Notesheet: Two-Dimensionsal Motion and Trajectories
Objective:
Use your Review book, Reference Table & Notepacket to complete the
notesheet.
1. “The motion of an object traveling in a two-dimensional plane can be described
by separating its motion into the ______________ and _____________
components of its _____________, _____________, and _______________ .
A component parallel to the horizon is a _______________________ and
a component at right angles to the horizon is a ___________________________ .
If air resistance is neglected, an example of two-dimensional motion is the motion
of a cannonball projected (launched or fired) near the surface of the Earth at an
angle to the horizontal. If gravity is the only unbalanced force acting on the
cannonball, the _______________ of the ball’s motion is identical to that of a
______________________, and the ______________________ is
__________________________. Although the two motions occur simultaneously,
the two components of the motion are ________________. Thus, if the object’s
initial velocity is known, the motion of the object in Earth’s gravitational field
can be described by the ____________ of the two motions.
2. Vocabulary:
Projectile:_________________________________________________________
Range:____________________________________________________________
Muzzle velocity:____________________________________________________
Trajectory:________________________________________________________
Horizontal component:_______________________________________________
Vertical component:_________________________________________________
