Chapter 3 Projectile motion. Two. Kinematics in Dimensions. Projectile Motion. Projectile motion is motion in two directions Motion in the x-direction is independent of the y-direction Motion in the y-direction is independent of the x-direction. V y. V x. The Full Parabola.
Kinematics in Dimensions
VxThe Full Parabola
Horizontal velocity (vx) has no affect on flight time because it is not affected by gravity.
Jill drops the yellow ball and throws the red ball horizontally. Which ball will hit the ground first?
X & Y are Independent horizontally. Which ball will hit the ground first?
Not all object are launch horizontally
Objects can be launched at an angle
Solve each direction (x & y) separately
Symmetry can be used when the launching & landing places are the same height.
Find the maximum height
What is true about the vertical velocity at the maximum height?

Please Note: horizontal and vertical components are independent of one another. The only commonality is time.
