It is derived using the kinematics equations: a x = 0 v x = v 0x x = v 0xt a y = g v y = v 0y gt y = v 0yt 1 2 gt2 where v 0x = v 0 cos v 0y = v 0 sin Suppose a projectile is thrown from the ground level, then the range is the distance between the launch point and the landing point, where the projectile hits the ground.

Web16. Projectile motion is the motion of an object thrown (projected) into the air. After the initial force that launches the object, it only experiences the force of gravity. The object is called a projectile, and its path is called its trajectory. As an object travels through the air, it encounters a frictional force that slows its motion called air resistance . WebAug 2, 2024 · The horizontal motion of the projectile is the result of the tendency of any object in motion to remain in motion at constant velocity.
