a projectile is the answer
Projectile. You have spelled it correctly.
To propel a projectile.
They were shooting projectile out of their guns.
A projectile need not revolve at all in order to be a projectile.
An example of a projectile is a missile or a bullet.
In a perfect system, with no air resistance, the arc that a projectile moves through is a parabola. The shape of the parabola is dependent of various parameters including the initial velocity (speed and angle of launch) as well as the prevailing gravity. It could also describe a circle if the launch criteria are just right for the gravity, such as a satellite orbiting the Earth.
An object that is projectile is an object that is moving through the air. When you throw an object it is projectile.
