One application of projections of vector arises in the definition of the work done by a force on a moving body. Find another application.

Answer 1

Another application of projections of vectors arises in the calculation of projectile motion. When an object is launched into the air at an angle, its motion can be broken down into two separate components: the horizontal motion and the vertical motion. The horizontal component of motion is unaffected by gravity and remains constant, while the vertical component is influenced by gravity and follows a parabolic trajectory. By using the projections of vectors, we can analyze and calculate the range, maximum height, and time of flight of the projectile.
