Projectile motion is, by definition, an object moving through 3D space under the influence of forces not originated on the object itself. Thus, any ball, puck, javelin, or other object thrown, hit, kicked, or otherwise sent on its way by some burst of force and then left to move through 3D space under external forces, like gravity, drag friction, and elector-magnetic flux is a projectile in motion.

Note the following...

"pro·jec·tile (pr-jktl, -tl) KEY

NOUN:

A fired, thrown, or otherwise propelled object, such as a bullet, having no capacity for self-propulsion.

A self-propelled missile, such as a rocket." [See source.]

This is an unfortunate definition taken from an online dictionary. It is unfortunate because it is inconsistent. The first definition claims a projectile has "no capacity for sefl-propulsion." The second definition claims it is a "self-propelled missile."

As a rocket scientist with Lockheed Martin for six years, I never once considered the rockets I worked on to be projectiles. True projectiles are objects moving through 3D space without propulsion on board.

Projectile Motion In Sports

2016-11-04 08:39:07 · answer #2 · answered by konen 4 · 0 0

Golf. Think about it: you can try with a smooth ball or the dimpled ball for distance. Why does the dimpled ball go so much further than the smooth ball? Is there something more efficient in its flight path? Load A rig similar to your boot on a pole can be used to deliver straight shots, hooks and slices, so there's almost an endless variety of relatively simple measurements. And how a gofer can "curve" the flight path almost to right angles to where one would expect, Then there's the actual motion of the ball - it's NOT a simple ballistic projectile, but I'll leave you to figure that one out.

it is important to each and every one in our daily life,,,,The importance of projectile motion is different sports is that you ll excel in those sports.and If you are good with projectiles, you can determine the time, range, and many more. With that knowledge, you ll surely become an expert in no time!
,we also have different kinds of example inour daily lives ,like basketball,volleyball,and etc.

Good luck and God bless!

Football: Whenever the ball is kicked or thrown, it follows a ballistic trajectory.
Baseball: Whenever the ball is thrown or hit, it follows a ballistic trajectory.
Hockey: Whenever the puck is hit off the surface of the ice, it follows a ballistic trajectory.
Basketball: Whenever the ball is thrown, it follows a ballistic trajectory.

Starting to get the idea? Any time something travels through the air, it will follow a ballistic trajectory unless it has the ability to generate significant lift (such as a paper airplane does).

Foot ball, basket ball, volley ball, tennis, cricket, golf, hockey... all of them depend on the motion of a ball once thrown or hit.

Diving, ski board jumping etc. are examples where you are the projectile.
