Projectile & Projectile Motion
It is a common experience that children love to throw stones at birds on trees or throw sticks at mango trees in order to make mango fruits fall from their branches. The stone which is thrown into the air, or a stick into the tree is regarded as a projectile.
Any object thrown into the air and allowed to fall freely under the influence of gravity is called a projectile.
The trajectory, or curved motion, or the path taken or described by a projectile while in the air is a trajectory.
A projectile motion is a curved motion described by a falling object in the air.
Examples of bodies exhibiting projectile motion are:
- A thrown javelin.
- A thrown discus.
- A thrown shotput.
- A bouncing table tennis ball from the wall.
- A fired missile.
- A thrown bomb.
- A thrown spear.
- A fired bullet from a gun.
- A shot stone from a catapult.
Applications of Projectile:
- It is used in warfare to hit an enemy target.
- It is used in sports by throwing a javelin, discus, etc. at 45° to obtain maximum range.
