2-Dimensional Motion

Motion that occurs only in a straight line

Motion that requires both horizontal and vertical components

Motion that is only affected by friction

Motion that occurs only in a circular path

-g

The maximum height is reached when the vertical velocity is zero.

The horizontal acceleration is zero.

The vertical acceleration is equal to -g.

The horizontal velocity increases during flight.

v_iy = 25sin(35°), v_ix = 25cos(35°)

v_iy = 25cos(35°), v_ix = 25sin(35°)

v_iy = 25tan(35°), v_ix = 25cot(35°)

v_iy = 25, v_ix = 35
