The document discusses projectile motion, explaining it as the path an object follows when thrown under the influence of gravity. It outlines the independence of horizontal and vertical motions, detailing the characteristics of both types of projectile launches and their effects on velocity and acceleration. Additionally, it references curriculum guides and educational resources relevant to the topic.

2. Learning Targets
I can describe the horizontal and
vertical motions of a projectile.
I can investigate the relationship
between the angle of release and the
height and range of the projectile.

3. Studying projectile motion is like
looking at an optical illusion.

4. PROJECTILE
MOTION
A type of motion wherein an
object called a projectile is
thrown in the air and moves a
curved path under gravity alone

5. Types of Projectiles
Horizontally
launched Projectile
Nonhorizontally
launched Projectile
1 2

6.  No resistance in any form
 Constant horizontal velocity
 Zero horizontal acceleration
(ax = 0)
 Horizontal distance: Range
HORIZONTAL
MOTION
X-COMPONENT
VERTICAL MOTION
(FREE FALL)
Y-COMPONENT
COMPONENTS OF PROJECTILE MOTION
 Acted upon by gravity
 Accelerating vertical velocity
 Constant vertical acceleration
(g = ay = - 9.8 m/s2)
 Vertical distance: Maximum Height

7. y
HORIZONTAL
MOTION: Has an
initial horizontal
velocity that is
constant (neglecting
air resistance)
ax = 0
VERTICAL
MOTION:
accelerating
due to gravity
ay = -9.8 m/s2
PROJECTILE MOTION
- Has a curvilinear path
called trajectory
- Vertical & horizontal
components are
independent of each
other
Projectile Motion

8. INDEPENDENCE OF THE HORIZONTAL & VERTICAL
COMPONENTS OF PROJECTILE MOTION

9. PROJECTILE MOTION
o Neglecting Air Resistance
o Under the sole influence of gravity
 Horizontal velocity is
always constant
 Vertical velocity
decreases as the
projectile moves up
and increases while it
moves down along its
trajectory
Velocity
 Horizontal
acceleration is
always zero
 Vertical acceleration
is always equal to the
acceleration due to
gravity, -9.8 m/s2 (on
Earth)
Acceleration
 Horizontal distance –
range
 Vertical distance –
maximum height
Distance
