PROJECTILE MOTION Flashcards
When an object maintains a
CONSTANT CHANGE in velocity in a given
time interval
Uniform acceleration
describes the motion of points,
bodies (objects), and systems of
bodies (groups of objects) using
equations.
KINEMATICS
a form of motion where an object,
given an initial velocity is thrown or
projected and is allowed to be acted
on by gravity in a curved-like path.
HORIZONTALLY LAUNCHED PROJECTILES
launched at an
angle with respect
to the horizontal
and rises to a peak
while moving
horizontally.
ANGLE-LAUNCHED PROJECTILES
The CURVED
path results from
the combination
of Horizontal and
vertical motion
of a projectile.
TRAJECTORY
Initial Horizontal
Velocity = Final
Horizontal Velocity or ? = ?
Vix = Vfx
Formula for Vix:
Vix = dx/t
Initial Vertical
velocity (Viy) is ?
zero
formula for final velocity
Vf = √Vx sqrd + Vy sqrd
IN ANGLE LAUNCHED PROJECTILES, Horizontal velocity
is ?
constant.
IN ANGLE LAUNCHED PROJECTILES, Vertical velocity:
? as the
projectile goes upward
decreases
IN ANGLE LAUNCHED PROJECTILES, Vertical velocity:
becomes ? when it
reached the max. height
0
IN ANGLE LAUNCHED PROJECTILES, Vertical velocity:
? as the projectile
move downwards
increases
IN ANGLE LAUNCHED PROJECTILES:
formula for Viy
Viy = Vysintheta
IN ANGLE LAUNCHED PROJECTILES:
formula for Vix
Vix = Vx =Vixcostheta
