Physics Projectile Motion

____________ is a combination of vertical and horizontal motions that are completely independent of each other.

The ______________ can also be denoted as the point of origin of the motion of any moving body or object. It can also be pointed in the coordinate system that refers to starting positions of a particle in motion.

What is the definition of 'trajectory'?

• The path followed by a projectile flying or an object moving under the action of given forces.

• A type of geometric shape with four sides.

• A method of calculating the area of a circle.

• A process of photosynthesis in plants.
