PROJECTILE MOTION Projectile motion is the launching of

PROJECTILE MOTION Projectile motion is the launching of an object into the air. (shooting a gun, throwing a ball, …) When any object is launched into the air it changes its position along the ground (horizontally) and it position above the ground (vertically)

Motions of Projectiles The vertical (up/down) motion of a projectile is independent of the horizontal (side to side) motion. The horizontal motion is the same as a ball rolling on the ground. The vertical motion is the same as an object falling to the Earth because of gravity.

Forward Velocity of a Projectile Does how fast an object pushed horizontally affect how long it takes to hit the ground? Will a bullet fired from a gun hit the ground in the same amount of time as a bullet dropped from the same height? http: //www. youtube. com/watch? v=D 9 w. QVIEd. Kh 8

What if you launch a projectile at an angle? If a projectile is launched at an angle then it will change how far it will travel. The path that a projectile travels along is called a trajectory If you launch a projectile at an angle, any two angles that add up to 90˚ will travel the same horizontal distance

How fast will the projectile be going? At the top of its flight a projectile has no vertical speed. The vertical speed at the start of a projectile’s angled flight is the same as the projectile’s vertical speed at the start. -so if a projectile is launched at a speed of 50 m/s then it will land with a speed of 50 m/s

Calculating how far it flew R = v 2 sin 2θ/g R means range or how far the projectile traveled horizontally (in meters) v means the velocity that the projectile was originally shot at (in meters/second) Θ means the angle that the projectile was shot at g means the acceleration due to gravity (10 m/s 2)
