Understanding Projectiles: Forces, Trajectories, and Real-World Examples
This article explores the concept of projectiles, defining what makes an object a projectile and how gravity influences its motion. By ignoring air resistance, we can understand the parabolic trajectory exhibited by various objects once they are propelled. Examples include a pitched baseball, a bullet, an uncompleted bridge incident, and various sports items like footballs and javelins. We also discuss the behavior of aircraft once engines are cut off. Discover the fundamental physics behind the motion of these projectiles and their real-world applications.

Projectiles 10 Projectiles By Ally Holland- Dor By: Ally Holland-Dor
A baseball that has been pitched, batted, or thrown The following is a projectile because the only force acting upon it if air resistance is ignored is gravity. Also the projectile has a parabolic trajectory.
A bullet the instant it exits the barrel of a gun or rifle The following is a projectile because the only force acting upon it if air resistance is ignored is gravity. Also the projectile has a parabolic trajectory.
A bus driven off an uncompleted bridge • The following is a projectile because the only force acting upon it if air resistance is ignored is gravity. Also the projectile has a parabolic trajectory.
A moving airplane in the air with its engines and wings disabled The following is a projectile because the only force acting upon it if air resistance is ignored is gravity. Also the projectile has a parabolic trajectory.
A runner in mid stride (since they momentarily lose contact with the ground) The following is a projectile because the only force acting upon it if air resistance is ignored is gravity. Also the projectile has a parabolic trajectory.
The space shuttle or any other spacecraft after main engine cut off (MECO)
A football kicked into the air The following is a projectile because the only force acting upon it if air resistance is ignored is gravity. Also the projectile has a parabolic trajectory.
An arrow flying toward a target The following is a projectile because the only force acting upon it if air resistance is ignored is gravity. Also the projectile has a parabolic trajectory.
A javelin flying through the air The following is a projectile because the only force acting upon it if air resistance is ignored is gravity. Also the projectile has a parabolic trajectory.
A tennis ball lobbed over the net. The following is a projectile because the only force acting upon it if air resistance is ignored is gravity. Also the projectile has a parabolic trajectory.
