physics. said:Well I know the displacement north is 30m, because i was given an acceleration and a time. From that I found the final velocity of 50m/s from the triangle these two velocities created. Using the motion formula V22 = V12 + 2ad , i found the displacement to be 90, not 260... And I have no idea how to use vectors in this case to find a direction
1D motion refers to motion that only occurs along a straight line, while 2D motion involves movement in two perpendicular directions, typically represented by the x and y axes.
In 1D motion, displacement is simply the difference between the final and initial position of the object. In 2D motion, displacement can be calculated using the Pythagorean theorem, where the displacement is the square root of the sum of the squares of the x and y displacements.
In 1D motion, average velocity is calculated by dividing the total displacement by the total time. In 2D motion, average velocity is calculated by dividing the total displacement in the x and y directions by the total time.
In 1D motion, acceleration can change the speed or direction of an object's motion. In 2D motion, acceleration can change the speed or direction of an object's motion in both the x and y directions.
1D motion can occur when a car travels along a straight road or when a pendulum swings back and forth. 2D motion can be seen when a ball is thrown in the air, when a plane flies in the sky, or when a person walks in a zigzag pattern.
