![]() Three-dimensional motion would be a case where the path is more complex and is not confined to a single plane. Examples are projectile motion where the path is a parabola, or planetary motion where it is an ellipse. In two-dimensional motion, the path the object follows lies in a plane. How can you identify a two or three dimensional motion? ![]() Projectile motion is a form of motion where an object moves in a bilaterally symmetrical, parabolic path. The trajectory of a projectile is a parabola. What do you call the trajectory of projectile? For 1D measurements data are only collected beneath a single point at the surface, for 2D a profile is measured and, for 3D, data from across a volume of ground is collected. The difference between 1D, 2D and 3D geophysical measurements is related to how you measure and process the data you collect. Projectile motion is a two dimensional motion with constant acceleration. The horizontal motion of a projectile is always constant, if we neglect air resistance. The 2-D motion of a projectile can be separated into two 1-D motions: horizontal and vertical. The horizontal and vertical motions of a projectile are independent, meaning they do not affect each other. Is projectile motion horizontal or vertical? Motion in two dimensions involves vector quantities: displacement (x, y) velocity (vx, vy) acceleration (ax, ay) Under ordinary circumstances, we can separate the components of a 2-D problem, creating two independent 1-D problems. An example of linear movement would be a car moving along a straight road or a ball thrown straight up from the ground. The simplest motion would be an object moving linearly in one dimension. Two-dimensional (2D) motion means motion that takes place in two different directions (or coordinates) at the same time. While throwing a basketball into the basket, the player shoots the ball in such a way that the flight taken by the ball is in the form of a parabola. Playing basketball, football is examples of projectile motion in real life. In real life, the projectile motion finds applications in sports. How is the concept of projectile motion used in real life cite at least two examples?
