is metric!) projectiles at their enemies. “Trebuchet” is derived from the Middle French verb trebuch, meaning “to tumble or fall over,” in reference to the throwing arm of the trebuchet. Though the first instance of tension or torsion-based artillery is thought to have originated in China as early as the fourth century, the trebuchet was the first war machine to use gravitational and leverage principles to launch a projectile. A catapult uses the elasticity of different materials to provide the…

Introduction When playing sports, it is very important to know what can help you improve. The next thing is to find out what that is. Golfers have certain golf clubs that have different angles for different types of ranges. Drivers are used for the greatest distance needed, such as the first hit. There are a few things that have an important job in this experiment. Projectile Motion plays a big role in many things such as sports. Projectile motion is an object or body moving through air…

It will explain how the projectiles and the parabolic actually work. Using an incline plane Galileo experimented acceleration motion and he will use the same projectile motion to study. He placed a inclined plane on a table with a curved piece at the bottom which deflected a bronze ball into a horizontal direction. The ball results accelerated rolled over the table top with a uniform motion then rolled of the edge of the table on to the floor where it left mark. The mark could be measured…

given set of velocity and height from the ball. The height of the ball when it leaves the horizontal projectile is at 93.5cm or .935m. The velocity of the ball was .0674 seconds in the range of .1 meter. Creating a total velocity of 1.484m/s. To calculate the hang-time the formula: y= -4.9t^2 was used. The hang time is used to figure out how long the ball will be in the air for. After you find the answer, the time is then multiplied by the velocity to get the range. The horizontal…

What are the x and y components of acceleration when the projectile is in motion? Call y positive upwards. The x component of acceleration is zero because projectiles have a constant velocity, resulting in no horizontal acceleration. The y component of acceleration is a constant -9.8 m/s2 in relation to the gravitational force acting on the projectile. Why does the x component of velocity remain constant? The x component of velocity remains constant because since the horizontal acceleration is…

with a photo of the crew (our heroes) astronauts and a specific logo for each mission. This space mission and every other mission are primarily based on the principles of projectile motion for launching. When the space shuttle is launched in to space, it takes a curved path called the trajectory to finally land in to an orbit. This trajectory is necessary for any launch as it will determine the time of launch, and the angle of inclination. Several calculations will have to be carried out to…

So the Physics of a palm ball are similar to a normal pitch. An object that is launched( by being thrown, kicked ,or otherwise) through the air is called a projectile. A projectile has an initial velocity (its speed and direction of motion). When a projectile is moving through the air, however, depending on the force of gravity, which causes it to move down toward Earth. It is also depending on the force of air resistance, which slows the projectile down. When air resistance is low, a projectile…

WAR MATHS- PROJECTILE MOTION Sun Tzu, the man whose name is famed by the phrase, the art of war, once said “Victorious warriors win first and then go to war, while defeated warriors go to war first and seek to win. ” which means victors were the ones who calculated and analyzed their opposition and factors that would ensure their victory. Cannons and catapults in my view, were the earliest form of artillery used for fighting wars with great separation distances between the parties at war. Bows…

accelerate the object and (Pearson science ,2012). The motion of the projectile launched is parabolic and is influenced by factors such as the mass of the counter weight, the length of the pivot arm…
