Definition of Projectiles

Projectile refers to the motion of a body which travels freely in space but under the influence of gravity and air resistance. When a ball is kicked into the air, it will travel through space in a plane. The motion in a plane is a combination of upward and horizontal motion.

The path through which a projectile travels is called trajectory.

Examples of Projectiles

In sports;

  • Throwing of discus
  • Throwing of javelin

In warfare;

  • Firing of catapult
  • Shooting of arrows with bow
  • Launching of missiles

Miscellaneous;

  • Throwing of stones

 

Projectile of Bodies at Angle θ to the Horizontal

When a body is projected at an angle  to the horizontal, the trajectory is a parabola.
