When an object (stone, spear, arrow or bullet) is thrown, hurled or shot in the air, the object is a PROJECTILE (“Projectile”). The study of projectile is important because it must be realized that they are very much part of man’s daily life then and now. Whether man likes it or not, he encounters and uses projectile in his everyday life. Our hunting ancestors threw stones and spears on animals to kill them for their food. In today’s sports, balls follow projectile motion such as when a basketball player shoots the ball into the hoop, a golfer or a baseball player hitting the ball, a tennis player lobbing the ball, a javelin thrower, a discus thrower or a shot putter trying to throw their objects as far as they can (Sears, Zemansky and Young 54). In warfare, catapults and arrows in medieval times were the deadly weapons while today, guns, mortars, rockets and missiles have replaced those ancient weapons of war (“Field Artillery and Mortars”, “Ballistics”). However, the way to effectively use these weapons has not changed. They are to be launched into projectile motion to hit the target. The path followed by a projectile is called its trajectory. Projectiles follow a curved trajectory or curved path that is a PARABOLA. (Sears, Zemansky and Young 54, Briggs 491). It is actually easy to observe projectile motion when we use a light material as the projectile. For example, crumple a sheet of bond paper into a small ball. On a standing position, throw the paper ball straight horizontally. Observe that as the ball moves, it curves downward. Even if you try to throw it harder, it will still follow a curved downward path but will land farther. So, the harder you throw the object straight horizontally, the farther it will land. The distance where the object lands measured horizontally from the point you threw it to the point where it landed is called the RANGE of the projectile. The range of the projectile can be increased by...

Trajectory of a Projectiles
PROBLEM STATEMENT:
A spherical ball was projected from a fixed point ,O, with a speed ,u, angels of elevation : 0, 10, 20, 30, 40, 50, 60, 70, 80, 90 to the horizontal ground surface. Find the value of maximum height travelled by the ball for which the horizontal range, R, greatest for the same value of u.
AIM:
To investigate:
1)Range of projected ball.
2)Time of flight for corresponding angel of projection...

...Investigating Projectiles
Background:
A projectile is an entity which only has the force of gravity acting upon it. A projectile can be cast, fired, flung, heaved, hurled, pitched, tossed and thrown. A projectile can be anything as long as it has initial horizontal velocity that is not equal to zero which has the acceleration due to gravity. Projectile motion happens when an object projected with a force stops putting...

DISCUSSION
Projectile motion is a form of motion in which an object or particle (called a projectile) is thrown obliquely near the earth's surface, and it moves along a curved path under the action of gravity only. The path followed by a projectile motion is called its trajectory. Projectile motion only occurs when there is one...

...focus was projectile motion. A projectile is an object flying through the air that is only under the force of gravity (neglecting air resistance). A projectilemoves both horizontally and vertically, which creates a parabolic flight path. In vertical projectile motion there is a constant velocity since there are no forces in the horizontal direction (neglecting drag due to air resistance). Consequently, there is no...

Experiment # 4
Introduction:
Projectile Motion exists commonly in our everyday lives and is particularly evident in the motion or flight of objects which are projected from a particular height. The key to working with projectile motion is recognizing that when an object with mass is flying through the air, its motion is a combination of vertical and horizontal movements. Although the horizontal velocity of the object remains...
