4 –H Shooting Sports - Trajectory

What Is Trajectory?

In physics trajectory is the path a moving object follows through space as a function Trajectory of time. The object might be a projectile or a satellite, for example. It thus includes the Time / meaning of orbit—the path of a planet, an Distance asteroid or a comet as it travels around a central mass. A trajectory can be described mathematically either by the geometry of the path, or as the position of the object over time. 1

http://en.wikipedia.org/wiki/Trajectory

What Do We Use Trajectory For?

Trajectory Scientists use trajectory everyday to calculate or predict with mathematical accuracy where an object will hit and/or land. For Time example, before astronauts landed on the moon in 1969 they had to calculate the trajectory they would use to land safely; their calculations took years of work and simu- lated practice. You also use trajectory when playing basketball. In order to shoot the ball and make a basket you must choose your trajectory and use repetition of that same Trajectory Time path to keep making shots. If you stray from your successful trajectory you will miss your next shot.

What is Velocity? How do you measure Velocity?

In physics, velocity is the measurement of the rate and direction of change in position of an object; both magni- tude (speed) and direction (time) are required to define it. Muzzle velocity is the speed at which a projectile leaves V = _∆D the muzzle of the gun. Muzzle velocities range from ap- proximately 800 ft/s (240 m/s) for some pistols and older ∆T cartridges to more than 4,000 ft/s (1,200 m/s) in modern rifles with high-performance cartridges to 5,900 ft/s (1,800 m/s) for tank guns. The velocity of a projectile is highest at the muzzle and drops off steadily because of air V= Average Velocity D= Distance resistance. http://en.wikipedia.org/wiki/Velocity T= Time

Chad is a member of the Green Mountain 4-H Shooting Sports club and loves to shoot rifles. He got to shoot his rifle three times. The first time he shot his rifle it took 1.3 seconds for the bullet to hit the target. The second time it took 1.9 seconds. And on the third try it took 0.6 seconds. Chad was standing 500 feet from his target, what was the Veloc- ity of the bullets Chad shot?

She got to shoot three times. The first time she shot her bow & arrow it took 3.1 seconds for the arrow to hit the target. The second time it took 2.7 seconds. And on the third try it took 3.4 seconds. Kelly was standing 100 feet from her target, what was the Velocity of the arrows Kelly shot?
