projectile motion :: an object launched into space without motive power of its own is called a projectile

If we neglect air resistance, the only force acting on a projectile is its weight, which causes its path to deviate from a straight line. The projectile has a constant horizontal velocity and a vertical velocity that changes uniformly under the influence of gravity.

Horizontal and vertical motion of projectiles are independent, meaning horizontal motion does not influence vertical motion. The link between the two is time only.

Oblique Projectile Motion

Oblique projectile motion is when an object is launched at an angle.
