Motion in two dimensions can be described in terms of the time t and the x and y components of four vectors: the displacement , the acceleration, the final velocity , and the initial velocity. The motion can be analyzed by treating the x and y components of the vectors separately and realizing that the time t is the same for each. The directions of these components are conveyed by assigning a plus ( + ) or minus ( - ) sign to each one. When the acceleration vector is constant, the x components of these vectors ( x, a x , v x , and v 0 x ) are related by the equations of kinematics, as are the

Unformatted text preview: y components ( y, a y , v y , and v y ). Table 3.1 summarizes the equations of kinematics for two-dimensional motion. Projectile motion is a kind of two-dimensional motion that occurs when the moving object (the projectile) experiences only the acceleration due to gravity, which acts in the vertical direction. The acceleration of the projectile has no horizontal component ( a x = 0), the effects of air resistance being negligible. The vertical component of the acceleration is a y , and it equals the acceleration due to gravity....
